732442 divided by 81 
The aim is to understand the frequency of 81 in 732442.

On to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 81

On to step 2:
When dividing 73 by 81, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 81

Step 3:
When dividing 732 by 81, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 729 away from 732, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 81

Going ahead to step 4:
81 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 81

Moving on to step 5:
344 divided by 81 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 904.0
Subtract 324 from 344 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 81

Advancing to step 6:
81 goes into 202 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9042.0
The remainder is 40 after subtracting 162 from 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
If we divide 400 by 81, we get 4 and a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 9042.4
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
When dividing 760 by 81, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 9042.49
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 9042.493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
When dividing 670 by 81, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 9042.4938
Deduct 648 from 670 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
81 can be fit into 220 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 9042.49382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
580 divided by 81 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 9042.493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
81 can be fit into 130 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 9042.4938271
If we subtract 81 from 130, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 9042.49382716
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 9042.49382716 with a remaining 4e-09.
