We look at the division of 210521 by 24 
We want to divide 210521 by 24.

Let's proceed to step 1:
When dividing 2 by 24, we get 0 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 24

Going ahead to step 2:
The number 24 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 24

Moving on to step 3:
The number 24 fits into 210 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 192 from 210, we get 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 24

Moving on to step 4:
185 divided by 24 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 168 away from 185, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 24

Step 5:
24 can be fit into 172 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 877.0
Subtract 168 from 172 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 24

Moving on to step 6:
When dividing 41 by 24, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 8771.0
Deduct 24 from 41 and we're left 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.

Moving on to step 7:
170 divided by 24 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 8771.7
Deduct 168 from 170 and we're left 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:
24 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8771.7
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.

Advancing to step 9:
24 can be fit into 200 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8771.708
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 24 fits into 80 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 8771.7083
Subtracting 72 from 80 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.

Let's proceed to step 11:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 8771.70833
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 8771.70833, and the remainder is 8e-06.
