We're dividing 634804 by 86 
The aim is to understand the frequency of 86 in 634804.

Step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 86

Going ahead to step 2:
The number 86 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 86

On to step 3:
If we divide 634 by 86, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 602 from 634 leaves us with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 86

Moving on to step 4:
The number 86 fits into 328 3 times, leaving a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 258 from 328, we get 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 86

On to step 5:
86 can be fit into 700 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 738.0
The remainder is 12 after subtracting 688 from 700.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 86

Going ahead to step 6:
When dividing 124 by 86, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 7381.0
Subtract 86 from 124 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 7381.4
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 7381.44
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7381.44, with a leftover of 0.016.
