86934827 divided by 991 
Our goal is to divide 86934827 by 991.

On to step 1:
991 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 991

Moving on to step 2:
86 divided by 991 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 991

Let's proceed to step 3:
991 goes into 869 0 times with a remainder of 869.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 869 and we're left with 869.
Fetch the next digit (3) from the dividend, attach it to 869 and continue: 8693 / 991

Going ahead to step 4:
991 goes into 8693 8 times with a remainder of 765.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 7928 from 8693 and we're left with 765.
Fetch the next digit (4) from the dividend, attach it to 765 and continue: 7654 / 991

On to step 5:
991 goes into 7654 7 times with a remainder of 717.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 717 after subtracting 6937 from 7654.
Take the next digit (8) from the dividend and append it to 717, then repeat: 7178 / 991

Advancing to step 6:
991 goes into 7178 7 times with a remainder of 241.
Record the quotient 7 as the next digit in the result. 
Result so far: 877.0
Deduct 6937 from 7178 and we're left with 241.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 991

Advancing to step 7:
When dividing 2412 by 991, we get 2 with a remainder of 430.
Put 2 as the next digit of the answer. 
Result so far: 8772.0
If we subtract 1982 from 2412, we get 430.
Grab the next digit (7) from the dividend, add it to 430, then carry on: 4307 / 991

On to step 8:
991 goes into 4307 4 times with a remainder of 343.
Write down 4 as next digit of the result. 
Result so far: 87724.0
If we take 3964 away from 4307, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 9:
3430 divided by 991 is 3 with a remainder of 457.
Put 3 as the next digit of the answer. 
Result so far: 87724.3
If we take 2973 away from 3430, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Step 10:
991 can be fit into 4570 4 times, resulting in a remainder of 606.
Use 4 as the next digit of our solution. 
Result so far: 87724.34
Subtracting 3964 from 4570 leaves us with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 11:
The number 991 fits into 6060 6 times, leaving a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 87724.346
Subtracting 5946 from 6060 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 12:
991 can be fit into 1140 1 times, resulting in a remainder of 149.
The next digit of our result is 1. 
Result so far: 87724.3461
If we take 991 away from 1140, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 13:
1490 divided by 991 is 1 with a remainder of 499.
The number 1 becomes the next digit in our result. 
Result so far: 87724.34611
The remainder is 499 after subtracting 991 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

The quotient of the division is 87724.34611, and the remainder is 0.000499.
