We look at the division of 228712 by 20 
We want to divide 228712 by 20.

Step 1:
2 divided by 20 is 0 with 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 (2) from the dividend, add it to 2, then carry on: 22 / 20

Advancing to step 2:
22 divided by 20 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 22, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

Moving on to step 3:
The number 20 fits into 28 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 20 from 28 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 20

On to step 4:
87 divided by 20 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we take 80 away from 87, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 20

Step 5:
71 divided by 20 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 1143.0
Subtracting 60 from 71 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 20

Step 6:
When dividing 112 by 20, we get 5 with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 11435.0
Subtracting 100 from 112 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 20, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 11435.6
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11435.6
The remainder is 0 after subtracting 0 from 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 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: 11435.6
Deduct 0 from 0 and we're left 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.

The final result is 11435.6 with a remainder of 0.0.
