We're dividing 677598 by 86 
The aim is to understand the frequency of 86 in 677598.

Going ahead to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 86

Advancing to step 2:
When dividing 67 by 86, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 86

Moving on to step 3:
677 divided by 86 is 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 75 after subtracting 602 from 677.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 86

Let's proceed to step 4:
86 goes into 755 8 times with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 688 from 755, we get 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 86

Advancing to step 5:
When dividing 679 by 86, we get 7 with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 787.0
Subtracting 602 from 679 leaves us with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 86

Advancing to step 6:
86 can be fit into 778 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 7879.0
If we take 774 away from 778, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
86 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7879.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 86, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 7879.04
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7879.046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 7879.0465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 86, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 7879.04651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 7879.046511
If we subtract 86 from 140, we 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.

The quotient of the division is 7879.046511, and the remainder is 5.4e-06.
