30472729 ÷ 218 
The aim is to understand the frequency of 218 in 30472729.

Let's proceed to step 1:
3 divided by 218 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 218

Going ahead to step 2:
The number 218 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 218

Step 3:
The number 218 fits into 304 1 times, leaving a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 218 from 304 to get 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 218

Step 4:
218 goes into 867 3 times with a remainder of 213.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 654 from 867, we get 213.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 218

On to step 5:
The number 218 fits into 2132 9 times, leaving a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we subtract 1962 from 2132, we get 170.
Take the next digit (7) from the dividend and append it to 170, then repeat: 1707 / 218

Going ahead to step 6:
When dividing 1707 by 218, we get 7 with a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 1397.0
If we subtract 1526 from 1707, we get 181.
Bring next digit (2) of the dividend behind the 181 and repeat the process: 1812 / 218

Step 7:
When dividing 1812 by 218, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 13978.0
Deduct 1744 from 1812 and we're left with 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 218

Let's proceed to step 8:
If we divide 689 by 218, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 139783.0
If we take 654 away from 689, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 218, we get 1 and a remainder of 132.
The next digit of our result is 1. 
Result so far: 139783.1
If we take 218 away from 350, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
The number 218 fits into 1320 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 139783.16
The remainder is 12 after subtracting 1308 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 218 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 139783.16
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
1200 divided by 218 is 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 139783.1605
The remainder is 110 after subtracting 1090 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
1100 divided by 218 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 139783.16055
If we subtract 1090 from 1100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 139783.16055, with a leftover of 1e-05.
