823128 divided by 51 
We're looking to find how many times 51 goes into 823128.

Going ahead to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 51

Let's proceed to step 2:
If we divide 82 by 51, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 82 and we're left with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 51

Let's proceed to step 3:
The number 51 fits into 313 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 306 from 313 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 51

Let's proceed to step 4:
51 can be fit into 71 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we subtract 51 from 71, we get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 51

Advancing to step 5:
202 divided by 51 is 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 1613.0
If we subtract 153 from 202, we get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 51

On to step 6:
The number 51 fits into 498 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 16139.0
If we take 459 away from 498, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 51 fits into 390 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 16139.7
Deduct 357 from 390 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
330 divided by 51 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 16139.76
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 16139.764
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 51 fits into 360 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 16139.7647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
The number 51 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 16139.7647
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
51 goes into 300 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 16139.764705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
If we divide 450 by 51, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 16139.7647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
51 goes into 420 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 16139.76470588
Subtract 408 from 420 to 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.

After the division, we end up with 16139.76470588 and a remainder of 1.2e-08.
