We're dividing 131170 by 42 
Our goal is to divide 131170 by 42.

Going ahead to step 1:
1 divided by 42 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 42

Advancing to step 2:
If we divide 13 by 42, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 42

Step 3:
42 goes into 131 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 5 after subtracting 126 from 131.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 42

Step 4:
42 can be fit into 51 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 42 from 51 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 42

Advancing to step 5:
The number 42 fits into 97 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 312.0
Subtract 84 from 97 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 42

Going ahead to step 6:
130 divided by 42 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3123.0
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.

Moving on to step 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3123.0
If we take 0 away from 40, we end up 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.

On to step 8:
If we divide 400 by 42, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 3123.09
Deduct 378 from 400 and we're left 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.

Going ahead to step 9:
If we divide 220 by 42, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3123.095
If we subtract 210 from 220, we 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.

On to step 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3123.0952
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.

Let's proceed to step 11:
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: 3123.09523
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.

Step 12:
340 divided by 42 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3123.095238
The remainder is 4 after subtracting 336 from 340.
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 13:
When dividing 40 by 42, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3123.095238
Deduct 0 from 40 and we're left 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.

Step 14:
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: 3123.09523809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 3123.09523809 with a remainder of 2.2e-08.
