We look at the division of 127780 by 42 
Our goal is to divide 127780 by 42.

Let's proceed to step 1:
42 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 42

Step 2:
42 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 42

Let's proceed to step 3:
127 divided by 42 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 126 from 127, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 42

Advancing to step 4:
42 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 42

On to step 5:
42 can be fit into 178 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 304.0
The remainder is 10 after subtracting 168 from 178.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 42

Advancing to step 6:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3042.0
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
42 goes into 160 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3042.3
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3042.38
If we take 336 away from 340, we end up 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.

Going ahead to step 9:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3042.38
Subtract 0 from 40 to 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.

Going ahead to step 10:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 3042.3809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3042.38095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3042.380952
If we subtract 84 from 100, 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.

Let's proceed to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3042.3809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3042.38095238
Deduct 336 from 340 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.

The final outcome is 3042.38095238, with a leftover of 4e-09.
