We're dividing 131258 by 12 
Our goal is to divide 131258 by 12.

Moving on to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 12

Advancing to step 2:
When dividing 13 by 12, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 12 from 13, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 12

Moving on to step 3:
The number 12 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 12

Going ahead to step 4:
12 goes into 112 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 108 from 112 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 12

Going ahead to step 5:
The number 12 fits into 45 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 1093.0
Deduct 36 from 45 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Step 6:
If we divide 98 by 12, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 10938.0
Deduct 96 from 98 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 12 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10938.1
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10938.16
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10938.166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 10938.166, and the remainder is 0.0008.
