855816 divided by 64 
We want to figure out the number of times 855816 can be divided by 64.

On to step 1:
64 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 64

Moving on to step 2:
64 goes into 85 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 64 from 85, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 64

Let's proceed to step 3:
64 can be fit into 215 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 192 from 215 and we're left with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 64

Step 4:
64 goes into 238 3 times with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Deduct 192 from 238 and we're left with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 64

Let's proceed to step 5:
If we divide 461 by 64, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 1337.0
If we subtract 448 from 461, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 64

Let's proceed to step 6:
When dividing 136 by 64, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 13372.0
Deduct 128 from 136 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 13372.1
Subtract 64 from 80 to 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.

Advancing to step 8:
The number 64 fits into 160 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 13372.12
Deduct 128 from 160 and we're left 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 9:
64 goes into 320 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13372.125
If we subtract 320 from 320, 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.

Going ahead to step 10:
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: 13372.125
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.

Going ahead to step 11:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13372.125
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 13372.125 and a remainder of 0.0.
