197346 ÷ 81 
The aim is to understand the frequency of 81 in 197346.

Step 1:
The number 81 fits into 1 0 times, leaving 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.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 81

Let's proceed to step 2:
81 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 81

Let's proceed to step 3:
197 divided by 81 is 2 with a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 162 away from 197, we end up with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 81

Advancing to step 4:
81 can be fit into 353 4 times, resulting in a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 324 away from 353, we end up with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 81

Let's proceed to step 5:
294 divided by 81 is 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
Subtract 243 from 294 to get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 81

Going ahead to step 6:
516 divided by 81 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 2436.0
If we subtract 486 from 516, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
When dividing 300 by 81, we get 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 2436.3
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 8:
570 divided by 81 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2436.37
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
30 divided by 81 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2436.37
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
81 can be fit into 300 3 times, resulting in a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 2436.3703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 11:
570 divided by 81 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2436.37037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
When dividing 30 by 81, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2436.37037
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
When dividing 300 by 81, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 2436.3703703
The remainder is 57 after subtracting 243 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2436.37037037
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 2436.37037037 and a remainder of 3e-09.
