Let's divide 198632 by 81
The aim is to understand the frequency of 81 in 198632.

Step 1:
81 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 81

Going ahead to step 2:
If we divide 19 by 81, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 81

Advancing to step 3:
If we divide 198 by 81, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 162 from 198 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 81

On to step 4:
If we divide 366 by 81, we get 4 and a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 42 after subtracting 324 from 366.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 81

Step 5:
423 divided by 81 is 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 245.0
The remainder is 18 after subtracting 405 from 423.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 81

Moving on to step 6:
182 divided by 81 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2452.0
Subtract 162 from 182 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2452.2
If we subtract 162 from 200, we 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.

Step 8:
When dividing 380 by 81, we get 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2452.24
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
When dividing 560 by 81, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 2452.246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
When dividing 740 by 81, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2452.2469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
81 goes into 110 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 2452.24691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2452.246913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
81 goes into 470 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 2452.2469135
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 14:
81 can be fit into 650 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2452.24691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 2452.24691358 with a balance of 2e-09.
