We look at the division of 155507 by 42 
Let's see how many times 42 fits into 155507.

Moving on to step 1:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 42

Let's proceed to step 2:
42 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 42

Advancing to step 3:
When dividing 155 by 42, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 126 from 155 to get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 42

Moving on to step 4:
42 can be fit into 295 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 294 from 295 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 42

Advancing to step 5:
10 divided by 42 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 370.0
If we take 0 away from 10, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 42

Advancing to step 6:
If we divide 107 by 42, we get 2 and a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 3702.0
If we subtract 84 from 107, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 42, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3702.5
Subtract 210 from 230 to get 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 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 3702.54
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
42 goes into 320 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 3702.547
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3702.5476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3702.54761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3702.547619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3702.547619
Deduct 0 from 20 and we're left 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.

On to step 14:
When dividing 200 by 42, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 3702.54761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 3702.54761904 with a remainder of 3.2e-08.
