We divide 21053252 by 23
We want to divide 21053252 by 23.

Step 1:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 23

On to step 2:
If we divide 21 by 23, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 23

Advancing to step 3:
23 goes into 210 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 207 away from 210, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 23

Going ahead to step 4:
If we divide 35 by 23, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 91.0
The remainder is 12 after subtracting 23 from 35.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 23

Going ahead to step 5:
The number 23 fits into 123 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 915.0
The remainder is 8 after subtracting 115 from 123.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 23

Moving on to step 6:
23 goes into 82 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 9153.0
If we subtract 69 from 82, we get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 23

On to step 7:
23 goes into 135 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 91535.0
If we take 115 away from 135, we end up with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 23

Let's proceed to step 8:
202 divided by 23 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 915358.0
Subtracting 184 from 202 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 915358.7
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
If we divide 190 by 23, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 915358.78
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 915358.782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 915358.7826
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
23 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 915358.7826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
23 goes into 200 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 915358.782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
23 goes into 160 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 915358.7826086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
When dividing 220 by 23, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 915358.78260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 915358.78260869 with a balance of 1.3e-08.
