857709 divided by 64 
We want to figure out the number of times 857709 can be divided by 64.

Let's proceed to step 1:
64 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 64

Moving on to step 2:
When dividing 85 by 64, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 21 after subtracting 64 from 85.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 64

Going ahead to step 3:
64 can be fit into 217 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 192 from 217 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 64

Advancing to step 4:
64 goes into 257 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we take 256 away from 257, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 64

Moving on to step 5:
10 divided by 64 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1340.0
If we subtract 0 from 10, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 64

On to step 6:
64 goes into 109 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 13401.0
If we subtract 64 from 109, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
If we divide 450 by 64, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 13401.7
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.

Let's proceed to step 8:
The number 64 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13401.7
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 64 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 13401.703
Subtracting 192 from 200 leaves us 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.

Moving on to step 10:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 13401.7031
Deduct 64 from 80 and we're left 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.

Advancing to step 11:
64 goes into 160 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 13401.70312
Subtract 128 from 160 to 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.

Going ahead to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13401.703125
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
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: 13401.703125
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.

Going ahead to step 14:
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: 13401.703125
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 13401.703125 with a remainder of 0.0.
