42715312 ÷ 168 
Let's see how many times 168 fits into 42715312.

Advancing to step 1:
The number 168 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 168

Moving on to step 2:
168 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 168

Moving on to step 3:
168 goes into 427 2 times with a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 336 from 427 and we're left with 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 168

Let's proceed to step 4:
168 can be fit into 911 5 times, resulting in a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 840 from 911 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 168

Advancing to step 5:
If we divide 715 by 168, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 254.0
The remainder is 43 after subtracting 672 from 715.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 168

On to step 6:
When dividing 433 by 168, we get 2 with a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 2542.0
If we subtract 336 from 433, we get 97.
Take the next digit (1) from the dividend and append it to 97, then repeat: 971 / 168

Going ahead to step 7:
The number 168 fits into 971 5 times, leaving a remainder of 131.
Write down 5 as next digit of the result. 
Result so far: 25425.0
If we subtract 840 from 971, we get 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 168

Let's proceed to step 8:
168 goes into 1312 7 times with a remainder of 136.
The next digit of our result is 7. 
Result so far: 254257.0
If we subtract 1176 from 1312, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 9:
If we divide 1360 by 168, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 254257.8
Deduct 1344 from 1360 and we're left 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.

On to step 10:
When dividing 160 by 168, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 254257.8
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
When dividing 1600 by 168, we get 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 254257.809
Subtract 1512 from 1600 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
168 goes into 880 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 254257.8095
If we take 840 away from 880, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
168 can be fit into 400 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 254257.80952
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
When dividing 640 by 168, we get 3 with a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 254257.809523
The remainder is 136 after subtracting 504 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
168 goes into 1360 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 254257.8095238
If we subtract 1344 from 1360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 16:
When dividing 160 by 168, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 254257.8095238
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 254257.8095238 with a remainder of 1.6e-07.
