We divide 439775 by 51
We want to divide 439775 by 51.

On to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 51

Step 2:
43 divided by 51 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 51

Going ahead to step 3:
51 can be fit into 439 8 times, resulting in a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 408 away from 439, we end up with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 51

Step 4:
51 can be fit into 317 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 86.0
The remainder is 11 after subtracting 306 from 317.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 51

Moving on to step 5:
117 divided by 51 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
If we take 102 away from 117, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 51

Moving on to step 6:
51 goes into 155 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8623.0
The remainder is 2 after subtracting 153 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8623.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 51, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 8623.03
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
If we divide 470 by 51, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 8623.039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8623.0392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 51 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 8623.03921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
The number 51 fits into 290 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8623.039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
When dividing 350 by 51, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 8623.0392156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
440 divided by 51 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8623.03921568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 8623.03921568, with a leftover of 3.2e-08.
