15141170 ÷ 131 
The aim is to understand the frequency of 131 in 15141170.

Let's proceed to step 1:
1 divided by 131 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 131

Step 2:
The number 131 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 131

Moving on to step 3:
When dividing 151 by 131, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 131 away from 151, we end up with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 131

Moving on to step 4:
204 divided by 131 is 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 131 from 204 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 131

Moving on to step 5:
131 can be fit into 731 5 times, resulting in a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtract 655 from 731 to get 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 131

On to step 6:
If we divide 761 by 131, we get 5 and a remainder of 106.
Put 5 as the next digit of the answer. 
Result so far: 1155.0
Deduct 655 from 761 and we're left with 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 131

On to step 7:
131 goes into 1067 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 11558.0
If we subtract 1048 from 1067, we get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 131

Going ahead to step 8:
190 divided by 131 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 115581.0
Deduct 131 from 190 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
131 goes into 590 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 115581.4
The remainder is 66 after subtracting 524 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
131 can be fit into 660 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 115581.45
Subtract 655 from 660 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 131 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 115581.45
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
131 goes into 500 3 times with a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 115581.4503
Subtracting 393 from 500 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 13:
When dividing 1070 by 131, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 115581.45038
Subtract 1048 from 1070 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
220 divided by 131 is 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 115581.450381
The remainder is 89 after subtracting 131 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 15:
When dividing 890 by 131, we get 6 with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 115581.4503816
If we take 786 away from 890, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
131 can be fit into 1040 7 times, resulting in a remainder of 123.
The next digit of our result is 7. 
Result so far: 115581.45038167
If we subtract 917 from 1040, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

After the division, we end up with 115581.45038167 and a remainder of 1.23e-07.
