We divide 783975 by 64
We want to divide 783975 by 64.

Advancing to step 1:
64 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 64

Advancing to step 2:
When dividing 78 by 64, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 64 away from 78, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 64

Advancing to step 3:
The number 64 fits into 143 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 128 from 143 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 64

Going ahead to step 4:
When dividing 159 by 64, we get 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 128 from 159 and we're left with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 64

On to step 5:
When dividing 317 by 64, we get 4 with a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 1224.0
Subtracting 256 from 317 leaves us with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 64

Let's proceed to step 6:
64 goes into 615 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 12249.0
Subtract 576 from 615 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
64 goes into 390 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 12249.6
Subtracting 384 from 390 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 64 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 12249.6
If we take 0 away from 60, 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 9:
If we divide 600 by 64, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 12249.609
Subtracting 576 from 600 leaves us 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 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 12249.6093
The remainder is 48 after subtracting 192 from 240.
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 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 12249.60937
If we take 448 away from 480, we end up 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.

Moving on to step 12:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12249.609375
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 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12249.609375
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.

Advancing to step 14:
64 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12249.609375
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.

After the division, we end up with 12249.609375 and a remainder of 0.0.
