We look at the division of 621563 by 64 
Our goal is to divide 621563 by 64.

Going ahead to step 1:
The number 64 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 64

Advancing to step 2:
The number 64 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 64

Step 3:
When dividing 621 by 64, we get 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 576 from 621 and we're left with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 64

Step 4:
455 divided by 64 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 448 from 455 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 64

Step 5:
When dividing 76 by 64, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 971.0
The remainder is 12 after subtracting 64 from 76.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 64

Moving on to step 6:
If we divide 123 by 64, we get 1 and a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 9711.0
If we subtract 64 from 123, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
The number 64 fits into 590 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9711.9
If we take 576 away from 590, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 64 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 9711.92
Deduct 128 from 140 and we're left 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.

Advancing to step 9:
The number 64 fits into 120 1 times, leaving a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 9711.921
Subtracting 64 from 120 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 9711.9218
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.

Let's proceed to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 9711.92187
Deduct 448 from 480 and we're left 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:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9711.921875
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.

Advancing to step 13:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9711.921875
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.

Step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9711.921875
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.

The final result is 9711.921875 with a remainder of 0.0.
