We look at the division of 21521038 by 925 
Let's see how many times 925 fits into 21521038.

Moving on to step 1:
925 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 925

Advancing to step 2:
925 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 925

Going ahead to step 3:
925 goes into 215 0 times with a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Fetch the next digit (2) from the dividend, attach it to 215 and continue: 2152 / 925

Advancing to step 4:
925 goes into 2152 2 times with a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1850 from 2152 to get 302.
Fetch the next digit (1) from the dividend, attach it to 302 and continue: 3021 / 925

Advancing to step 5:
925 can be fit into 3021 3 times, resulting in a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 2775 away from 3021, we end up with 246.
Fetch the next digit (0) from the dividend, attach it to 246 and continue: 2460 / 925

Going ahead to step 6:
When dividing 2460 by 925, we get 2 with a remainder of 610.
Write down 2 as next digit of the result. 
Result so far: 232.0
If we take 1850 away from 2460, we end up with 610.
Bring next digit (3) of the dividend behind the 610 and repeat the process: 6103 / 925

Advancing to step 7:
6103 divided by 925 is 6 with a remainder of 553.
Record the quotient 6 as the next digit in the result. 
Result so far: 2326.0
If we take 5550 away from 6103, we end up with 553.
Append the next digit (8) from the dividend to 553 and continue with: 5538 / 925

Advancing to step 8:
5538 divided by 925 is 5 with a remainder of 913.
Put 5 as the next digit of the answer. 
Result so far: 23265.0
If we take 4625 away from 5538, we end up with 913.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9130, and continue the process.

On to step 9:
925 can be fit into 9130 9 times, resulting in a remainder of 805.
Put 9 as the next digit of the answer. 
Result so far: 23265.9
Subtracting 8325 from 9130 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 10:
925 can be fit into 8050 8 times, resulting in a remainder of 650.
The next digit of our result is 8. 
Result so far: 23265.98
Subtract 7400 from 8050 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 11:
When dividing 6500 by 925, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 23265.987
The remainder is 25 after subtracting 6475 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
925 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 23265.987
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
925 can be fit into 2500 2 times, resulting in a remainder of 650.
The number 2 becomes the next digit in our result. 
Result so far: 23265.98702
If we subtract 1850 from 2500, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 14:
When dividing 6500 by 925, we get 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 23265.987027
Deduct 6475 from 6500 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
925 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 23265.987027
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
The number 925 fits into 2500 2 times, leaving a remainder of 650.
Write down 2 as next digit of the result. 
Result so far: 23265.98702702
Deduct 1850 from 2500 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 23265.98702702, with a leftover of 6.5e-07.
