Let's divide 179525 by 21
We want to figure out the number of times 179525 can be divided by 21.

On to step 1:
1 divided by 21 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 21

Let's proceed to step 2:
21 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 21

Advancing to step 3:
21 can be fit into 179 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 168 from 179 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 21

Let's proceed to step 4:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 105 from 115 leaves us with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 21

Step 5:
102 divided by 21 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Subtracting 84 from 102 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 21

Advancing to step 6:
If we divide 185 by 21, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8548.0
Subtracting 168 from 185 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8548.8
Subtracting 168 from 170 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.

Advancing to step 8:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8548.8
Subtract 0 from 20 to 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.

On to step 9:
If we divide 200 by 21, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8548.809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8548.8095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8548.80952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 8548.809523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
21 goes into 170 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8548.8095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8548.8095238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 8548.8095238, with a leftover of 2e-08.
