210421 divided by 24 
We want to figure out the number of times 210421 can be divided by 24.

Let's proceed to step 1:
When dividing 2 by 24, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 24

Let's proceed to step 2:
The number 24 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 24

Advancing to step 3:
24 goes into 210 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 192 from 210 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 24

On to step 4:
The number 24 fits into 184 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 168 from 184, we get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 24

Step 5:
The number 24 fits into 162 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 876.0
Subtracting 144 from 162 leaves us with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 24

Advancing to step 6:
24 goes into 181 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 8767.0
The remainder is 13 after subtracting 168 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
24 can be fit into 130 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8767.5
Subtracting 120 from 130 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 24, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 8767.54
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 24, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 8767.541
Subtracting 24 from 40 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
The number 24 fits into 160 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 8767.5416
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8767.54166
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 8767.54166 and a remainder of 1.6e-05.
