We look at the division of 20281138 by 815 
Our goal is to divide 20281138 by 815.

Moving on to step 1:
815 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 815

Step 2:
The number 815 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 815

Let's proceed to step 3:
202 divided by 815 is 0 with a remainder of 202.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 202 after subtracting 0 from 202.
Append the next digit (8) from the dividend to 202 and continue with: 2028 / 815

On to step 4:
If we divide 2028 by 815, we get 2 and a remainder of 398.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1630 away from 2028, we end up with 398.
Append the next digit (1) from the dividend to 398 and continue with: 3981 / 815

Moving on to step 5:
When dividing 3981 by 815, we get 4 with a remainder of 721.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 3260 from 3981 leaves us with 721.
Include the next digit (1) from the dividend after 721, then repeat: 7211 / 815

Moving on to step 6:
When dividing 7211 by 815, we get 8 with a remainder of 691.
Put 8 as the next digit of the answer. 
Result so far: 248.0
If we take 6520 away from 7211, we end up with 691.
Fetch the next digit (3) from the dividend, attach it to 691 and continue: 6913 / 815

Step 7:
6913 divided by 815 is 8 with a remainder of 393.
Use 8 as the next digit of our solution. 
Result so far: 2488.0
Subtracting 6520 from 6913 leaves us with 393.
Grab the next digit (8) from the dividend, add it to 393, then carry on: 3938 / 815

Let's proceed to step 8:
3938 divided by 815 is 4 with a remainder of 678.
Record the quotient 4 as the next digit in the result. 
Result so far: 24884.0
If we take 3260 away from 3938, we end up with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Advancing to step 9:
6780 divided by 815 is 8 with a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 24884.8
Subtracting 6520 from 6780 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
815 goes into 2600 3 times with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 24884.83
If we take 2445 away from 2600, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 11:
If we divide 1550 by 815, we get 1 and a remainder of 735.
Write down 1 as next digit of the result. 
Result so far: 24884.831
Subtracting 815 from 1550 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 12:
815 goes into 7350 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 24884.8319
Deduct 7335 from 7350 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
150 divided by 815 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 24884.8319
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
The number 815 fits into 1500 1 times, leaving a remainder of 685.
Put 1 as the next digit of the answer. 
Result so far: 24884.831901
If we subtract 815 from 1500, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 15:
When dividing 6850 by 815, we get 8 with a remainder of 330.
Record the quotient 8 as the next digit in the result. 
Result so far: 24884.8319018
The remainder is 330 after subtracting 6520 from 6850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
815 can be fit into 3300 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 24884.83190184
Subtract 3260 from 3300 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.

Our division results in 24884.83190184 with a remaining 4e-08.
