We divide 195479 by 81
The aim is to understand the frequency of 81 in 195479.

Step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 81

Advancing to step 2:
The number 81 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 81

Let's proceed to step 3:
The number 81 fits into 195 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 162 from 195, we get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 81

Going ahead to step 4:
334 divided by 81 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 324 away from 334, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 81

Step 5:
When dividing 107 by 81, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 241.0
If we take 81 away from 107, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 81

Going ahead to step 6:
If we divide 269 by 81, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 2413.0
The remainder is 26 after subtracting 243 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
The number 81 fits into 260 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2413.3
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2413.32
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 2413.32
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 81 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 2413.3209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 11:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 2413.32098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
When dividing 620 by 81, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 2413.320987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 13:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 2413.3209876
If we take 486 away from 530, we end up 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.

Step 14:
When dividing 440 by 81, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2413.32098765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 2413.32098765 with a remainder of 3.5e-08.
