We look at the division of 42126432 by 154 
Let's see how many times 154 fits into 42126432.

Advancing to step 1:
154 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in 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 / 154

Moving on to step 2:
When dividing 42 by 154, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 154

Let's proceed to step 3:
If we divide 421 by 154, we get 2 and a remainder of 113.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 113 after subtracting 308 from 421.
Bring next digit (2) of the dividend behind the 113 and repeat the process: 1132 / 154

Moving on to step 4:
If we divide 1132 by 154, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 1078 from 1132, we get 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 154

Let's proceed to step 5:
546 divided by 154 is 3 with a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 273.0
Subtract 462 from 546 to get 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 154

Going ahead to step 6:
154 can be fit into 844 5 times, resulting in a remainder of 74.
The next digit of our result is 5. 
Result so far: 2735.0
Subtract 770 from 844 to get 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 154

Moving on to step 7:
When dividing 743 by 154, we get 4 with a remainder of 127.
Record the quotient 4 as the next digit in the result. 
Result so far: 27354.0
Subtracting 616 from 743 leaves us with 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 154

Step 8:
154 can be fit into 1272 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 273548.0
If we subtract 1232 from 1272, we 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.

On to step 9:
154 can be fit into 400 2 times, resulting in a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 273548.2
Subtracting 308 from 400 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 10:
The number 154 fits into 920 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 273548.25
Subtracting 770 from 920 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
154 goes into 1500 9 times with a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 273548.259
If we take 1386 away from 1500, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 12:
154 goes into 1140 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 273548.2597
Deduct 1078 from 1140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
When dividing 620 by 154, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 273548.25974
Deduct 616 from 620 and we're left 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.

Step 14:
40 divided by 154 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 273548.25974
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.

Moving on to step 15:
154 can be fit into 400 2 times, resulting in a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 273548.2597402
Deduct 308 from 400 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 16:
154 can be fit into 920 5 times, resulting in a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 273548.25974025
If we subtract 770 from 920, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 273548.25974025 with a balance of 1.5e-07.
