Let's divide 48978 by 86
The aim is to understand the frequency of 86 in 48978.

Advancing to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 86

Moving on to step 2:
86 can be fit into 48 0 times, resulting in a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 86

Going ahead to step 3:
When dividing 489 by 86, we get 5 with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 430 from 489, we get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 86

Moving on to step 4:
When dividing 597 by 86, we get 6 with a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 516 from 597 and we're left with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 86

Advancing to step 5:
When dividing 818 by 86, we get 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 569.0
Subtracting 774 from 818 leaves us with 44.
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 6:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 569.5
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 569.51
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 86 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 569.511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 569.511 with a remainder of 0.0054.
