750575 divided by 21 
We want to divide 750575 by 21.

Step 1:
21 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 21

Going ahead to step 2:
When dividing 75 by 21, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 12 after subtracting 63 from 75.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 21

Going ahead to step 3:
120 divided by 21 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 105 from 120, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 21

Going ahead to step 4:
155 divided by 21 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 357.0
If we take 147 away from 155, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 21

Moving on to step 5:
21 goes into 87 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 3574.0
If we subtract 84 from 87, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 21

Going ahead to step 6:
21 can be fit into 35 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 35741.0
Deduct 21 from 35 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.
Record the quotient 6 as the next digit in the result. 
Result so far: 35741.6
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.

Going ahead to step 8:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 35741.66
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.

After the division, we end up with 35741.66 and a remainder of 0.014.
