Let's divide 767200 by 21
Our goal is to divide 767200 by 21.

On to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 21

Going ahead to step 2:
When dividing 76 by 21, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 63 from 76 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 21

Step 3:
137 divided by 21 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 126 from 137 to get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 21

Moving on to step 4:
21 goes into 112 5 times with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 365.0
If we subtract 105 from 112, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

On to step 5:
If we divide 70 by 21, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3653.0
Subtract 63 from 70 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 21

Going ahead to step 6:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 36533.0
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
21 goes into 70 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 36533.3
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 36533.33
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 36533.33 and a remainder of 0.007.
