We look at the division of 865 by 49 
We want to divide 865 by 49.

Let's proceed to step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 49

Advancing to step 2:
The number 49 fits into 86 1 times, leaving a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 49 from 86 leaves us with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 49

Let's proceed to step 3:
375 divided by 49 is 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 343 from 375 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 4:
When dividing 320 by 49, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 17.6
If we take 294 away from 320, we end up 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.

Step 5:
260 divided by 49 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17.65
If we subtract 245 from 260, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
If we divide 150 by 49, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 17.653
Deduct 147 from 150 and we're left 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.

Moving on to step 7:
30 divided by 49 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 17.653
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 49, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 17.65306
Deduct 294 from 300 and we're left with 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 9:
60 divided by 49 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 17.653061
Deduct 49 from 60 and we're left 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.

Let's proceed to step 10:
The number 49 fits into 110 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 17.6530612
If we take 98 away from 110, 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.

On to step 11:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 17.65306122
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 17.65306122 with a remainder of 2.2e-08.
