We're dividing 962669 by 81 
The aim is to understand the frequency of 81 in 962669.

Moving on to step 1:
81 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 81

Let's proceed to step 2:
96 divided by 81 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 81 from 96, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 81

Moving on to step 3:
The number 81 fits into 152 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 81 away from 152, we end up with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 81

Step 4:
The number 81 fits into 716 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 118.0
Subtracting 648 from 716 leaves us with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 81

Step 5:
686 divided by 81 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 1188.0
Subtracting 648 from 686 leaves us with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 81

Moving on to step 6:
81 goes into 389 4 times with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 11884.0
If we subtract 324 from 389, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
The number 81 fits into 650 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 11884.8
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.

Going ahead to step 8:
When dividing 20 by 81, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11884.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 81, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 11884.802
Subtract 162 from 200 to 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 10:
The number 81 fits into 380 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 11884.8024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
81 goes into 560 6 times with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 11884.80246
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.

Advancing to step 12:
If we divide 740 by 81, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 11884.802469
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
If we divide 110 by 81, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 11884.8024691
Deduct 81 from 110 and we're left 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.

Let's proceed to step 14:
290 divided by 81 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 11884.80246913
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 11884.80246913 with a remainder of 4.7e-08.
