Let's divide 315904 by 68
Let's see how many times 68 fits into 315904.

Advancing to step 1:
When dividing 3 by 68, we get 0 with a remainder of 3.
The next digit of our result is 0. 
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 / 68

On to step 2:
68 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 68

Step 3:
If we divide 315 by 68, we get 4 and a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 272 away from 315, we end up with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 68

Step 4:
When dividing 439 by 68, we get 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 408 from 439 leaves us with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 68

On to step 5:
68 can be fit into 310 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 464.0
If we subtract 272 from 310, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 68

On to step 6:
The number 68 fits into 384 5 times, leaving a remainder of 44.
The next digit of our result is 5. 
Result so far: 4645.0
If we subtract 340 from 384, we 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.

Advancing to step 7:
When dividing 440 by 68, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4645.6
Deduct 408 from 440 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.

Let's proceed to step 8:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4645.64
Subtract 272 from 320 to 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.

Going ahead to step 9:
68 goes into 480 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4645.647
If we subtract 476 from 480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 68 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4645.647
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.

Advancing to step 11:
When dividing 400 by 68, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4645.64705
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 4645.647058
Subtracting 544 from 600 leaves us 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 13:
68 can be fit into 560 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 4645.6470588
The remainder is 16 after subtracting 544 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 4645.6470588 with a remaining 1.6e-07.
