781392 divided by 64 
We want to figure out the number of times 781392 can be divided by 64.

Going ahead to step 1:
The number 64 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 64

On to step 2:
If we divide 78 by 64, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 64 from 78 and we're left with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 64

Advancing to step 3:
64 can be fit into 141 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 128 from 141 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 64

Moving on to step 4:
When dividing 133 by 64, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtracting 128 from 133 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 64

Moving on to step 5:
If we divide 59 by 64, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 1220.0
If we subtract 0 from 59, we get 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 64

Advancing to step 6:
64 can be fit into 592 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 12209.0
If we take 576 away from 592, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12209.2
Deduct 128 from 160 and we're left 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.

Going ahead to step 8:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12209.25
Subtracting 320 from 320 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.

Step 9:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12209.25
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.

Advancing to step 10:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12209.25
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.

Our division results in 12209.25 with a remaining 0.0.
