626659 ÷ 86 
The aim is to understand the frequency of 86 in 626659.

Advancing to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 86

Let's proceed to step 2:
When dividing 62 by 86, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 86

Going ahead to step 3:
The number 86 fits into 626 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 602 from 626 to get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 86

Moving on to step 4:
If we divide 246 by 86, we get 2 and a remainder of 74.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 172 from 246 and we're left with 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 86

Let's proceed to step 5:
745 divided by 86 is 8 with a remainder of 57.
The next digit of our result is 8. 
Result so far: 728.0
Subtracting 688 from 745 leaves us with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 86

On to step 6:
The number 86 fits into 579 6 times, leaving a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 7286.0
Deduct 516 from 579 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
86 can be fit into 630 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 7286.7
Subtract 602 from 630 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.

Advancing to step 8:
280 divided by 86 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 7286.73
If we subtract 258 from 280, we 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.

On to step 9:
When dividing 220 by 86, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7286.732
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.

On to step 10:
86 goes into 480 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7286.7325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
86 can be fit into 500 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7286.73255
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.

Our division results in 7286.73255 with a remaining 7e-05.
