We look at the division of 672264 by 86 
The aim is to understand the frequency of 86 in 672264.

Advancing to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 86

Advancing to step 2:
86 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 86

Going ahead to step 3:
If we divide 672 by 86, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 602 from 672 to get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 86

Going ahead to step 4:
702 divided by 86 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 14 after subtracting 688 from 702.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 86

On to step 5:
The number 86 fits into 146 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 781.0
If we take 86 away from 146, we end up with 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 86

Step 6:
604 divided by 86 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7817.0
Deduct 602 from 604 and we're left 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 7:
20 divided by 86 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7817.0
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 8:
When dividing 200 by 86, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7817.02
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 7817.023
Subtract 258 from 280 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 10:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7817.0232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 86, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7817.02325
Subtract 430 from 480 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.

Moving on to step 12:
86 goes into 500 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 7817.023255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7817.023255, with a leftover of 7e-06.
