We look at the division of 315258 by 64 
Let's see how many times 64 fits into 315258.

Going ahead to step 1:
3 divided by 64 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 64

Let's proceed to step 2:
When dividing 31 by 64, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 64

Step 3:
64 goes into 315 4 times with a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 256 from 315, we get 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 64

On to step 4:
If we divide 592 by 64, we get 9 and a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Deduct 576 from 592 and we're left with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 64

Moving on to step 5:
64 can be fit into 165 2 times, resulting in a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 492.0
Subtracting 128 from 165 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 64

On to step 6:
If we divide 378 by 64, we get 5 and a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 4925.0
The remainder is 58 after subtracting 320 from 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
580 divided by 64 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 4925.9
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 64 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 4925.9
Subtract 0 from 40 to 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.

On to step 9:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 4925.906
If we take 384 away from 400, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 64 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4925.9062
Deduct 128 from 160 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.

Step 11:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4925.90625
Subtracting 320 from 320 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.

Step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4925.90625
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.

On to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4925.90625
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 final outcome is 4925.90625, with a leftover of 0.0.
