859885 divided by 64 
Let's see how many times 64 fits into 859885.

Going ahead to step 1:
When dividing 8 by 64, we get 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.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 64

Going ahead to step 2:
If we divide 85 by 64, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 64 from 85 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 64

Moving on to step 3:
The number 64 fits into 219 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 192 from 219 leaves us with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 64

On to step 4:
The number 64 fits into 278 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
Subtract 256 from 278 to get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 64

On to step 5:
64 can be fit into 228 3 times, resulting in a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 1343.0
Deduct 192 from 228 and we're left with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 64

Moving on to step 6:
The number 64 fits into 365 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 13435.0
If we take 320 away from 365, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
If we divide 450 by 64, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 13435.7
If we subtract 448 from 450, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
64 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13435.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
64 can be fit into 200 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 13435.703
Deduct 192 from 200 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.

Advancing to step 10:
If we divide 80 by 64, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 13435.7031
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.

Let's proceed to step 11:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 13435.70312
If we subtract 128 from 160, 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.

Moving on to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13435.703125
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.

Moving on to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 13435.703125
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.

Let's proceed to step 14:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13435.703125
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.

The final result is 13435.703125 with a remainder of 0.0.
