We divide 21353250 by 220
We're looking to find how many times 220 goes into 21353250.

Going ahead to step 1:
220 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 220

Going ahead to step 2:
21 divided by 220 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 220

Advancing to step 3:
213 divided by 220 is 0 with a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Append the next digit (5) from the dividend to 213 and continue with: 2135 / 220

Let's proceed to step 4:
220 can be fit into 2135 9 times, resulting in a remainder of 155.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 1980 from 2135 to get 155.
Include the next digit (3) from the dividend after 155, then repeat: 1553 / 220

Step 5:
1553 divided by 220 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 97.0
If we take 1540 away from 1553, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 220

Let's proceed to step 6:
132 divided by 220 is 0 with a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 970.0
Subtracting 0 from 132 leaves us with 132.
Include the next digit (5) from the dividend after 132, then repeat: 1325 / 220

Let's proceed to step 7:
1325 divided by 220 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 9706.0
If we subtract 1320 from 1325, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 220

Let's proceed to step 8:
220 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 97060.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
When dividing 500 by 220, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 97060.2
The remainder is 60 after subtracting 440 from 500.
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 10:
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: 97060.22
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.

The final result is 97060.22 with a remainder of 0.16.
