We divide 439421 by 51
Let's see how many times 51 fits into 439421.

Moving on to step 1:
4 divided by 51 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 51

Let's proceed to step 2:
51 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 51

Moving on to step 3:
The number 51 fits into 439 8 times, leaving a remainder of 31.
The next digit of our result is 8. 
Result so far: 8.0
If we take 408 away from 439, we end up with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 51

Advancing to step 4:
51 goes into 314 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 306 from 314 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 51

Let's proceed to step 5:
51 can be fit into 82 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 861.0
If we subtract 51 from 82, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 51

On to step 6:
The number 51 fits into 311 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 8616.0
Subtract 306 from 311 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 51, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8616.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 8616.09
Subtract 459 from 500 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8616.098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8616.098
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
51 goes into 200 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 8616.09803
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.

On to step 12:
When dividing 470 by 51, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8616.098039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
110 divided by 51 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8616.0980392
Deduct 102 from 110 and we're left with 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 14:
The number 51 fits into 80 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 8616.09803921
Deduct 51 from 80 and we're left 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.

The final outcome is 8616.09803921, with a leftover of 2.9e-08.
