We look at the division of 21049096 by 525 
Let's see how many times 525 fits into 21049096.

Advancing to step 1:
525 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 / 525

Advancing to step 2:
21 divided by 525 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 525

Let's proceed to step 3:
210 divided by 525 is 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Take the next digit (4) from the dividend and append it to 210, then repeat: 2104 / 525

On to step 4:
When dividing 2104 by 525, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2100 from 2104 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 525

Moving on to step 5:
49 divided by 525 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 49, we get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 525

Going ahead to step 6:
525 can be fit into 490 0 times, resulting in a remainder of 490.
The next digit of our result is 0. 
Result so far: 400.0
The remainder is 490 after subtracting 0 from 490.
Grab the next digit (9) from the dividend, add it to 490, then carry on: 4909 / 525

Going ahead to step 7:
4909 divided by 525 is 9 with a remainder of 184.
Use 9 as the next digit of our solution. 
Result so far: 4009.0
If we take 4725 away from 4909, we end up with 184.
Take the next digit (6) from the dividend and append it to 184, then repeat: 1846 / 525

Step 8:
525 can be fit into 1846 3 times, resulting in a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 40093.0
Subtracting 1575 from 1846 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 9:
If we divide 2710 by 525, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 40093.5
The remainder is 85 after subtracting 2625 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
850 divided by 525 is 1 with a remainder of 325.
Put 1 as the next digit of the answer. 
Result so far: 40093.51
The remainder is 325 after subtracting 525 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
When dividing 3250 by 525, we get 6 with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 40093.516
If we take 3150 away from 3250, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
525 can be fit into 1000 1 times, resulting in a remainder of 475.
Record the quotient 1 as the next digit in the result. 
Result so far: 40093.5161
If we subtract 525 from 1000, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 13:
When dividing 4750 by 525, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 40093.51619
Subtract 4725 from 4750 to get 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 14:
The number 525 fits into 250 0 times, leaving a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 40093.51619
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
When dividing 2500 by 525, we get 4 with a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 40093.5161904
Subtracting 2100 from 2500 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
525 goes into 4000 7 times with a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 40093.51619047
If we take 3675 away from 4000, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 40093.51619047 and a remainder of 3.25e-07.
