Let's divide 850209 by 64
We want to divide 850209 by 64.

Step 1:
If we divide 8 by 64, we get 0 and 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.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 64

Moving on to step 2:
If we divide 85 by 64, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 21 after subtracting 64 from 85.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 64

Going ahead to step 3:
210 divided by 64 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 192 from 210 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 64

On to step 4:
When dividing 182 by 64, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we subtract 128 from 182, we get 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 64

On to step 5:
64 goes into 540 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 1328.0
Subtract 512 from 540 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 64

Step 6:
The number 64 fits into 289 4 times, leaving a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 13284.0
The remainder is 33 after subtracting 256 from 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
If we divide 330 by 64, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 13284.5
If we subtract 320 from 330, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
64 goes into 100 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 13284.51
The remainder is 36 after subtracting 64 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
64 goes into 360 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 13284.515
If we subtract 320 from 360, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
64 can be fit into 400 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 13284.5156
The remainder is 16 after subtracting 384 from 400.
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.
Write down 2 as next digit of the result. 
Result so far: 13284.51562
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13284.515625
Subtract 320 from 320 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.

Going ahead to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13284.515625
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.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13284.515625
If we take 0 away from 0, we end up 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.

The final result is 13284.515625 with a remainder of 0.0.
