We look at the division of 85800034 by 131 
The aim is to understand the frequency of 131 in 85800034.

Advancing to step 1:
If we divide 8 by 131, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 131

Going ahead to step 2:
85 divided by 131 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 131

Advancing to step 3:
When dividing 858 by 131, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 786 from 858 to get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 131

Moving on to step 4:
131 can be fit into 720 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 655 from 720 to get 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 131

Going ahead to step 5:
The number 131 fits into 650 4 times, leaving a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 654.0
If we take 524 away from 650, we end up with 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 131

Advancing to step 6:
If we divide 1260 by 131, we get 9 and a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 6549.0
Subtract 1179 from 1260 to get 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 131

Going ahead to step 7:
The number 131 fits into 813 6 times, leaving a remainder of 27.
The next digit of our result is 6. 
Result so far: 65496.0
The remainder is 27 after subtracting 786 from 813.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 131

On to step 8:
131 goes into 274 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 654962.0
Subtracting 262 from 274 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
131 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 654962.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
If we divide 1200 by 131, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 654962.09
Deduct 1179 from 1200 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
210 divided by 131 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 654962.091
The remainder is 79 after subtracting 131 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 12:
The number 131 fits into 790 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 654962.0916
If we take 786 away from 790, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 131 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 654962.0916
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
131 can be fit into 400 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 654962.091603
Deduct 393 from 400 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 15:
If we divide 70 by 131, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 654962.091603
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
131 goes into 700 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 654962.09160305
If we subtract 655 from 700, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 654962.09160305, with a leftover of 4.5e-08.
