721633 divided by 64 
Our goal is to divide 721633 by 64.

Step 1:
64 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 64

On to step 2:
64 can be fit into 72 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 64 from 72, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 64

Moving on to step 3:
When dividing 81 by 64, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 64 from 81, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 64

Step 4:
64 goes into 176 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we subtract 128 from 176, we get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 64

Advancing to step 5:
If we divide 483 by 64, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 1127.0
Deduct 448 from 483 and we're left with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 64

Step 6:
64 can be fit into 353 5 times, resulting in a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 11275.0
If we subtract 320 from 353, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
64 goes into 330 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 11275.5
The remainder is 10 after subtracting 320 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 64, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 11275.51
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.

On to step 9:
360 divided by 64 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 11275.515
Subtract 320 from 360 to get 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:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 11275.5156
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.

Let's proceed to step 11:
160 divided by 64 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 11275.51562
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.

Let's proceed to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11275.515625
Subtracting 320 from 320 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 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11275.515625
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.

Step 14:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11275.515625
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.

The final result is 11275.515625 with a remainder of 0.0.
