We look at the division of 439649 by 51 
We want to figure out the number of times 439649 can be divided by 51.

Advancing 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 take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 51

Advancing to step 2:
51 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 51

On to step 3:
439 divided by 51 is 8 with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 408 from 439 to get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 51

Let's proceed to step 4:
When dividing 316 by 51, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 306 from 316 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 51

Moving on to step 5:
If we divide 104 by 51, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 862.0
If we take 102 away from 104, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 51

Moving on to step 6:
51 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 8620.0
Deduct 0 from 29 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.

Step 7:
51 goes into 290 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8620.5
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
When dividing 350 by 51, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 8620.56
If we take 306 away from 350, we end up 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.

Let's proceed to step 9:
51 goes into 440 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8620.568
Subtracting 408 from 440 leaves us 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.

Moving on to step 10:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 8620.5686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 8620.56862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 8620.568627
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
If we divide 230 by 51, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 8620.5686274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
51 goes into 260 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8620.56862745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 8620.56862745 with a balance of 5e-09.
