Let's divide 77808870 by 220
We want to divide 77808870 by 220.

On to step 1:
When dividing 7 by 220, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 220

On to step 2:
If we divide 77 by 220, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 220

Let's proceed to step 3:
220 can be fit into 778 3 times, resulting in a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 660 from 778, we get 118.
Fetch the next digit (0) from the dividend, attach it to 118 and continue: 1180 / 220

Moving on to step 4:
The number 220 fits into 1180 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 1100 from 1180 and we're left with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 220

Let's proceed to step 5:
220 goes into 808 3 times with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
If we subtract 660 from 808, we get 148.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 220

Going ahead to step 6:
1488 divided by 220 is 6 with a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 3536.0
Subtracting 1320 from 1488 leaves us with 168.
Append the next digit (7) from the dividend to 168 and continue with: 1687 / 220

On to step 7:
When dividing 1687 by 220, we get 7 with a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 35367.0
Subtracting 1540 from 1687 leaves us with 147.
Grab the next digit (0) from the dividend, add it to 147, then carry on: 1470 / 220

Going ahead to step 8:
When dividing 1470 by 220, we get 6 with a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 353676.0
Deduct 1320 from 1470 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
If we divide 1500 by 220, we get 6 and a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 353676.6
Subtract 1320 from 1500 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
220 can be fit into 1800 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 353676.68
The remainder is 40 after subtracting 1760 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
220 goes into 400 1 times with a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 353676.681
If we subtract 220 from 400, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
220 goes into 1800 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 353676.6818
The remainder is 40 after subtracting 1760 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
220 can be fit into 400 1 times, resulting in a remainder of 180.
The next digit of our result is 1. 
Result so far: 353676.68181
Subtract 220 from 400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
220 can be fit into 1800 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 353676.681818
The remainder is 40 after subtracting 1760 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
When dividing 400 by 220, we get 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 353676.6818181
Subtract 220 from 400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
220 can be fit into 1800 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 353676.68181818
If we subtract 1760 from 1800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 353676.68181818 with a balance of 4e-08.
