We're dividing 878363 by 64 
We want to figure out the number of times 878363 can be divided by 64.

Let's proceed to step 1:
64 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 64

Let's proceed to step 2:
The number 64 fits into 87 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 87 and we're left with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 64

Moving on to step 3:
64 goes into 238 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 46 after subtracting 192 from 238.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 64

Step 4:
64 can be fit into 463 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 137.0
Subtracting 448 from 463 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 64

Moving on to step 5:
64 can be fit into 156 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1372.0
The remainder is 28 after subtracting 128 from 156.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 64

Moving on to step 6:
283 divided by 64 is 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 13724.0
If we take 256 away from 283, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
64 can be fit into 270 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 13724.4
The remainder is 14 after subtracting 256 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 64, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 13724.42
Subtracting 128 from 140 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
64 goes into 120 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 13724.421
If we subtract 64 from 120, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 13724.4218
If we subtract 512 from 560, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 13724.42187
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.

Let's proceed to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13724.421875
Subtract 320 from 320 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.

Advancing to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13724.421875
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.

Moving on to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13724.421875
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 13724.421875 and a remainder of 0.0.
