86039991 ÷ 848 
Our goal is to divide 86039991 by 848.

Going ahead to step 1:
If we divide 8 by 848, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 848

Going ahead to step 2:
86 divided by 848 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 848

Going ahead to step 3:
The number 848 fits into 860 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 848 from 860.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 848

Step 4:
848 can be fit into 123 0 times, resulting in a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 123 to get 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 848

Moving on to step 5:
848 can be fit into 1239 1 times, resulting in a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we subtract 848 from 1239, we get 391.
Bring next digit (9) of the dividend behind the 391 and repeat the process: 3919 / 848

Moving on to step 6:
The number 848 fits into 3919 4 times, leaving a remainder of 527.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
Subtract 3392 from 3919 to get 527.
Bring next digit (9) of the dividend behind the 527 and repeat the process: 5279 / 848

Advancing to step 7:
848 goes into 5279 6 times with a remainder of 191.
Write down 6 as next digit of the result. 
Result so far: 10146.0
The remainder is 191 after subtracting 5088 from 5279.
Fetch the next digit (1) from the dividend, attach it to 191 and continue: 1911 / 848

Advancing to step 8:
The number 848 fits into 1911 2 times, leaving a remainder of 215.
Write down 2 as next digit of the result. 
Result so far: 101462.0
If we subtract 1696 from 1911, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
2150 divided by 848 is 2 with a remainder of 454.
Use 2 as the next digit of our solution. 
Result so far: 101462.2
The remainder is 454 after subtracting 1696 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 10:
848 can be fit into 4540 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 101462.25
Subtracting 4240 from 4540 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
When dividing 3000 by 848, we get 3 with a remainder of 456.
The next digit of our result is 3. 
Result so far: 101462.253
The remainder is 456 after subtracting 2544 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 12:
The number 848 fits into 4560 5 times, leaving a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 101462.2535
Subtracting 4240 from 4560 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
848 goes into 3200 3 times with a remainder of 656.
Put 3 as the next digit of the answer. 
Result so far: 101462.25353
If we take 2544 away from 3200, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 14:
6560 divided by 848 is 7 with a remainder of 624.
Put 7 as the next digit of the answer. 
Result so far: 101462.253537
If we subtract 5936 from 6560, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 15:
848 goes into 6240 7 times with a remainder of 304.
Use 7 as the next digit of our solution. 
Result so far: 101462.2535377
The remainder is 304 after subtracting 5936 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 101462.2535377 with a remainder of 3.04e-06.
