19879794 divided by 115 
The aim is to understand the frequency of 115 in 19879794.

On to step 1:
115 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 115

Let's proceed to step 2:
The number 115 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 115

Moving on to step 3:
115 can be fit into 198 1 times, resulting in a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 115 from 198, we get 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 115

On to step 4:
115 goes into 837 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 32 after subtracting 805 from 837.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 115

Moving on to step 5:
115 can be fit into 329 2 times, resulting in a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 230 from 329 and we're left with 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 115

Advancing to step 6:
The number 115 fits into 997 8 times, leaving a remainder of 77.
The next digit of our result is 8. 
Result so far: 1728.0
Deduct 920 from 997 and we're left with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 115

On to step 7:
115 goes into 779 6 times with a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 17286.0
If we subtract 690 from 779, we get 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 115

On to step 8:
When dividing 894 by 115, we get 7 with a remainder of 89.
Record the quotient 7 as the next digit in the result. 
Result so far: 172867.0
If we subtract 805 from 894, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
When dividing 890 by 115, we get 7 with a remainder of 85.
Write down 7 as next digit of the result. 
Result so far: 172867.7
If we take 805 away from 890, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
The number 115 fits into 850 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 172867.77
If we subtract 805 from 850, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 172867.77 with a remaining 0.045.
