Let's divide 646674 by 8
We want to divide 646674 by 8.

On to step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 8

Advancing to step 2:
The number 8 fits into 64 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 64 from 64 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 8

Step 3:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 8

Advancing to step 4:
When dividing 66 by 8, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 808.0
If we subtract 64 from 66, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 8

Going ahead to step 5:
8 goes into 27 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 8083.0
Deduct 24 from 27 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 8

Going ahead to step 6:
When dividing 34 by 8, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 80834.0
The remainder is 2 after subtracting 32 from 34.
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:
20 divided by 8 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 80834.2
Deduct 16 from 20 and we're left 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:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 80834.25
Subtract 40 from 40 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.

Moving on to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80834.25
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:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 80834.25
The remainder is 0 after subtracting 0 from 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 80834.25 with a remainder of 0.0.
