We look at the division of 315606 by 64 
We want to figure out the number of times 315606 can be divided by 64.

Step 1:
When dividing 3 by 64, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 64

Step 2:
31 divided by 64 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 64

Going ahead to step 3:
When dividing 315 by 64, we get 4 with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 59 after subtracting 256 from 315.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 64

Step 4:
64 can be fit into 596 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 576 from 596, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 64

Step 5:
If we divide 200 by 64, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 493.0
If we subtract 192 from 200, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 64

Advancing to step 6:
When dividing 86 by 64, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 4931.0
Deduct 64 from 86 and we're left 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.

Advancing to step 7:
The number 64 fits into 220 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 4931.3
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.

On to step 8:
280 divided by 64 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4931.34
Deduct 256 from 280 and we're left 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.

Step 9:
240 divided by 64 is 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 4931.343
Deduct 192 from 240 and we're left 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.

Step 10:
480 divided by 64 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 4931.3437
If we subtract 448 from 480, we 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.

Moving on to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4931.34375
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 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4931.34375
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 13:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4931.34375
Subtract 0 from 0 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.

After the division, we end up with 4931.34375 and a remainder of 0.0.
