393580 divided by 64 
We're looking to find how many times 64 goes into 393580.

Advancing to step 1:
When dividing 3 by 64, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 64

Advancing to step 2:
If we divide 39 by 64, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 64

Going ahead to step 3:
393 divided by 64 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 384 from 393 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 64

Step 4:
When dividing 95 by 64, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 64 from 95 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 64

Going ahead to step 5:
If we divide 318 by 64, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 614.0
Deduct 256 from 318 and we're left with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 64

Advancing to step 6:
The number 64 fits into 620 9 times, leaving a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 6149.0
The remainder is 44 after subtracting 576 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 6149.6
Deduct 384 from 440 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to 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: 6149.68
The remainder is 48 after subtracting 512 from 560.
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:
64 can be fit into 480 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 6149.687
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.

Advancing to step 10:
When dividing 320 by 64, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6149.6875
Deduct 320 from 320 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.

Moving on to step 11:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6149.6875
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.

Advancing to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6149.6875
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 quotient of the division is 6149.6875, and the remainder is 0.0.
