100352 divided by 21 
Our goal is to divide 100352 by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 21

Step 2:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 21

On to step 3:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 16 after subtracting 84 from 100.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 21

Advancing to step 4:
The number 21 fits into 163 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 147 away from 163, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 21

Step 5:
21 can be fit into 165 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 477.0
If we subtract 147 from 165, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 21

On to step 6:
The number 21 fits into 182 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 4778.0
Deduct 168 from 182 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.

Let's proceed to step 7:
21 goes into 140 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 4778.6
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
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: 4778.66
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.

After the division, we end up with 4778.66 and a remainder of 0.014.
