21570456 divided by 220 
We're looking to find how many times 220 goes into 21570456.

Advancing to step 1:
220 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 220

On to step 2:
If we divide 21 by 220, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 220

Advancing to step 3:
The number 220 fits into 215 0 times, leaving a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Bring next digit (7) of the dividend behind the 215 and repeat the process: 2157 / 220

Moving on to step 4:
The number 220 fits into 2157 9 times, leaving a remainder of 177.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 1980 from 2157 and we're left with 177.
Fetch the next digit (0) from the dividend, attach it to 177 and continue: 1770 / 220

Advancing to step 5:
220 can be fit into 1770 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 1760 away from 1770, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 220

On to step 6:
When dividing 104 by 220, we get 0 with a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 980.0
Deduct 0 from 104 and we're left with 104.
Include the next digit (5) from the dividend after 104, then repeat: 1045 / 220

Going ahead to step 7:
1045 divided by 220 is 4 with a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 9804.0
The remainder is 165 after subtracting 880 from 1045.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 220

Step 8:
220 can be fit into 1656 7 times, resulting in a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 98047.0
The remainder is 116 after subtracting 1540 from 1656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 9:
The number 220 fits into 1160 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 98047.5
If we take 1100 away from 1160, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
220 can be fit into 600 2 times, resulting in a remainder of 160.
The next digit of our result is 2. 
Result so far: 98047.52
Subtract 440 from 600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
220 goes into 1600 7 times with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 98047.527
The remainder is 60 after subtracting 1540 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
220 goes into 600 2 times with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 98047.5272
Deduct 440 from 600 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
The number 220 fits into 1600 7 times, leaving a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 98047.52727
If we take 1540 away from 1600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
When dividing 600 by 220, we get 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 98047.527272
The remainder is 160 after subtracting 440 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
The number 220 fits into 1600 7 times, leaving a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 98047.5272727
If we subtract 1540 from 1600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
The number 220 fits into 600 2 times, leaving a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 98047.52727272
If we take 440 away from 600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 98047.52727272 with a balance of 1.6e-07.
