We look at the division of 503317 by 64 
We want to figure out the number of times 503317 can be divided by 64.

Step 1:
If we divide 5 by 64, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 64

Let's proceed to step 2:
64 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 64

On to step 3:
The number 64 fits into 503 7 times, leaving a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 448 away from 503, we end up with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 64

Advancing to step 4:
When dividing 553 by 64, we get 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 512 from 553 leaves us with 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 64

Let's proceed to step 5:
64 goes into 411 6 times with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 786.0
Subtracting 384 from 411 leaves us with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 64

Advancing to step 6:
64 can be fit into 277 4 times, resulting in a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 7864.0
Deduct 256 from 277 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
210 divided by 64 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 7864.3
If we take 192 away from 210, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 64 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 7864.32
If we take 128 away from 180, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
When dividing 520 by 64, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 7864.328
Subtracting 512 from 520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
80 divided by 64 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 7864.3281
Subtracting 64 from 80 leaves us 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.

Going ahead to step 11:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 7864.32812
Subtracting 128 from 160 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.

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: 7864.328125
Deduct 320 from 320 and we're left 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.

Moving on to step 13:
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: 7864.328125
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 14:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7864.328125
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 quotient of the division is 7864.328125, and the remainder is 0.0.
