Let's divide 851508 by 51
Let's see how many times 51 fits into 851508.

Advancing to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 51

Going ahead to step 2:
If we divide 85 by 51, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 85, we get 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 51

On to step 3:
When dividing 341 by 51, we get 6 with a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 306 away from 341, we end up with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 51

Going ahead to step 4:
355 divided by 51 is 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Deduct 306 from 355 and we're left with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 51

Advancing to step 5:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 1669.0
Subtracting 459 from 490 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 51

Let's proceed to step 6:
If we divide 318 by 51, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 16696.0
Subtracting 306 from 318 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
51 goes into 120 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 16696.2
Subtracting 102 from 120 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 16696.23
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 16696.235
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 51, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 16696.2352
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
The number 51 fits into 480 9 times, leaving a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 16696.23529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
51 goes into 210 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 16696.235294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
When dividing 60 by 51, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 16696.2352941
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
51 goes into 90 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 16696.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 16696.23529411 and a remainder of 3.9e-08.
