We look at the division of 710535 by 21 
We want to figure out the number of times 710535 can be divided by 21.

Going ahead to step 1:
21 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 21

Moving on to step 2:
When dividing 71 by 21, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 71 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 21

Advancing to step 3:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtract 63 from 80 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 21

On to step 4:
175 divided by 21 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
Subtract 168 from 175 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 21

Let's proceed to step 5:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3383.0
If we subtract 63 from 73, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 21

Going ahead to step 6:
105 divided by 21 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 33835.0
The remainder is 0 after subtracting 105 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33835.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33835.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 33835.0 with a remaining 0.0.
