We divide 215526 by 79
We want to figure out the number of times 215526 can be divided by 79.

On to step 1:
79 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 79

Step 2:
79 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 79

Let's proceed to step 3:
215 divided by 79 is 2 with a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 158 from 215 to get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 79

Step 4:
79 goes into 575 7 times with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 22 after subtracting 553 from 575.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 79

Let's proceed to step 5:
79 goes into 222 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 272.0
Deduct 158 from 222 and we're left with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 79

Let's proceed to step 6:
79 can be fit into 646 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2728.0
Subtract 632 from 646 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.

Advancing to step 7:
79 can be fit into 140 1 times, resulting in a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 2728.1
If we subtract 79 from 140, we 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.

Going ahead to step 8:
610 divided by 79 is 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 2728.17
The remainder is 57 after subtracting 553 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
570 divided by 79 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2728.177
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 2728.177 with a remainder of 0.0017.
