440631 divided by 51 
We want to figure out the number of times 440631 can be divided by 51.

On to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 51

Going ahead to step 2:
51 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 51

On to step 3:
51 goes into 440 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8.0
If we take 408 away from 440, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 51

Moving on to step 4:
51 can be fit into 326 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 306 from 326, we get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 51

Step 5:
When dividing 203 by 51, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 863.0
Subtracting 153 from 203 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 51

Let's proceed to step 6:
51 can be fit into 501 9 times, resulting in a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 8639.0
Subtracting 459 from 501 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.

Step 7:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8639.8
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 51 fits into 120 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 8639.82
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
If we divide 180 by 51, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 8639.823
Subtract 153 from 180 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
When dividing 270 by 51, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8639.8235
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
51 goes into 150 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 8639.82352
Subtracting 102 from 150 leaves us 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.

Step 12:
If we divide 480 by 51, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 8639.823529
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
51 goes into 210 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 8639.8235294
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 8639.82352941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 8639.82352941 with a balance of 9e-09.
