We look at the division of 253241 by 20 
We want to divide 253241 by 20.

Moving on to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 20

On to step 2:
If we divide 25 by 20, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 20 from 25.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 20

Going ahead to step 3:
20 goes into 53 2 times with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 13 after subtracting 40 from 53.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 20

Let's proceed to step 4:
If we divide 132 by 20, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 126.0
Deduct 120 from 132 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 20

Advancing to step 5:
When dividing 124 by 20, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1266.0
If we subtract 120 from 124, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 20

Let's proceed to step 6:
41 divided by 20 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12662.0
Subtracting 40 from 41 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
20 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12662.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12662.05
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12662.05
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12662.05
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12662.05 and a remainder of 0.0.
