82470655 ÷ 991 
Our goal is to divide 82470655 by 991.

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
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 991

Step 2:
991 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 991

Advancing to step 3:
824 divided by 991 is 0 with a remainder of 824.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 824, we end up with 824.
Bring next digit (7) of the dividend behind the 824 and repeat the process: 8247 / 991

Step 4:
8247 divided by 991 is 8 with a remainder of 319.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7928 from 8247 to get 319.
Take the next digit (0) from the dividend and append it to 319, then repeat: 3190 / 991

Step 5:
When dividing 3190 by 991, we get 3 with a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 83.0
The remainder is 217 after subtracting 2973 from 3190.
Grab the next digit (6) from the dividend, add it to 217, then carry on: 2176 / 991

Advancing to step 6:
991 goes into 2176 2 times with a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 832.0
Subtracting 1982 from 2176 leaves us with 194.
Take the next digit (5) from the dividend and append it to 194, then repeat: 1945 / 991

Advancing to step 7:
991 can be fit into 1945 1 times, resulting in a remainder of 954.
Write down 1 as next digit of the result. 
Result so far: 8321.0
Deduct 991 from 1945 and we're left with 954.
Grab the next digit (5) from the dividend, add it to 954, then carry on: 9545 / 991

Going ahead to step 8:
9545 divided by 991 is 9 with a remainder of 626.
The next digit of our result is 9. 
Result so far: 83219.0
If we take 8919 away from 9545, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 9:
6260 divided by 991 is 6 with a remainder of 314.
Write down 6 as next digit of the result. 
Result so far: 83219.6
Subtracting 5946 from 6260 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 10:
3140 divided by 991 is 3 with a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 83219.63
Subtracting 2973 from 3140 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 11:
991 goes into 1670 1 times with a remainder of 679.
Record the quotient 1 as the next digit in the result. 
Result so far: 83219.631
If we subtract 991 from 1670, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 12:
6790 divided by 991 is 6 with a remainder of 844.
Record the quotient 6 as the next digit in the result. 
Result so far: 83219.6316
If we subtract 5946 from 6790, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 13:
If we divide 8440 by 991, we get 8 and a remainder of 512.
Use 8 as the next digit of our solution. 
Result so far: 83219.63168
Subtract 7928 from 8440 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 14:
The number 991 fits into 5120 5 times, leaving a remainder of 165.
The next digit of our result is 5. 
Result so far: 83219.631685
If we subtract 4955 from 5120, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 15:
991 can be fit into 1650 1 times, resulting in a remainder of 659.
The next digit of our result is 1. 
Result so far: 83219.6316851
Deduct 991 from 1650 and we're left with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Moving on to step 16:
991 goes into 6590 6 times with a remainder of 644.
The number 6 becomes the next digit in our result. 
Result so far: 83219.63168516
Deduct 5946 from 6590 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The final outcome is 83219.63168516, with a leftover of 6.44e-07.
