We're dividing 641238 by 64 
We want to figure out the number of times 641238 can be divided by 64.

Let's proceed to step 1:
When dividing 6 by 64, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 64

Moving on to step 2:
64 divided by 64 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 64 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 64

Step 3:
The number 64 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 64

Going ahead to step 4:
If we divide 12 by 64, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 12, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 64

Let's proceed to step 5:
When dividing 123 by 64, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1001.0
Deduct 64 from 123 and we're left with 59.
Fetch the next digit (8) from the dividend, attach it to 59 and continue: 598 / 64

Let's proceed to step 6:
64 goes into 598 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 10019.0
Subtract 576 from 598 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
220 divided by 64 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 10019.3
If we subtract 192 from 220, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 64, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10019.34
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 64 fits into 240 3 times, leaving a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 10019.343
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 64 fits into 480 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 10019.3437
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10019.34375
The remainder is 0 after subtracting 320 from 320.
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 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10019.34375
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.

On to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10019.34375
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.

The final result is 10019.34375 with a remainder of 0.0.
