742622 ÷ 81 
The aim is to understand the frequency of 81 in 742622.

Moving on to step 1:
7 divided by 81 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 81

Advancing to step 2:
When dividing 74 by 81, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 81

Step 3:
The number 81 fits into 742 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 729 away from 742, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 81

Moving on to step 4:
136 divided by 81 is 1 with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 81 from 136 to get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 81

On to step 5:
81 can be fit into 552 6 times, resulting in a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 916.0
Subtracting 486 from 552 leaves us with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 81

On to step 6:
If we divide 662 by 81, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 9168.0
Subtracting 648 from 662 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
81 goes into 140 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 9168.1
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
The number 81 fits into 590 7 times, leaving a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 9168.17
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
230 divided by 81 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 9168.172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
81 goes into 680 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9168.1728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
320 divided by 81 is 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 9168.17283
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 9168.172839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
81 goes into 410 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9168.1728395
Subtract 405 from 410 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9168.1728395
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 9168.1728395 with a balance of 5e-08.
