346258 ÷ 81 
The aim is to understand the frequency of 81 in 346258.

Moving on to step 1:
81 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 81

Let's proceed to step 2:
The number 81 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 81

Let's proceed to step 3:
If we divide 346 by 81, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 324 from 346 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 81

Let's proceed to step 4:
The number 81 fits into 222 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 60 after subtracting 162 from 222.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 81

Going ahead to step 5:
81 can be fit into 605 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 427.0
Subtract 567 from 605 to get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 81

Going ahead to step 6:
When dividing 388 by 81, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 4274.0
If we subtract 324 from 388, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
81 can be fit into 640 7 times, resulting in a remainder of 73.
The next digit of our result is 7. 
Result so far: 4274.7
If we take 567 away from 640, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
The number 81 fits into 730 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 4274.79
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
81 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4274.79
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 81, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4274.7901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
When dividing 190 by 81, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4274.79012
Subtract 162 from 190 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
When dividing 280 by 81, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 4274.790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
370 divided by 81 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4274.7901234
Subtract 324 from 370 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
460 divided by 81 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4274.79012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 4274.79012345 and a remainder of 5.5e-08.
