We divide 745535 by 21
Let's see how many times 21 fits into 745535.

Let's proceed to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 21

Let's proceed to step 2:
If we divide 74 by 21, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 63 from 74 leaves us with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 21

Advancing to step 3:
115 divided by 21 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 105 from 115, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 21

Advancing to step 4:
21 goes into 105 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
Subtracting 105 from 105 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

Moving on to step 5:
If we divide 3 by 21, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 3550.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 21

Let's proceed to step 6:
35 divided by 21 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 35501.0
Subtracting 21 from 35 leaves us 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 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 35501.6
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.

On to step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 35501.66
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.

After the division, we end up with 35501.66 and a remainder of 0.014.
