We're dividing 843674 by 8 
We're looking to find how many times 8 goes into 843674.

Going ahead to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 8

Step 2:
8 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 8

Moving on to step 3:
8 can be fit into 43 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 105.0
Deduct 40 from 43 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 8

Step 4:
The number 8 fits into 36 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1054.0
Subtract 32 from 36 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 8

Moving on to step 5:
The number 8 fits into 47 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 10545.0
The remainder is 7 after subtracting 40 from 47.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 8

Advancing to step 6:
8 goes into 74 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 105459.0
The remainder is 2 after subtracting 72 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 105459.2
If we take 16 away from 20, we end up 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.

On to step 8:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 105459.25
Subtracting 40 from 40 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.

Moving on to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 105459.25
If we take 0 away from 0, 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.

Step 10:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 105459.25
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.

Our division results in 105459.25 with a remaining 0.0.
