We divide 64743957 by 8
We want to figure out the number of times 64743957 can be divided by 8.

Let's proceed to step 1:
6 divided by 8 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 8

Going ahead 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
The remainder is 0 after subtracting 64 from 64.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 8

Step 3:
The number 8 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 8

Going ahead to step 4:
If we divide 74 by 8, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
Subtracting 72 from 74 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 8

Advancing to step 5:
If we divide 23 by 8, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 8092.0
The remainder is 7 after subtracting 16 from 23.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 8

On to step 6:
79 divided by 8 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 80929.0
The remainder is 7 after subtracting 72 from 79.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 8

Going ahead to step 7:
The number 8 fits into 75 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 809299.0
Subtract 72 from 75 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 8

Going ahead to step 8:
8 can be fit into 37 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 8092994.0
Deduct 32 from 37 and we're left 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.

Advancing to step 9:
If we divide 50 by 8, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 8092994.6
If we take 48 away from 50, we end up with 2.
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 10:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 8092994.62
Subtracting 16 from 20 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.

Moving on to step 11:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8092994.625
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.

On to step 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8092994.625
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.

Moving on to step 13:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8092994.625
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.

After the division, we end up with 8092994.625 and a remainder of 0.0.
