We're dividing 865482 by 51 
We're looking to find how many times 51 goes into 865482.

Step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 51

Going ahead to step 2:
If we divide 86 by 51, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 51

Advancing to step 3:
51 goes into 355 6 times with a remainder of 49.
The next digit of our result is 6. 
Result so far: 16.0
If we take 306 away from 355, we end up with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 51

On to step 4:
51 goes into 494 9 times with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
If we take 459 away from 494, we end up with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 51

Let's proceed to step 5:
The number 51 fits into 358 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1697.0
If we subtract 357 from 358, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 51

Going ahead to step 6:
51 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 16970.0
If we take 0 away from 12, we end up 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.

Let's proceed to step 7:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 16970.2
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.

Let's proceed to step 8:
If we divide 180 by 51, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 16970.23
If we take 153 away from 180, we end up 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.

Advancing to step 9:
270 divided by 51 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 16970.235
The remainder is 15 after subtracting 255 from 270.
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:
51 goes into 150 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 16970.2352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 51 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 16970.23529
Subtracting 459 from 480 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
The number 51 fits into 210 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 16970.235294
The remainder is 6 after subtracting 204 from 210.
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:
60 divided by 51 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 16970.2352941
Deduct 51 from 60 and we're left 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.

Moving on to step 14:
If we divide 90 by 51, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 16970.23529411
If we take 51 away from 90, 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.

The final outcome is 16970.23529411, with a leftover of 3.9e-08.
