We're dividing 683547 by 86 
The aim is to understand the frequency of 86 in 683547.

Moving on to step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 86

On to step 2:
86 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 86

Step 3:
86 goes into 683 7 times with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 602 from 683, we get 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 86

Step 4:
If we divide 815 by 86, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 774 from 815 leaves us with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 86

Moving on to step 5:
If we divide 414 by 86, we get 4 and a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 794.0
If we take 344 away from 414, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 86

Going ahead to step 6:
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: 7948.0
Subtracting 688 from 707 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
86 can be fit into 190 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 7948.2
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
86 can be fit into 180 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 7948.22
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 7948.22, and the remainder is 0.008.
