85372962 ÷ 861 
We want to divide 85372962 by 861.

Advancing to step 1:
861 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 861

Moving on to step 2:
The number 861 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 861

Going ahead to step 3:
When dividing 853 by 861, we get 0 with a remainder of 853.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 853 leaves us with 853.
Take the next digit (7) from the dividend and append it to 853, then repeat: 8537 / 861

Step 4:
861 can be fit into 8537 9 times, resulting in a remainder of 788.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7749 from 8537, we get 788.
Grab the next digit (2) from the dividend, add it to 788, then carry on: 7882 / 861

Going ahead to step 5:
861 goes into 7882 9 times with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 7749 from 7882, we get 133.
Take the next digit (9) from the dividend and append it to 133, then repeat: 1339 / 861

Moving on to step 6:
1339 divided by 861 is 1 with a remainder of 478.
The next digit of our result is 1. 
Result so far: 991.0
The remainder is 478 after subtracting 861 from 1339.
Fetch the next digit (6) from the dividend, attach it to 478 and continue: 4786 / 861

Step 7:
The number 861 fits into 4786 5 times, leaving a remainder of 481.
Record the quotient 5 as the next digit in the result. 
Result so far: 9915.0
Subtracting 4305 from 4786 leaves us with 481.
Bring next digit (2) of the dividend behind the 481 and repeat the process: 4812 / 861

Going ahead to step 8:
4812 divided by 861 is 5 with a remainder of 507.
Use 5 as the next digit of our solution. 
Result so far: 99155.0
Subtracting 4305 from 4812 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 9:
If we divide 5070 by 861, we get 5 and a remainder of 765.
Record the quotient 5 as the next digit in the result. 
Result so far: 99155.5
If we subtract 4305 from 5070, we get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 10:
When dividing 7650 by 861, we get 8 with a remainder of 762.
Use 8 as the next digit of our solution. 
Result so far: 99155.58
The remainder is 762 after subtracting 6888 from 7650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Let's proceed to step 11:
The number 861 fits into 7620 8 times, leaving a remainder of 732.
The next digit of our result is 8. 
Result so far: 99155.588
The remainder is 732 after subtracting 6888 from 7620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

The final outcome is 99155.588, with a leftover of 0.0732.
