We look at the division of 663585 by 64 
Our goal is to divide 663585 by 64.

Let's proceed to step 1:
When dividing 6 by 64, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 64

Advancing to step 2:
When dividing 66 by 64, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 64 from 66, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 64

Advancing to step 3:
If we divide 23 by 64, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 23, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 64

Advancing to step 4:
When dividing 235 by 64, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 103.0
The remainder is 43 after subtracting 192 from 235.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 64

Step 5:
64 goes into 438 6 times with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 1036.0
Subtract 384 from 438 to get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 64

Moving on to step 6:
545 divided by 64 is 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 10368.0
The remainder is 33 after subtracting 512 from 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
The number 64 fits into 330 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10368.5
Deduct 320 from 330 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 64 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 10368.51
The remainder is 36 after subtracting 64 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 64 fits into 360 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 10368.515
If we take 320 away from 360, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 64 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10368.5156
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 10368.51562
If we subtract 128 from 160, 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 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10368.515625
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.

Advancing to step 13:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10368.515625
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.

Advancing to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10368.515625
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 10368.515625, and the remainder is 0.0.
