64246684 divided by 8 
Let's see how many times 8 fits into 64246684.

Step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 8

Advancing to step 2:
8 goes into 64 8 times 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.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 8

Going ahead to step 3:
When dividing 2 by 8, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 8

Going ahead to step 4:
24 divided by 8 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 803.0
If we subtract 24 from 24, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 8

On to step 5:
If we divide 6 by 8, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 8030.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 8

Going ahead to step 6:
8 goes into 66 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 80308.0
Subtract 64 from 66 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 8

Let's proceed to step 7:
28 divided by 8 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 803083.0
The remainder is 4 after subtracting 24 from 28.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 8

Let's proceed to step 8:
When dividing 44 by 8, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 8030835.0
Subtracting 40 from 44 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 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8030835.5
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.

Moving on 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: 8030835.5
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.

Moving on to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8030835.5
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.

After the division, we end up with 8030835.5 and a remainder of 0.0.
