242002 divided by 21 
We want to divide 242002 by 21.

Advancing to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 21

On to step 2:
When dividing 24 by 21, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 21 from 24, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 21

Let's proceed to step 3:
When dividing 32 by 21, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 11 after subtracting 21 from 32.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 21

Moving on to step 4:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 105 from 110 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 21

Advancing to step 5:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
The remainder is 8 after subtracting 42 from 50.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

Advancing to step 6:
The number 21 fits into 82 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 11523.0
The remainder is 19 after subtracting 63 from 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 11523.9
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11523.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 11523.904
Subtracting 84 from 100 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.

Let's proceed to step 10:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 11523.9047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 11523.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 11523.904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 11523.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 11523.9047619
Subtracting 0 from 10 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.

The final outcome is 11523.9047619, with a leftover of 1e-08.
