We divide 12512815 by 220
Let's see how many times 220 fits into 12512815.

Moving on to step 1:
220 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 220

Let's proceed to step 2:
220 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 220

Step 3:
220 goes into 125 0 times with a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 220

Moving on to step 4:
220 can be fit into 1251 5 times, resulting in a remainder of 151.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 1100 from 1251 and we're left with 151.
Grab the next digit (2) from the dividend, add it to 151, then carry on: 1512 / 220

Moving on to step 5:
The number 220 fits into 1512 6 times, leaving a remainder of 192.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 1320 from 1512, we get 192.
Include the next digit (8) from the dividend after 192, then repeat: 1928 / 220

Advancing to step 6:
If we divide 1928 by 220, we get 8 and a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 568.0
If we subtract 1760 from 1928, we get 168.
Append the next digit (1) from the dividend to 168 and continue with: 1681 / 220

On to step 7:
The number 220 fits into 1681 7 times, leaving a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 5687.0
Deduct 1540 from 1681 and we're left with 141.
Append the next digit (5) from the dividend to 141 and continue with: 1415 / 220

Going ahead to step 8:
1415 divided by 220 is 6 with a remainder of 95.
Write down 6 as next digit of the result. 
Result so far: 56876.0
Subtract 1320 from 1415 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
950 divided by 220 is 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 56876.4
If we subtract 880 from 950, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
220 goes into 700 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 56876.43
Subtract 660 from 700 to 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.

Moving on to step 11:
400 divided by 220 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 56876.431
If we take 220 away from 400, we end up with 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 12:
The number 220 fits into 1800 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 56876.4318
Subtract 1760 from 1800 to 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.

Moving on to step 13:
220 goes into 400 1 times with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 56876.43181
Deduct 220 from 400 and we're left with 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.
Write down 8 as next digit of the result. 
Result so far: 56876.431818
Subtract 1760 from 1800 to 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.

Advancing to step 15:
The number 220 fits into 400 1 times, leaving a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 56876.4318181
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.

On to step 16:
If we divide 1800 by 220, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 56876.43181818
Subtract 1760 from 1800 to 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.

After the division, we end up with 56876.43181818 and a remainder of 4e-08.
