We look at the division of 811387 by 64 
We want to figure out the number of times 811387 can be divided by 64.

On to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 64

Going ahead to step 2:
When dividing 81 by 64, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 64 from 81, we get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 64

Advancing to step 3:
171 divided by 64 is 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 128 from 171 leaves us with 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 64

Step 4:
433 divided by 64 is 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 384 away from 433, we end up with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 64

Step 5:
498 divided by 64 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
If we subtract 448 from 498, we get 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 64

Moving on to step 6:
When dividing 507 by 64, we get 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 12677.0
Subtract 448 from 507 to 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:
64 goes into 590 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 12677.9
Subtracting 576 from 590 leaves us 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.

On to step 8:
When dividing 140 by 64, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12677.92
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 64, we get 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 12677.921
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.

Going ahead to step 10:
If we divide 560 by 64, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 12677.9218
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 64 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 12677.92187
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12677.921875
If we take 320 away from 320, 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.

Moving on to step 13:
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: 12677.921875
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.

Moving on to step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12677.921875
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.

After the division, we end up with 12677.921875 and a remainder of 0.0.
