We look at the division of 748646 by 64 
Let's see how many times 64 fits into 748646.

Going ahead to step 1:
When dividing 7 by 64, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 64

Step 2:
64 can be fit into 74 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 74 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 64

On to step 3:
64 can be fit into 108 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 64 from 108 leaves us with 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 64

Step 4:
The number 64 fits into 446 6 times, leaving a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 384 from 446 and we're left with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 64

Going ahead to step 5:
64 can be fit into 624 9 times, resulting in a remainder of 48.
The next digit of our result is 9. 
Result so far: 1169.0
Deduct 576 from 624 and we're left with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 64

On to step 6:
486 divided by 64 is 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 11697.0
If we subtract 448 from 486, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
64 can be fit into 380 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 11697.5
If we take 320 away from 380, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
The number 64 fits into 600 9 times, leaving a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 11697.59
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
64 can be fit into 240 3 times, resulting in a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 11697.593
Deduct 192 from 240 and we're left 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.

Step 10:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 11697.5937
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11697.59375
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.

Going ahead to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11697.59375
If we take 0 away from 0, 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.

Step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11697.59375
If we take 0 away from 0, 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.

The final result is 11697.59375 with a remainder of 0.0.
