Let's divide 44451 by 51
We want to divide 44451 by 51.

On to step 1:
51 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 51

On to step 2:
The number 51 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 51

Moving on to step 3:
51 can be fit into 444 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 408 from 444 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 51

Moving on to step 4:
51 goes into 365 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 357 from 365, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Step 5:
81 divided by 51 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 871.0
Deduct 51 from 81 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 6:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 871.5
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 871.58
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 871.588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 871.588 with a remaining 0.0012.
