We're dividing 870202 by 8 
Our goal is to divide 870202 by 8.

Going ahead to step 1:
8 goes into 8 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 8

Advancing to step 2:
If we divide 7 by 8, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 8

On to step 3:
70 divided by 8 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 64 from 70 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 8

On to step 4:
62 divided by 8 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 1087.0
Subtracting 56 from 62 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 8

Step 5:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 10877.0
The remainder is 4 after subtracting 56 from 60.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

On to step 6:
If we divide 42 by 8, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 108775.0
If we take 40 away from 42, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 108775.2
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 108775.25
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 108775.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 108775.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 108775.25 with a remainder of 0.0.
