We're dividing 21788453 by 915 
Our goal is to divide 21788453 by 915.

Step 1:
915 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
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 / 915

On to step 2:
When dividing 21 by 915, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 915

Going ahead to step 3:
The number 915 fits into 217 0 times, leaving a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Fetch the next digit (8) from the dividend, attach it to 217 and continue: 2178 / 915

On to step 4:
915 can be fit into 2178 2 times, resulting in a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1830 from 2178, we get 348.
Include the next digit (8) from the dividend after 348, then repeat: 3488 / 915

On to step 5:
If we divide 3488 by 915, we get 3 and a remainder of 743.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 2745 from 3488 leaves us with 743.
Fetch the next digit (4) from the dividend, attach it to 743 and continue: 7434 / 915

Going ahead to step 6:
If we divide 7434 by 915, we get 8 and a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Subtract 7320 from 7434 to get 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 915

Going ahead to step 7:
915 can be fit into 1145 1 times, resulting in a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 2381.0
Subtract 915 from 1145 to get 230.
Grab the next digit (3) from the dividend, add it to 230, then carry on: 2303 / 915

Let's proceed to step 8:
If we divide 2303 by 915, we get 2 and a remainder of 473.
The number 2 becomes the next digit in our result. 
Result so far: 23812.0
Subtract 1830 from 2303 to get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 9:
4730 divided by 915 is 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 23812.5
The remainder is 155 after subtracting 4575 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 10:
1550 divided by 915 is 1 with a remainder of 635.
The next digit of our result is 1. 
Result so far: 23812.51
If we take 915 away from 1550, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 11:
If we divide 6350 by 915, we get 6 and a remainder of 860.
Record the quotient 6 as the next digit in the result. 
Result so far: 23812.516
Subtract 5490 from 6350 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Step 12:
8600 divided by 915 is 9 with a remainder of 365.
Write down 9 as next digit of the result. 
Result so far: 23812.5169
Subtract 8235 from 8600 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 13:
915 goes into 3650 3 times with a remainder of 905.
Use 3 as the next digit of our solution. 
Result so far: 23812.51693
If we take 2745 away from 3650, we end up with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Moving on to step 14:
9050 divided by 915 is 9 with a remainder of 815.
The next digit of our result is 9. 
Result so far: 23812.516939
Deduct 8235 from 9050 and we're left with 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

On to step 15:
915 can be fit into 8150 8 times, resulting in a remainder of 830.
The next digit of our result is 8. 
Result so far: 23812.5169398
If we subtract 7320 from 8150, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 16:
If we divide 8300 by 915, we get 9 and a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 23812.51693989
Subtracting 8235 from 8300 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 23812.51693989 with a balance of 6.5e-08.
