We're dividing 64645712 by 394 
Our goal is to divide 64645712 by 394.

Step 1:
When dividing 6 by 394, we get 0 with a remainder of 6.
The next digit of our result is 0. 
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 / 394

Let's proceed to step 2:
The number 394 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 394

Step 3:
If we divide 646 by 394, we get 1 and a remainder of 252.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 252 after subtracting 394 from 646.
Grab the next digit (4) from the dividend, add it to 252, then carry on: 2524 / 394

Step 4:
394 goes into 2524 6 times with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2364 from 2524 to get 160.
Bring next digit (5) of the dividend behind the 160 and repeat the process: 1605 / 394

Step 5:
1605 divided by 394 is 4 with a remainder of 29.
The next digit of our result is 4. 
Result so far: 164.0
Subtracting 1576 from 1605 leaves us with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 394

Advancing to step 6:
297 divided by 394 is 0 with a remainder of 297.
Record the quotient 0 as the next digit in the result. 
Result so far: 1640.0
The remainder is 297 after subtracting 0 from 297.
Take the next digit (1) from the dividend and append it to 297, then repeat: 2971 / 394

Advancing to step 7:
2971 divided by 394 is 7 with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 16407.0
If we subtract 2758 from 2971, we get 213.
Include the next digit (2) from the dividend after 213, then repeat: 2132 / 394

Advancing to step 8:
2132 divided by 394 is 5 with a remainder of 162.
Record the quotient 5 as the next digit in the result. 
Result so far: 164075.0
If we subtract 1970 from 2132, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
1620 divided by 394 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 164075.4
Subtract 1576 from 1620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
440 divided by 394 is 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 164075.41
If we take 394 away from 440, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
394 can be fit into 460 1 times, resulting in a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 164075.411
Subtract 394 from 460 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 164075.411 with a balance of 0.0066.
