742044 ÷ 81 
The aim is to understand the frequency of 81 in 742044.

On to step 1:
81 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 81

Let's proceed to step 2:
81 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 81

Advancing to step 3:
When dividing 742 by 81, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 13 after subtracting 729 from 742.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 81

Step 4:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtract 81 from 130 to get 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 81

Let's proceed to step 5:
81 can be fit into 494 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 916.0
The remainder is 8 after subtracting 486 from 494.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 81

Step 6:
If we divide 84 by 81, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 9161.0
If we subtract 81 from 84, 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.

Moving on to step 7:
30 divided by 81 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9161.0
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.

Moving on to step 8:
300 divided by 81 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 9161.03
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
If we divide 570 by 81, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 9161.037
Subtracting 567 from 570 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
81 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 9161.037
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 81 fits into 300 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 9161.03703
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
81 can be fit into 570 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 9161.037037
Subtracting 567 from 570 leaves us with 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 13:
81 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9161.037037
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
81 goes into 300 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 9161.03703703
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.

The quotient of the division is 9161.03703703, and the remainder is 5.7e-08.
