We look at the division of 443133 by 86 
The aim is to understand the frequency of 86 in 443133.

Going ahead to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 86

Moving on to step 2:
86 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 86

On to step 3:
If we divide 443 by 86, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 430 from 443 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 86

Moving on to step 4:
86 goes into 131 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 86 from 131 and we're left with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 86

Going ahead to step 5:
453 divided by 86 is 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 515.0
The remainder is 23 after subtracting 430 from 453.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 86

Moving on to step 6:
233 divided by 86 is 2 with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 5152.0
Subtract 172 from 233 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
86 can be fit into 610 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 5152.7
The remainder is 8 after subtracting 602 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 86, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 5152.7
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
When dividing 800 by 86, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 5152.709
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 5152.7093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 86 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5152.7093
If we take 0 away from 20, we end up 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.

Moving on to step 12:
When dividing 200 by 86, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 5152.709302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
86 goes into 280 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 5152.7093023
The remainder is 22 after subtracting 258 from 280.
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:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 5152.70930232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 5152.70930232, with a leftover of 4.8e-08.
