Let's divide 58456243 by 218
The aim is to understand the frequency of 218 in 58456243.

Step 1:
218 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 218

Going ahead to step 2:
The number 218 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 218

Step 3:
When dividing 584 by 218, we get 2 with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 436 from 584 leaves us with 148.
Append the next digit (5) from the dividend to 148 and continue with: 1485 / 218

Step 4:
1485 divided by 218 is 6 with a remainder of 177.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 1308 from 1485 to get 177.
Append the next digit (6) from the dividend to 177 and continue with: 1776 / 218

Moving on to step 5:
1776 divided by 218 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 268.0
Subtracting 1744 from 1776 leaves us with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 218

Moving on to step 6:
When dividing 322 by 218, we get 1 with a remainder of 104.
The next digit of our result is 1. 
Result so far: 2681.0
Subtract 218 from 322 to get 104.
Append the next digit (4) from the dividend to 104 and continue with: 1044 / 218

Moving on to step 7:
218 can be fit into 1044 4 times, resulting in a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 26814.0
If we take 872 away from 1044, we end up with 172.
Take the next digit (3) from the dividend and append it to 172, then repeat: 1723 / 218

On to step 8:
218 goes into 1723 7 times with a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 268147.0
The remainder is 197 after subtracting 1526 from 1723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 9:
The number 218 fits into 1970 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 268147.9
Deduct 1962 from 1970 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 218 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 268147.9
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
218 can be fit into 800 3 times, resulting in a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 268147.903
Subtract 654 from 800 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 12:
When dividing 1460 by 218, we get 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 268147.9036
Deduct 1308 from 1460 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 13:
218 goes into 1520 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 268147.90366
If we take 1308 away from 1520, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 268147.90366, with a leftover of 0.000212.
