We look at the division of 131412 by 86 
Our goal is to divide 131412 by 86.

Going ahead to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the 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 / 86

Going ahead to step 2:
If we divide 13 by 86, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 86

Advancing to step 3:
When dividing 131 by 86, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 45 after subtracting 86 from 131.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 86

Step 4:
When dividing 454 by 86, we get 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 430 from 454 leaves us with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 86

Let's proceed to step 5:
86 goes into 241 2 times with a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
The remainder is 69 after subtracting 172 from 241.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 86

On to step 6:
The number 86 fits into 692 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1528.0
If we subtract 688 from 692, 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.

Step 7:
When dividing 40 by 86, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1528.0
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.

Step 8:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 1528.04
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
The number 86 fits into 560 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 1528.046
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 86, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1528.0465
Subtract 430 from 440 to 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.

Let's proceed to step 11:
If we divide 100 by 86, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1528.04651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1528.046511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 1528.046511, and the remainder is 5.4e-06.
