We look at the division of 15840540 by 131 
We're looking to find how many times 131 goes into 15840540.

On to step 1:
The number 131 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 131

Going ahead to step 2:
131 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 131

On to step 3:
131 can be fit into 158 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 131 from 158, we get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 131

On to step 4:
If we divide 274 by 131, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 262 from 274 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 131

Going ahead to step 5:
When dividing 120 by 131, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 120, we get 120.
Take the next digit (5) from the dividend and append it to 120, then repeat: 1205 / 131

On to step 6:
1205 divided by 131 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1209.0
Subtracting 1179 from 1205 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 131

Step 7:
If we divide 264 by 131, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12092.0
If we take 262 away from 264, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 131

Going ahead to step 8:
The number 131 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 120920.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
131 goes into 200 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 120920.1
If we take 131 away from 200, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
690 divided by 131 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 120920.15
The remainder is 35 after subtracting 655 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
131 can be fit into 350 2 times, resulting in a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 120920.152
If we take 262 away from 350, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
131 goes into 880 6 times with a remainder of 94.
Write down 6 as next digit of the result. 
Result so far: 120920.1526
Deduct 786 from 880 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 13:
131 goes into 940 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 120920.15267
If we take 917 away from 940, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
131 can be fit into 230 1 times, resulting in a remainder of 99.
The next digit of our result is 1. 
Result so far: 120920.152671
The remainder is 99 after subtracting 131 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 15:
990 divided by 131 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 120920.1526717
Subtract 917 from 990 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 16:
131 can be fit into 730 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 120920.15267175
The remainder is 75 after subtracting 655 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 120920.15267175, and the remainder is 7.5e-08.
