83081377 ÷ 991 
Our goal is to divide 83081377 by 991.

Advancing to step 1:
If we divide 8 by 991, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 991

On to step 2:
If we divide 83 by 991, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 991

On to step 3:
The number 991 fits into 830 0 times, leaving a remainder of 830.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 830 leaves us with 830.
Grab the next digit (8) from the dividend, add it to 830, then carry on: 8308 / 991

Moving on to step 4:
The number 991 fits into 8308 8 times, leaving a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7928 from 8308 to get 380.
Fetch the next digit (1) from the dividend, attach it to 380 and continue: 3801 / 991

Moving on to step 5:
3801 divided by 991 is 3 with a remainder of 828.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2973 from 3801, we get 828.
Include the next digit (3) from the dividend after 828, then repeat: 8283 / 991

Moving on to step 6:
991 goes into 8283 8 times with a remainder of 355.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
The remainder is 355 after subtracting 7928 from 8283.
Fetch the next digit (7) from the dividend, attach it to 355 and continue: 3557 / 991

Moving on to step 7:
The number 991 fits into 3557 3 times, leaving a remainder of 584.
Use 3 as the next digit of our solution. 
Result so far: 8383.0
If we take 2973 away from 3557, we end up with 584.
Include the next digit (7) from the dividend after 584, then repeat: 5847 / 991

Advancing to step 8:
If we divide 5847 by 991, we get 5 and a remainder of 892.
Write down 5 as next digit of the result. 
Result so far: 83835.0
Deduct 4955 from 5847 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Going ahead to step 9:
8920 divided by 991 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 83835.9
The remainder is 1 after subtracting 8919 from 8920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
When dividing 10 by 991, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 83835.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
991 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 83835.9
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 83835.9 with a remaining 0.01.
