We divide 646963 by 8
We want to figure out the number of times 646963 can be divided by 8.

Moving on to step 1:
If we divide 6 by 8, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 8

Advancing to step 2:
When dividing 64 by 8, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 64 away from 64, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 8

Moving on to step 3:
If we divide 6 by 8, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 8

Step 4:
When dividing 69 by 8, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 808.0
The remainder is 5 after subtracting 64 from 69.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 8

Going ahead to step 5:
56 divided by 8 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 8087.0
Subtracting 56 from 56 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 8

Step 6:
3 divided by 8 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 80870.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
8 goes into 30 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 80870.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
8 goes into 60 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 80870.37
Deduct 56 from 60 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.

Going ahead to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 80870.375
If we subtract 40 from 40, 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.

Moving on to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80870.375
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.

Advancing to step 11:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80870.375
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.

The final outcome is 80870.375, with a leftover of 0.0.
