We look at the division of 54879885 by 972 
Let's see how many times 972 fits into 54879885.

Moving on to step 1:
When dividing 5 by 972, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 972

On to step 2:
972 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 972

Going ahead to step 3:
The number 972 fits into 548 0 times, leaving a remainder of 548.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 548, we end up with 548.
Append the next digit (7) from the dividend to 548 and continue with: 5487 / 972

Moving on to step 4:
The number 972 fits into 5487 5 times, leaving a remainder of 627.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4860 away from 5487, we end up with 627.
Fetch the next digit (9) from the dividend, attach it to 627 and continue: 6279 / 972

Moving on to step 5:
972 can be fit into 6279 6 times, resulting in a remainder of 447.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 5832 from 6279 to get 447.
Append the next digit (8) from the dividend to 447 and continue with: 4478 / 972

Advancing to step 6:
972 can be fit into 4478 4 times, resulting in a remainder of 590.
Use 4 as the next digit of our solution. 
Result so far: 564.0
If we subtract 3888 from 4478, we get 590.
Grab the next digit (8) from the dividend, add it to 590, then carry on: 5908 / 972

On to step 7:
When dividing 5908 by 972, we get 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 5646.0
If we subtract 5832 from 5908, we get 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 972

Step 8:
If we divide 765 by 972, we get 0 and a remainder of 765.
Write down 0 as next digit of the result. 
Result so far: 56460.0
The remainder is 765 after subtracting 0 from 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 9:
7650 divided by 972 is 7 with a remainder of 846.
Put 7 as the next digit of the answer. 
Result so far: 56460.7
If we subtract 6804 from 7650, we get 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Let's proceed to step 10:
If we divide 8460 by 972, we get 8 and a remainder of 684.
The next digit of our result is 8. 
Result so far: 56460.78
Subtracting 7776 from 8460 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Let's proceed to step 11:
6840 divided by 972 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 56460.787
Subtract 6804 from 6840 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 972, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 56460.787
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
972 goes into 3600 3 times with a remainder of 684.
Use 3 as the next digit of our solution. 
Result so far: 56460.78703
If we take 2916 away from 3600, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 14:
If we divide 6840 by 972, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 56460.787037
If we subtract 6804 from 6840, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
972 can be fit into 360 0 times, resulting in a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 56460.787037
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
3600 divided by 972 is 3 with a remainder of 684.
Write down 3 as next digit of the result. 
Result so far: 56460.78703703
Subtract 2916 from 3600 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

After the division, we end up with 56460.78703703 and a remainder of 6.84e-07.
