We're dividing 131499 by 42 
Let's see how many times 42 fits into 131499.

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
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 42

On to step 2:
13 divided by 42 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 42

Moving on to step 3:
42 can be fit into 131 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 126 away from 131, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 42

On to step 4:
42 goes into 54 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 42 from 54 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 42

Step 5:
The number 42 fits into 129 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtracting 126 from 129 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 42

Moving on to step 6:
39 divided by 42 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 3130.0
Subtract 0 from 39 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
When dividing 390 by 42, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 3130.9
If we take 378 away from 390, we end up 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 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 3130.92
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3130.928
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.

Advancing to step 10:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3130.9285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3130.92857
Deduct 294 from 300 and we're left with 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 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 3130.928571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 3130.9285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 3130.92857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 3130.92857142, with a leftover of 3.6e-08.
