We look at the division of 61462 by 81 
The aim is to understand the frequency of 81 in 61462.

Advancing to step 1:
6 divided by 81 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 81

On to step 2:
If we divide 61 by 81, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 81

Step 3:
The number 81 fits into 614 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 567 from 614 and we're left with 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 81

Advancing to step 4:
If we divide 476 by 81, we get 5 and a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 405 from 476 leaves us with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 81

Step 5:
81 can be fit into 712 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 758.0
If we take 648 away from 712, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 6:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 758.7
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 7:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 758.79
If we take 729 away from 730, we end up 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 8:
10 divided by 81 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 758.79
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 81, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 758.7901
Deduct 81 from 100 and we're left with 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 10:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 758.79012
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 81 fits into 280 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 758.790123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
If we divide 370 by 81, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 758.7901234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
When dividing 460 by 81, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 758.79012345
If we subtract 405 from 460, we get 55.
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 758.79012345, and the remainder is 5.5e-08.
