346073 divided by 81 
The aim is to understand the frequency of 81 in 346073.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 81

Let's proceed to step 2:
When dividing 34 by 81, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 81

Going ahead to step 3:
81 can be fit into 346 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 324 from 346 to get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 81

On to step 4:
81 can be fit into 220 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 162 from 220 leaves us with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 81

Going ahead to step 5:
81 goes into 587 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Deduct 567 from 587 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 81

Going ahead to step 6:
81 goes into 203 2 times with a remainder of 41.
The next digit of our result is 2. 
Result so far: 4272.0
If we take 162 away from 203, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
81 can be fit into 410 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4272.5
If we subtract 405 from 410, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 81 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4272.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
81 goes into 500 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 4272.506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
If we divide 140 by 81, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 4272.5061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
590 divided by 81 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 4272.50617
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
The number 81 fits into 230 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 4272.506172
Deduct 162 from 230 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
81 goes into 680 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4272.5061728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
81 goes into 320 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 4272.50617283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

In conclusion, the division gives 4272.50617283 with a balance of 7.7e-08.
