We're dividing 808191 by 64 
We want to figure out the number of times 808191 can be divided by 64.

Advancing to step 1:
8 divided by 64 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 64

Advancing to step 2:
64 goes into 80 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 64 away from 80, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 64

Going ahead to step 3:
64 goes into 168 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 128 from 168 to get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 64

Step 4:
64 can be fit into 401 6 times, resulting in a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 384 from 401 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 64

Going ahead to step 5:
When dividing 179 by 64, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 1262.0
The remainder is 51 after subtracting 128 from 179.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 64

On to step 6:
If we divide 511 by 64, we get 7 and a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 12627.0
If we take 448 away from 511, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
64 goes into 630 9 times with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 12627.9
The remainder is 54 after subtracting 576 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
64 can be fit into 540 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 12627.98
Subtracting 512 from 540 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 64, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 12627.984
The remainder is 24 after subtracting 256 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
The number 64 fits into 240 3 times, leaving a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 12627.9843
Deduct 192 from 240 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.

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: 12627.98437
If we subtract 448 from 480, 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.

On to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12627.984375
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.

Let's proceed to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12627.984375
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.

Let's proceed to step 14:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12627.984375
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.

The final result is 12627.984375 with a remainder of 0.0.
