313168 ÷ 42 
We want to figure out the number of times 313168 can be divided by 42.

Advancing to step 1:
3 divided by 42 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.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 42

Going ahead to step 2:
31 divided by 42 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 42

On to step 3:
When dividing 313 by 42, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 294 from 313, we get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 42

Going ahead to step 4:
42 can be fit into 191 4 times, resulting in a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 168 from 191 to get 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 42

Going ahead to step 5:
42 goes into 236 5 times with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 745.0
Deduct 210 from 236 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 42

Moving on to step 6:
42 can be fit into 268 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7456.0
If we take 252 away from 268, 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.

Advancing to step 7:
160 divided by 42 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 7456.3
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 7456.38
If we take 336 away from 340, we end up 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.

Going ahead to step 9:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7456.38
The remainder is 40 after subtracting 0 from 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 10:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 7456.3809
If we take 378 away from 400, 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.

Step 11:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7456.38095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 42, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 7456.380952
Subtracting 84 from 100 leaves us 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 13:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 7456.3809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 7456.38095238
If we subtract 336 from 340, 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.

Our division results in 7456.38095238 with a remaining 4e-09.
