817910 ÷ 64 
We want to figure out the number of times 817910 can be divided by 64.

Moving on 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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 64

On to step 2:
If we divide 81 by 64, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 64 from 81 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 64

Step 3:
When dividing 177 by 64, we get 2 with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 128 away from 177, we end up with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 64

On to step 4:
499 divided by 64 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 448 from 499 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 64

Advancing to step 5:
64 can be fit into 511 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 1277.0
Deduct 448 from 511 and we're left with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 64

Advancing to step 6:
When dividing 630 by 64, we get 9 with a remainder of 54.
The next digit of our result is 9. 
Result so far: 12779.0
Subtracting 576 from 630 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
540 divided by 64 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 12779.8
The remainder is 28 after subtracting 512 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
280 divided by 64 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 12779.84
If we take 256 away from 280, we end up with 24.
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 9:
The number 64 fits into 240 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 12779.843
If we subtract 192 from 240, we get 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 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 12779.8437
If we take 448 away from 480, we end up 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 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12779.84375
Deduct 320 from 320 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.

Going ahead to step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12779.84375
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.

Moving on to step 13:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12779.84375
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.

Our division results in 12779.84375 with a remaining 0.0.
