We look at the division of 35048 by 81 
The aim is to understand the frequency of 81 in 35048.

On to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 81

On to step 2:
35 divided by 81 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 81

Moving on to step 3:
If we divide 350 by 81, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 26 after subtracting 324 from 350.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 81

Step 4:
264 divided by 81 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 21 after subtracting 243 from 264.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 81

Going ahead to step 5:
If we divide 218 by 81, we get 2 and a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 432.0
Subtracting 162 from 218 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 6:
The number 81 fits into 560 6 times, leaving a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 432.6
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
740 divided by 81 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 432.69
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
If we divide 110 by 81, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 432.691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
81 can be fit into 290 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 432.6913
If we take 243 away from 290, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
When dividing 470 by 81, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 432.69135
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
81 goes into 650 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 432.691358
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 81, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 432.691358
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 81, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 432.69135802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 432.69135802 with a balance of 3.8e-08.
