We look at the division of 86680601 by 42 
Our goal is to divide 86680601 by 42.

Going ahead to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 42

Going ahead to step 2:
42 goes into 86 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 84 from 86 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 42

Advancing to step 3:
26 divided by 42 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 42

Let's proceed to step 4:
The number 42 fits into 268 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 206.0
The remainder is 16 after subtracting 252 from 268.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 42

Moving on to step 5:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 2063.0
Subtract 126 from 160 to get 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 42

Step 6:
42 goes into 346 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 20638.0
Deduct 336 from 346 and we're left with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 42

Advancing to step 7:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 206382.0
The remainder is 16 after subtracting 84 from 100.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 42

Going ahead to step 8:
When dividing 161 by 42, we get 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 2063823.0
Deduct 126 from 161 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
42 can be fit into 350 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 2063823.8
Deduct 336 from 350 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
If we divide 140 by 42, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 2063823.83
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
If we divide 140 by 42, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 2063823.833
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 2063823.833, with a leftover of 0.0014.
