Let's divide 865143 by 79
We want to divide 865143 by 79.

Step 1:
The number 79 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
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 / 79

Let's proceed to step 2:
79 goes into 86 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 79 from 86 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 79

Moving on to step 3:
75 divided by 79 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 75, we get 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 79

On to step 4:
When dividing 751 by 79, we get 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 711 from 751 to get 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 79

Going ahead to step 5:
The number 79 fits into 404 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
Deduct 395 from 404 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 79

Step 6:
79 can be fit into 93 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 10951.0
Subtract 79 from 93 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 79, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 10951.1
Subtract 79 from 140 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 8:
610 divided by 79 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 10951.17
If we subtract 553 from 610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
The number 79 fits into 570 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 10951.177
Subtracting 553 from 570 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 10951.177 with a remaining 0.0017.
