Let's divide 721002 by 53
We want to figure out the number of times 721002 can be divided by 53.

Going ahead to step 1:
The number 53 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 53

On to step 2:
The number 53 fits into 72 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 53 from 72 leaves us with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 53

Advancing to step 3:
When dividing 191 by 53, we get 3 with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 159 from 191, we get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 53

Moving on to step 4:
53 goes into 320 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we subtract 318 from 320, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 53

Step 5:
53 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1360.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 53

Advancing to step 6:
53 can be fit into 202 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 13603.0
The remainder is 43 after subtracting 159 from 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
53 can be fit into 430 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 13603.8
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
53 can be fit into 60 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 13603.81
If we subtract 53 from 60, 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.

Step 9:
53 can be fit into 70 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 13603.811
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 13603.811 with a remaining 0.0017.
