We divide 390511 by 64
We want to divide 390511 by 64.

Step 1:
3 divided by 64 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 64

Going ahead to step 2:
If we divide 39 by 64, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 64

On to step 3:
The number 64 fits into 390 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 384 away from 390, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 64

Let's proceed to step 4:
When dividing 65 by 64, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 64 from 65 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 64

On to step 5:
64 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 610.0
If we take 0 away from 11, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 64

Step 6:
111 divided by 64 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 6101.0
Subtract 64 from 111 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
470 divided by 64 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 6101.7
If we take 448 away from 470, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
When dividing 220 by 64, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 6101.73
Subtract 192 from 220 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 64, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 6101.734
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
64 goes into 240 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 6101.7343
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 6101.73437
Subtract 448 from 480 to get 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 12:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6101.734375
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.

Advancing to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6101.734375
Subtracting 0 from 0 leaves us 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:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 6101.734375
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 6101.734375 with a remainder of 0.0.
