\(\frac{423134.846267-423133}{846267.423133+423134}=\frac{\left(423134+1\right).846267-423133}{846267.423133+423134}\)
\(\frac{423133.846267+846267-423133}{846267.423133-423134}=\frac{423133.846267-423134}{864267.423133-423134}=1\)
\(\dfrac{423134.846267-423133}{846267.423133+423134}\)
\(=\dfrac{423134.846267-423133}{846267.\left(423134-1\right)+423134}\)
\(=\dfrac{423134.846267-423133}{846267.423134-846267+423134}\)
\(=\dfrac{423134.846267-423133}{846267.423134-423133}\)
\(=1\)
