Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 972

Step 2:
When dividing 53 by 972, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 972

Step 3:
538 divided by 972 is 0 with a remainder of 538.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 538 leaves us with 538.
Bring next digit (0) of the dividend behind the 538 and repeat the process: 5380 / 972

Step 4:
972 goes into 5380 5 times with a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 520 after subtracting 4860 from 5380.
Fetch the next digit (3) from the dividend, attach it to 520 and continue: 5203 / 972

Going ahead to step 5:
5203 divided by 972 is 5 with a remainder of 343.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 4860 from 5203 to get 343.
Fetch the next digit (0) from the dividend, attach it to 343 and continue: 3430 / 972

Advancing to step 6:
The number 972 fits into 3430 3 times, leaving a remainder of 514.
The next digit of our result is 3. 
Result so far: 553.0
Subtracting 2916 from 3430 leaves us with 514.
Grab the next digit (0) from the dividend, add it to 514, then carry on: 5140 / 972

972 goes into 5140 5 times with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 5535.0
Subtract 4860 from 5140 to get 280.
Include the next digit (9) from the dividend after 280, then repeat: 2809 / 972

Moving on to step 8:
The number 972 fits into 2809 2 times, leaving a remainder of 865.
Write down 2 as next digit of the result.

Subtracting 1944 from 2809 leaves us with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Moving on to step 9:
The number 972 fits into 8650 8 times, leaving a remainder of 874.
Record the quotient 8 as the next digit in the result. 
Result so far: 55352.8
Deduct 7776 from 8650 and we're left with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Moving on to step 10:
8740 divided by 972 is 8 with a remainder of 964.
Put 8 as the next digit of the answer. 
Result so far: 55352.88
Deduct 7776 from 8740 and we're left with 964.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9640, and continue the process.
