We look at the division of 133798 by 86 
The aim is to understand the frequency of 86 in 133798.

On to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 86

Moving on to step 2:
86 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 86

On to step 3:
86 can be fit into 133 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 47 after subtracting 86 from 133.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 86

Step 4:
The number 86 fits into 477 5 times, leaving a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 430 from 477, we get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 86

On to step 5:
If we divide 479 by 86, we get 5 and a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
The remainder is 49 after subtracting 430 from 479.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 86

Step 6:
When dividing 498 by 86, we get 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 1555.0
Subtracting 430 from 498 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
When dividing 680 by 86, we get 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 1555.7
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
If we divide 780 by 86, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1555.79
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1555.79
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 86, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 1555.7906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
840 divided by 86 is 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 1555.79069
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 1555.790697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
580 divided by 86 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1555.7906976
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1555.79069767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 1555.79069767 with a balance of 3.8e-08.
