We're dividing 654600 by 86 
The aim is to understand the frequency of 86 in 654600.

On to step 1:
86 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 86

Step 2:
When dividing 65 by 86, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 86

Step 3:
86 goes into 654 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 602 from 654 to get 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 86

On to step 4:
86 can be fit into 526 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtract 516 from 526 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 86

Advancing to step 5:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we take 86 away from 100, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 86

Going ahead to step 6:
86 goes into 140 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 7611.0
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
The number 86 fits into 540 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7611.6
Subtract 516 from 540 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
86 goes into 240 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 7611.62
If we subtract 172 from 240, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7611.627
If we subtract 602 from 680, we get 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 10:
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: 7611.6279
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.

Step 11:
If we divide 60 by 86, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7611.6279
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 7611.627906
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 13:
If we divide 840 by 86, we get 9 and a remainder of 66.
The next digit of our result is 9. 
Result so far: 7611.6279069
If we take 774 away from 840, we end up 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.

Step 14:
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: 7611.62790697
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.

Our division results in 7611.62790697 with a remaining 5.8e-08.
