Let's divide 429984 by 81
The aim is to understand the frequency of 81 in 429984.

Let's proceed to step 1:
81 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 81

Let's proceed to step 2:
81 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 81

Moving on to step 3:
The number 81 fits into 429 5 times, leaving a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 405 from 429 to get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 81

Going ahead to step 4:
When dividing 249 by 81, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 243 from 249, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 81

Moving on to step 5:
When dividing 68 by 81, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 530.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 81

Let's proceed to step 6:
81 can be fit into 684 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 5308.0
Subtract 648 from 684 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
If we divide 360 by 81, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5308.4
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 81 fits into 360 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5308.44
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 5308.44 with a balance of 0.036.
