We look at the division of 42603154 by 492 
Our goal is to divide 42603154 by 492.

Going ahead to step 1:
If we divide 4 by 492, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 492

On to step 2:
When dividing 42 by 492, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 492

Let's proceed to step 3:
492 can be fit into 426 0 times, resulting in a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 426, we end up with 426.
Fetch the next digit (0) from the dividend, attach it to 426 and continue: 4260 / 492

Step 4:
When dividing 4260 by 492, we get 8 with a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 3936 away from 4260, we end up with 324.
Bring next digit (3) of the dividend behind the 324 and repeat the process: 3243 / 492

Moving on to step 5:
492 goes into 3243 6 times with a remainder of 291.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 2952 from 3243 leaves us with 291.
Bring next digit (1) of the dividend behind the 291 and repeat the process: 2911 / 492

Going ahead to step 6:
If we divide 2911 by 492, we get 5 and a remainder of 451.
Put 5 as the next digit of the answer. 
Result so far: 865.0
Subtracting 2460 from 2911 leaves us with 451.
Bring next digit (5) of the dividend behind the 451 and repeat the process: 4515 / 492

Going ahead to step 7:
The number 492 fits into 4515 9 times, leaving a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 8659.0
Subtracting 4428 from 4515 leaves us with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 492

On to step 8:
The number 492 fits into 874 1 times, leaving a remainder of 382.
The next digit of our result is 1. 
Result so far: 86591.0
Subtracting 492 from 874 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
If we divide 3820 by 492, we get 7 and a remainder of 376.
The number 7 becomes the next digit in our result. 
Result so far: 86591.7
The remainder is 376 after subtracting 3444 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
492 can be fit into 3760 7 times, resulting in a remainder of 316.
Record the quotient 7 as the next digit in the result. 
Result so far: 86591.77
Deduct 3444 from 3760 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Our division results in 86591.77 with a remaining 0.316.
