We look at the division of 858773 by 8 
Our goal is to divide 858773 by 8.

Moving on to step 1:
When dividing 8 by 8, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 8 from 8, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

Advancing to step 2:
If we divide 5 by 8, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 8

Advancing to step 3:
8 goes into 58 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 56 from 58 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 8

Step 4:
If we divide 27 by 8, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
If we take 24 away from 27, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 8

Going ahead to step 5:
8 can be fit into 37 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 10734.0
Deduct 32 from 37 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 8

Going ahead to step 6:
8 can be fit into 53 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 107346.0
Subtracting 48 from 53 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 8, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 107346.6
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 107346.62
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 107346.625
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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 107346.625
Subtracting 0 from 0 leaves us 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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 107346.625
If we subtract 0 from 0, we 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.

Our division results in 107346.625 with a remaining 0.0.
