42070157 ÷ 168 
Our goal is to divide 42070157 by 168.

On to step 1:
168 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 168

Let's proceed to step 2:
If we divide 42 by 168, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 168

Moving on to step 3:
When dividing 420 by 168, we get 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 336 from 420 to get 84.
Take the next digit (7) from the dividend and append it to 84, then repeat: 847 / 168

Advancing to step 4:
The number 168 fits into 847 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 840 from 847, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 168

On to step 5:
70 divided by 168 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtract 0 from 70 to get 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 168

On to step 6:
701 divided by 168 is 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 2504.0
If we take 672 away from 701, we end up with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 168

Step 7:
The number 168 fits into 295 1 times, leaving a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 25041.0
If we take 168 away from 295, we end up with 127.
Include the next digit (7) from the dividend after 127, then repeat: 1277 / 168

Moving on to step 8:
The number 168 fits into 1277 7 times, leaving a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 250417.0
The remainder is 101 after subtracting 1176 from 1277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
When dividing 1010 by 168, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 250417.6
Subtracting 1008 from 1010 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 168 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 250417.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 168, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 250417.601
Subtracting 168 from 200 leaves us 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 12:
168 can be fit into 320 1 times, resulting in a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 250417.6011
If we take 168 away from 320, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 250417.6011 with a remainder of 0.00152.
