We're dividing 628994 by 86 
The aim is to understand the frequency of 86 in 628994.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 86

Going ahead to step 2:
If we divide 62 by 86, we get 0 and a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 86

Advancing to step 3:
The number 86 fits into 628 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 602 from 628 leaves us with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 86

Let's proceed to step 4:
86 goes into 269 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 73.0
The remainder is 11 after subtracting 258 from 269.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 86

Let's proceed to step 5:
86 can be fit into 119 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 731.0
The remainder is 33 after subtracting 86 from 119.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 86

Let's proceed to step 6:
The number 86 fits into 334 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 7313.0
Subtract 258 from 334 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 7313.8
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 7313.88
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 7313.88 with a balance of 0.032.
