We divide 21174174 by 525
Let's see how many times 525 fits into 21174174.

Advancing to step 1:
525 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 525

Advancing to step 2:
The number 525 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 525

Moving on to step 3:
525 can be fit into 211 0 times, resulting in a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 525

On to step 4:
The number 525 fits into 2117 4 times, leaving a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2100 from 2117 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 525

Step 5:
The number 525 fits into 174 0 times, leaving a remainder of 174.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 174 to get 174.
Include the next digit (1) from the dividend after 174, then repeat: 1741 / 525

Step 6:
525 goes into 1741 3 times with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 403.0
Deduct 1575 from 1741 and we're left with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 525

Let's proceed to step 7:
525 can be fit into 1667 3 times, resulting in a remainder of 92.
Use 3 as the next digit of our solution. 
Result so far: 4033.0
If we subtract 1575 from 1667, we get 92.
Take the next digit (4) from the dividend and append it to 92, then repeat: 924 / 525

Going ahead to step 8:
525 can be fit into 924 1 times, resulting in a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 40331.0
If we subtract 525 from 924, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 9:
When dividing 3990 by 525, we get 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 40331.7
If we subtract 3675 from 3990, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 10:
If we divide 3150 by 525, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 40331.76
Subtract 3150 from 3150 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 525, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40331.76
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 525 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40331.76
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 40331.76, with a leftover of 0.0.
