80216176 divided by 991 
We want to divide 80216176 by 991.

Step 1:
The number 991 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 991

On to step 2:
991 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 991

Advancing to step 3:
802 divided by 991 is 0 with a remainder of 802.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 802, we end up with 802.
Fetch the next digit (1) from the dividend, attach it to 802 and continue: 8021 / 991

Advancing to step 4:
991 can be fit into 8021 8 times, resulting in a remainder of 93.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7928 away from 8021, we end up with 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 991

Let's proceed to step 5:
When dividing 936 by 991, we get 0 with a remainder of 936.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtract 0 from 936 to get 936.
Fetch the next digit (1) from the dividend, attach it to 936 and continue: 9361 / 991

Step 6:
991 goes into 9361 9 times with a remainder of 442.
Put 9 as the next digit of the answer. 
Result so far: 809.0
If we take 8919 away from 9361, we end up with 442.
Fetch the next digit (7) from the dividend, attach it to 442 and continue: 4427 / 991

Step 7:
If we divide 4427 by 991, we get 4 and a remainder of 463.
Put 4 as the next digit of the answer. 
Result so far: 8094.0
The remainder is 463 after subtracting 3964 from 4427.
Grab the next digit (6) from the dividend, add it to 463, then carry on: 4636 / 991

Moving on to step 8:
If we divide 4636 by 991, we get 4 and a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 80944.0
Deduct 3964 from 4636 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 9:
991 goes into 6720 6 times with a remainder of 774.
The next digit of our result is 6. 
Result so far: 80944.6
Deduct 5946 from 6720 and we're left with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Advancing to step 10:
If we divide 7740 by 991, we get 7 and a remainder of 803.
Put 7 as the next digit of the answer. 
Result so far: 80944.67
If we subtract 6937 from 7740, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Let's proceed to step 11:
991 can be fit into 8030 8 times, resulting in a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 80944.678
Subtracting 7928 from 8030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
When dividing 1020 by 991, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 80944.6781
The remainder is 29 after subtracting 991 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 991 is 0 with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 80944.6781
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
991 goes into 2900 2 times with a remainder of 918.
Record the quotient 2 as the next digit in the result. 
Result so far: 80944.678102
If we subtract 1982 from 2900, we get 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9180, and continue the process.

Moving on to step 15:
991 can be fit into 9180 9 times, resulting in a remainder of 261.
Write down 9 as next digit of the result. 
Result so far: 80944.6781029
If we take 8919 away from 9180, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 16:
The number 991 fits into 2610 2 times, leaving a remainder of 628.
Put 2 as the next digit of the answer. 
Result so far: 80944.67810292
Deduct 1982 from 2610 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

The quotient of the division is 80944.67810292, and the remainder is 6.28e-07.
