We divide 741325 by 81
The aim is to understand the frequency of 81 in 741325.

Let's proceed to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 81

Going ahead to step 2:
81 goes into 74 0 times 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 (1) from the dividend, attach it to 74 and continue: 741 / 81

On to step 3:
741 divided by 81 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 729 from 741 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 81

Step 4:
81 goes into 123 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 81 from 123, we get 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 81

Step 5:
The number 81 fits into 422 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 915.0
If we subtract 405 from 422, we get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 81

Step 6:
81 goes into 175 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 9152.0
Subtract 162 from 175 to 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.

Going ahead to step 7:
81 goes into 130 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 9152.1
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 9152.16
Subtracting 486 from 490 leaves us 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.

Step 9:
If we divide 40 by 81, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 9152.16
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
81 can be fit into 400 4 times, resulting in a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 9152.1604
Subtracting 324 from 400 leaves us 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.

Moving on to step 11:
When dividing 760 by 81, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9152.16049
If we take 729 away from 760, we end up 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.

Let's proceed to step 12:
310 divided by 81 is 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 9152.160493
The remainder is 67 after subtracting 243 from 310.
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 13:
If we divide 670 by 81, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 9152.1604938
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
If we divide 220 by 81, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 9152.16049382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 9152.16049382 with a remainder of 5.8e-08.
