We're dividing 839996 by 51 
We want to figure out the number of times 839996 can be divided by 51.

Step 1:
51 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 51

Advancing to step 2:
51 goes into 83 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 83, we get 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 51

Advancing to step 3:
329 divided by 51 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 306 from 329 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 51

Advancing to step 4:
239 divided by 51 is 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 164.0
If we subtract 204 from 239, we get 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 51

Advancing to step 5:
The number 51 fits into 359 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1647.0
Deduct 357 from 359 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 51

Step 6:
51 goes into 26 0 times with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 16470.0
Subtract 0 from 26 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 16470.5
If we take 255 away from 260, we end up 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.

Step 8:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 16470.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 16470.509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
If we divide 410 by 51, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 16470.5098
Deduct 408 from 410 and we're left with 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 11:
If we divide 20 by 51, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16470.5098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
200 divided by 51 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 16470.509803
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.

Moving on to step 13:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 16470.5098039
If we take 459 away from 470, we end up 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.

Going ahead to step 14:
51 goes into 110 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16470.50980392
Subtract 102 from 110 to 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.

Our division results in 16470.50980392 with a remaining 8e-09.
