1785861 ÷ 131 
The aim is to understand the frequency of 131 in 1785861.

Step 1:
1 divided by 131 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 131

Step 2:
The number 131 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 131

Step 3:
When dividing 178 by 131, we get 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 47 after subtracting 131 from 178.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 131

On to step 4:
If we divide 475 by 131, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 82 after subtracting 393 from 475.
Grab the next digit (8) from the dividend, add it to 82, then carry on: 828 / 131

Let's proceed to step 5:
131 goes into 828 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 786 from 828 to get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 131

Moving on to step 6:
131 can be fit into 426 3 times, resulting in a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 1363.0
Subtract 393 from 426 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 131

Going ahead to step 7:
331 divided by 131 is 2 with a remainder of 69.
The next digit of our result is 2. 
Result so far: 13632.0
The remainder is 69 after subtracting 262 from 331.
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 8:
131 can be fit into 690 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 13632.5
If we subtract 655 from 690, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
When dividing 350 by 131, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 13632.52
Subtracting 262 from 350 leaves us 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 10:
131 can be fit into 880 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 13632.526
Subtracting 786 from 880 leaves us 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.

Moving on to step 11:
940 divided by 131 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 13632.5267
Deduct 917 from 940 and we're left 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.

On to step 12:
131 can be fit into 230 1 times, resulting in a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 13632.52671
Deduct 131 from 230 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 13:
When dividing 990 by 131, we get 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 13632.526717
Deduct 917 from 990 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
730 divided by 131 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 13632.5267175
Deduct 655 from 730 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 15:
When dividing 750 by 131, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 13632.52671755
Subtract 655 from 750 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 13632.52671755, with a leftover of 9.5e-08.
