745365 divided by 81 
The aim is to understand the frequency of 81 in 745365.

Moving on to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 81

Moving on to step 2:
74 divided by 81 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 81

On to step 3:
If we divide 745 by 81, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 729 from 745 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 81

Let's proceed to step 4:
When dividing 163 by 81, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 1 after subtracting 162 from 163.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 81

On to step 5:
81 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 920.0
Subtract 0 from 16 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 81

Let's proceed to step 6:
When dividing 165 by 81, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 9202.0
If we take 162 away from 165, we end up 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 7:
If we divide 30 by 81, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9202.0
Subtract 0 from 30 to 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.

Step 8:
81 goes into 300 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 9202.03
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.

On to step 9:
81 goes into 570 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9202.037
If we take 567 away from 570, we end up 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 10:
30 divided by 81 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9202.037
Subtract 0 from 30 to 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 11:
The number 81 fits into 300 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 9202.03703
If we take 243 away from 300, we end up 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.

Step 12:
81 goes into 570 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 9202.037037
If we take 567 away from 570, we end up 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.

Let's proceed to step 13:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9202.037037
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.

Moving on to step 14:
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: 9202.03703703
If we take 243 away from 300, we end up 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.

In conclusion, the division gives 9202.03703703 with a balance of 5.7e-08.
