64307747 divided by 857 
Our goal is to divide 64307747 by 857.

On to step 1:
If we divide 6 by 857, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 857

On to step 2:
857 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 857

Moving on to step 3:
857 goes into 643 0 times with a remainder of 643.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 643, we get 643.
Include the next digit (0) from the dividend after 643, then repeat: 6430 / 857

On to step 4:
857 goes into 6430 7 times with a remainder of 431.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5999 from 6430 leaves us with 431.
Bring next digit (7) of the dividend behind the 431 and repeat the process: 4317 / 857

Moving on to step 5:
857 goes into 4317 5 times with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 4285 from 4317 leaves us with 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 857

Going ahead to step 6:
857 can be fit into 327 0 times, resulting in a remainder of 327.
The next digit of our result is 0. 
Result so far: 750.0
If we subtract 0 from 327, we get 327.
Grab the next digit (4) from the dividend, add it to 327, then carry on: 3274 / 857

Advancing to step 7:
The number 857 fits into 3274 3 times, leaving a remainder of 703.
Record the quotient 3 as the next digit in the result. 
Result so far: 7503.0
Subtract 2571 from 3274 to get 703.
Grab the next digit (7) from the dividend, add it to 703, then carry on: 7037 / 857

Let's proceed to step 8:
When dividing 7037 by 857, we get 8 with a remainder of 181.
Write down 8 as next digit of the result. 
Result so far: 75038.0
Subtract 6856 from 7037 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
If we divide 1810 by 857, we get 2 and a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 75038.2
If we take 1714 away from 1810, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 10:
960 divided by 857 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 75038.21
Subtract 857 from 960 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 11:
857 can be fit into 1030 1 times, resulting in a remainder of 173.
Record the quotient 1 as the next digit in the result. 
Result so far: 75038.211
If we subtract 857 from 1030, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 75038.211 with a remainder of 0.0173.
