We look at the division of 720223 by 53 
We want to figure out the number of times 720223 can be divided by 53.

Going ahead to step 1:
53 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 53

Moving on to step 2:
53 goes into 72 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 53 from 72 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 53

Moving on to step 3:
53 goes into 190 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 159 from 190 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 53

Advancing to step 4:
53 can be fit into 312 5 times, resulting in a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 265 from 312, we get 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 53

Moving on to step 5:
53 goes into 472 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1358.0
Deduct 424 from 472 and we're left with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 53

Moving on to step 6:
If we divide 483 by 53, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 13589.0
Deduct 477 from 483 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
53 goes into 60 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 13589.1
Deduct 53 from 60 and we're left with 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 8:
70 divided by 53 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 13589.11
Subtract 53 from 70 to 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 13589.11 with a remaining 0.017.
