Let's divide 18242000 by 21
We want to figure out the number of times 18242000 can be divided by 21.

On to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 21

Advancing to step 2:
If we divide 18 by 21, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 21

On to step 3:
21 goes into 182 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 168 from 182 leaves us with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 21

Going ahead to step 4:
21 goes into 144 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 126 from 144 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 21

On to step 5:
182 divided by 21 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 868.0
Subtract 168 from 182 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 21

Advancing to step 6:
When dividing 140 by 21, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 8686.0
If we take 126 away from 140, we end up with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 21

On to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 86866.0
If we take 126 away from 140, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 21

Moving on to step 8:
21 goes into 140 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 868666.0
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 21 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 868666.6
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
21 goes into 140 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 868666.66
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 868666.66 with a balance of 0.014.
