We're dividing 644881 by 52 
We're looking to find how many times 52 goes into 644881.

Moving on to step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 52

Advancing to step 2:
52 goes into 64 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 52 from 64.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 52

Advancing to step 3:
52 goes into 124 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 104 from 124, we get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 52

Going ahead to step 4:
When dividing 208 by 52, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 124.0
Deduct 208 from 208 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 52

Moving on to step 5:
52 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 1240.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 52

Moving on to step 6:
81 divided by 52 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 12401.0
If we subtract 52 from 81, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
The number 52 fits into 290 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 12401.5
If we subtract 260 from 290, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 52, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 12401.55
If we take 260 away from 300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 12401.55 with a remainder of 0.04.
