131790 divided by 42 
We want to figure out the number of times 131790 can be divided by 42.

Moving on to step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 42

On to step 2:
When dividing 13 by 42, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 42

Moving on to step 3:
42 goes into 131 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 5 after subtracting 126 from 131.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 42

Going ahead to step 4:
42 goes into 57 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 15 after subtracting 42 from 57.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 42

Going ahead to step 5:
42 goes into 159 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
Deduct 126 from 159 and we're left with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 42

Going ahead to step 6:
42 can be fit into 330 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 3137.0
Subtract 294 from 330 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 42, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3137.8
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 3137.85
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3137.857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3137.8571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3137.85714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 3137.857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 3137.8571428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3137.85714285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 3137.85714285, and the remainder is 3e-08.
