We're dividing 131389 by 42 
Our goal is to divide 131389 by 42.

Let's proceed to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Step 2:
42 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 42

Advancing to step 3:
When dividing 131 by 42, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 126 from 131, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 42

Going ahead to step 4:
When dividing 53 by 42, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 42 away from 53, we end up with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 42

Step 5:
If we divide 118 by 42, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 312.0
The remainder is 34 after subtracting 84 from 118.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 42

Step 6:
If we divide 349 by 42, we get 8 and a remainder of 13.
The next digit of our result is 8. 
Result so far: 3128.0
If we subtract 336 from 349, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 42 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3128.3
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3128.3
Subtracting 0 from 40 leaves us with 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 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 3128.309
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.

On to step 10:
220 divided by 42 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3128.3095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3128.30952
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.

Going ahead to step 12:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3128.309523
If we subtract 126 from 160, we get 34.
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 13:
42 goes into 340 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 3128.3095238
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.

Going ahead to step 14:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3128.3095238
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.

In conclusion, the division gives 3128.3095238 with a balance of 4e-08.
