If we divide 4722 by 981, we get 4 and a remainder of 798.
The next digit of our result is 4. 
Result so far: 564.0
Subtracting 3924 from 4722 leaves us with 798.
Fetch the next digit (3) from the dividend, attach it to 798 and continue: 7983 / 981

Let's proceed to step 7:
If we divide 7983 by 981, we get 8 and a remainder of 135.
The number 8 becomes the next digit in our result. 
Result so far: 5648.0
Deduct 7848 from 7983 and we're left with 135.
Fetch the next digit (3) from the dividend, attach it to 135 and continue: 1353 / 981

Advancing to step 8:
The number 981 fits into 1353 1 times, leaving a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 56481.0
The remainder is 372 after subtracting 981 from 1353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 9:
981 goes into 3720 3 times with a remainder of 777.
Write down 3 as next digit of the result. 
Result so far: 56481.3
Deduct 2943 from 3720 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 10:
When dividing 7770 by 981, we get 7 with a remainder of 903.
Write down 7 as next digit of the result. 
Result so far: 56481.37
The remainder is 903 after subtracting 6867 from 7770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9030, and continue the process.

On to step 11:
When dividing 9030 by 981, we get 9 with a remainder of 201.
Put 9 as the next digit of the answer. 
Result so far: 56481.379
Subtracting 8829 from 9030 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 12:
2010 divided by 981 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 56481.3792
Deduct 1962 from 2010 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
981 goes into 480 0 times with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 56481.3792
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
981 can be fit into 4800 4 times, resulting in a remainder of 876.
The next digit of our result is 4. 
Result so far: 56481.379204
If we take 3924 away from 4800, we end up with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Moving on to step 15:
8760 divided by 981 is 8 with a remainder of 912.
The number 8 becomes the next digit in our result. 
Result so far: 56481.3792048
Subtract 7848 from 8760 to get 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Going ahead to step 16:
The number 981 fits into 9120 9 times, leaving a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 56481.37920489
The remainder is 291 after subtracting 8829 from 9120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The final result is 56481.37920489 with a remainder of 2.91e-07.
