870957 ÷ 79 
Let's see how many times 79 fits into 870957.

Moving on to step 1:
If we divide 8 by 79, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 79

Advancing to step 2:
79 can be fit into 87 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 79 from 87 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 79

Step 3:
80 divided by 79 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 79 away from 80, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 79

Going ahead to step 4:
When dividing 19 by 79, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 19 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 79

Going ahead to step 5:
If we divide 195 by 79, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 1102.0
The remainder is 37 after subtracting 158 from 195.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 79

On to step 6:
If we divide 377 by 79, we get 4 and a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 11024.0
Subtract 316 from 377 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 7:
If we divide 610 by 79, we get 7 and a remainder of 57.
The next digit of our result is 7. 
Result so far: 11024.7
Subtract 553 from 610 to 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.

Moving on to step 8:
79 goes into 570 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 11024.77
Subtract 553 from 570 to get 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 11024.77 with a remaining 0.017.
