We look at the division of 84358540 by 411 
The aim is to understand the frequency of 411 in 84358540.

On to step 1:
If we divide 8 by 411, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 411

Advancing to step 2:
The number 411 fits into 84 0 times, leaving a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 411

Advancing to step 3:
The number 411 fits into 843 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 822 away from 843, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 411

Advancing to step 4:
411 can be fit into 215 0 times, resulting in a remainder of 215.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 215 to get 215.
Append the next digit (8) from the dividend to 215 and continue with: 2158 / 411

Going ahead to step 5:
If we divide 2158 by 411, we get 5 and a remainder of 103.
The next digit of our result is 5. 
Result so far: 205.0
The remainder is 103 after subtracting 2055 from 2158.
Append the next digit (5) from the dividend to 103 and continue with: 1035 / 411

Step 6:
When dividing 1035 by 411, we get 2 with a remainder of 213.
The next digit of our result is 2. 
Result so far: 2052.0
If we subtract 822 from 1035, we get 213.
Fetch the next digit (4) from the dividend, attach it to 213 and continue: 2134 / 411

Let's proceed to step 7:
411 goes into 2134 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 20525.0
Subtract 2055 from 2134 to get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 411

Moving on to step 8:
790 divided by 411 is 1 with a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 205251.0
Deduct 411 from 790 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 9:
The number 411 fits into 3790 9 times, leaving a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 205251.9
If we take 3699 away from 3790, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 10:
411 can be fit into 910 2 times, resulting in a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 205251.92
Subtracting 822 from 910 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
When dividing 880 by 411, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 205251.922
Deduct 822 from 880 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 205251.922 with a balance of 0.0058.
