672783 divided by 86 
The aim is to understand the frequency of 86 in 672783.

On to step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
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

Going ahead to step 2:
When dividing 67 by 86, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 86

On to step 3:
672 divided by 86 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 602 from 672, we get 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 86

Step 4:
The number 86 fits into 707 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 688 from 707 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 86

Let's proceed to step 5:
198 divided by 86 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 782.0
If we subtract 172 from 198, we get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 86

Moving on to step 6:
263 divided by 86 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 7823.0
If we subtract 258 from 263, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 86 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7823.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 86 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7823.05
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.

Moving on to step 9:
If we divide 700 by 86, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 7823.058
Subtracting 688 from 700 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
86 can be fit into 120 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 7823.0581
Deduct 86 from 120 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
If we divide 340 by 86, we get 3 and a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 7823.05813
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
820 divided by 86 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 7823.058139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
460 divided by 86 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 7823.0581395
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 7823.05813953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 7823.05813953, and the remainder is 4.2e-08.
