We divide 199567 by 81
The aim is to understand the frequency of 81 in 199567.

Let's proceed to step 1:
1 divided by 81 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 81

Going ahead to step 2:
19 divided by 81 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 81

Going ahead to step 3:
When dividing 199 by 81, we get 2 with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 37 after subtracting 162 from 199.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 81

On to step 4:
375 divided by 81 is 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 324 from 375 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 81

Moving on to step 5:
516 divided by 81 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 246.0
Subtract 486 from 516 to get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 81

Step 6:
If we divide 307 by 81, we get 3 and a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 2463.0
The remainder is 64 after subtracting 243 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
81 goes into 640 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 2463.7
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 8:
When dividing 730 by 81, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2463.79
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
81 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2463.79
Subtracting 0 from 10 leaves us 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.

Step 10:
If we divide 100 by 81, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2463.7901
If we subtract 81 from 100, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2463.79012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
81 can be fit into 280 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 2463.790123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
370 divided by 81 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 2463.7901234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
81 goes into 460 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 2463.79012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 2463.79012345, and the remainder is 5.5e-08.
