We look at the division of 721253 by 35 
We're looking to find how many times 35 goes into 721253.

On to step 1:
35 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 35

Advancing to step 2:
The number 35 fits into 72 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 2 after subtracting 70 from 72.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 35

Let's proceed to step 3:
If we divide 21 by 35, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 21, we get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 35

On to step 4:
When dividing 212 by 35, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtract 210 from 212 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 35

Going ahead to step 5:
The number 35 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 2060.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 35

Step 6:
253 divided by 35 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 20607.0
If we subtract 245 from 253, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
35 can be fit into 80 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 20607.2
Deduct 70 from 80 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 35, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 20607.22
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 20607.22 and a remainder of 0.03.
