We divide 80879155 by 647
We want to divide 80879155 by 647.

Step 1:
647 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 647

Advancing to step 2:
When dividing 80 by 647, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 647

Step 3:
808 divided by 647 is 1 with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 647 from 808 to get 161.
Append the next digit (7) from the dividend to 161 and continue with: 1617 / 647

Going ahead to step 4:
When dividing 1617 by 647, we get 2 with a remainder of 323.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1294 from 1617, we get 323.
Append the next digit (9) from the dividend to 323 and continue with: 3239 / 647

On to step 5:
647 goes into 3239 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 3235 from 3239 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 647

On to step 6:
41 divided by 647 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 1250.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 647

Let's proceed to step 7:
415 divided by 647 is 0 with a remainder of 415.
Record the quotient 0 as the next digit in the result. 
Result so far: 12500.0
If we subtract 0 from 415, we get 415.
Bring next digit (5) of the dividend behind the 415 and repeat the process: 4155 / 647

Moving on to step 8:
647 can be fit into 4155 6 times, resulting in a remainder of 273.
The number 6 becomes the next digit in our result. 
Result so far: 125006.0
The remainder is 273 after subtracting 3882 from 4155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 9:
The number 647 fits into 2730 4 times, leaving a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 125006.4
Subtracting 2588 from 2730 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 10:
When dividing 1420 by 647, we get 2 with a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 125006.42
The remainder is 126 after subtracting 1294 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 11:
The number 647 fits into 1260 1 times, leaving a remainder of 613.
Put 1 as the next digit of the answer. 
Result so far: 125006.421
If we subtract 647 from 1260, we get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Step 12:
The number 647 fits into 6130 9 times, leaving a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 125006.4219
If we subtract 5823 from 6130, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 13:
3070 divided by 647 is 4 with a remainder of 482.
Record the quotient 4 as the next digit in the result. 
Result so far: 125006.42194
If we subtract 2588 from 3070, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 14:
4820 divided by 647 is 7 with a remainder of 291.
Use 7 as the next digit of our solution. 
Result so far: 125006.421947
Subtracting 4529 from 4820 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 15:
647 goes into 2910 4 times with a remainder of 322.
Use 4 as the next digit of our solution. 
Result so far: 125006.4219474
The remainder is 322 after subtracting 2588 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 16:
The number 647 fits into 3220 4 times, leaving a remainder of 632.
The number 4 becomes the next digit in our result. 
Result so far: 125006.42194744
The remainder is 632 after subtracting 2588 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

In conclusion, the division gives 125006.42194744 with a balance of 6.32e-07.
