977246 ÷ 86 
The aim is to understand the frequency of 86 in 977246.

Let's proceed to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 86

On to step 2:
86 can be fit into 97 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 86 away from 97, we end up with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 86

Let's proceed to step 3:
If we divide 117 by 86, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 86 from 117 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 86

On to step 4:
The number 86 fits into 312 3 times, leaving a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we subtract 258 from 312, we get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 86

Advancing to step 5:
The number 86 fits into 544 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1136.0
If we subtract 516 from 544, we get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 86

Moving on to step 6:
86 can be fit into 286 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 11363.0
If we take 258 away from 286, 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.

Advancing to step 7:
280 divided by 86 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 11363.3
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.

Let's proceed to step 8:
86 goes into 220 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 11363.32
If we subtract 172 from 220, we 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.

Moving on to step 9:
86 can be fit into 480 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11363.325
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.

Let's proceed to step 10:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 11363.3255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 11363.3255 and a remainder of 0.0007.
