Let's divide 789804 by 64
We're looking to find how many times 64 goes into 789804.

Step 1:
64 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 64

On to step 2:
The number 64 fits into 78 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we take 64 away from 78, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 64

Advancing to step 3:
The number 64 fits into 149 2 times, leaving a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 21 after subtracting 128 from 149.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 64

Moving on to step 4:
218 divided by 64 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we subtract 192 from 218, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 64

Step 5:
64 can be fit into 260 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 1234.0
If we subtract 256 from 260, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 64

On to step 6:
If we divide 44 by 64, we get 0 and a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 12340.0
The remainder is 44 after subtracting 0 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
If we divide 440 by 64, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 12340.6
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 12340.68
If we take 512 away from 560, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
When dividing 480 by 64, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 12340.687
Deduct 448 from 480 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.

Going ahead to step 10:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12340.6875
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 11:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12340.6875
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 12:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12340.6875
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 12340.6875 with a remainder of 0.0.
