Let's divide 503980 by 64
We're looking to find how many times 64 goes into 503980.

Advancing to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 64

On to step 2:
If we divide 50 by 64, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 64

Let's proceed to step 3:
The number 64 fits into 503 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 448 from 503 and we're left with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 64

Moving on to step 4:
64 goes into 559 8 times with a remainder of 47.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 512 from 559 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 64

Advancing to step 5:
64 goes into 478 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 787.0
Deduct 448 from 478 and we're left with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 64

On to step 6:
300 divided by 64 is 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 7874.0
If we take 256 away from 300, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
If we divide 440 by 64, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 7874.6
Subtract 384 from 440 to 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.

Let's proceed to step 8:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 7874.68
Deduct 512 from 560 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.

Going ahead to step 9:
64 goes into 480 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7874.687
If we subtract 448 from 480, we 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.

Step 10:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7874.6875
If we subtract 320 from 320, 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.

Let's proceed to step 11:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7874.6875
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.

Going ahead to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7874.6875
Deduct 0 from 0 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.

After the division, we end up with 7874.6875 and a remainder of 0.0.
