We're dividing 721669 by 64 
We want to divide 721669 by 64.

Going ahead to step 1:
The number 64 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 64

Step 2:
64 can be fit into 72 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 64 from 72 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 64

Going ahead to step 3:
The number 64 fits into 81 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 64 from 81 leaves us with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 64

Going ahead to step 4:
64 can be fit into 176 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 128 from 176, we get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 64

Moving on to step 5:
The number 64 fits into 486 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1127.0
The remainder is 38 after subtracting 448 from 486.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 64

Moving on to step 6:
64 can be fit into 389 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 11276.0
If we subtract 384 from 389, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
64 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11276.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 64, we get 7 and a remainder of 52.
The next digit of our result is 7. 
Result so far: 11276.07
If we subtract 448 from 500, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
The number 64 fits into 520 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 11276.078
Subtract 512 from 520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
64 goes into 80 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 11276.0781
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.

Step 11:
64 goes into 160 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 11276.07812
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.

Going ahead to 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: 11276.078125
Subtract 320 from 320 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.

Moving on to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11276.078125
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.

Going ahead to 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: 11276.078125
The remainder is 0 after subtracting 0 from 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 11276.078125 and a remainder of 0.0.
