19906912 ÷ 218 
The aim is to understand the frequency of 218 in 19906912.

Step 1:
1 divided by 218 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 218

Step 2:
If we divide 19 by 218, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 218

Going ahead to step 3:
If we divide 199 by 218, we get 0 and a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 199 and we're left with 199.
Bring next digit (0) of the dividend behind the 199 and repeat the process: 1990 / 218

Step 4:
If we divide 1990 by 218, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 28 after subtracting 1962 from 1990.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 218

Advancing to step 5:
218 can be fit into 286 1 times, resulting in a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 218 from 286, we get 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 218

Let's proceed to step 6:
When dividing 689 by 218, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 913.0
Subtract 654 from 689 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 218

Let's proceed to step 7:
If we divide 351 by 218, we get 1 and a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 9131.0
The remainder is 133 after subtracting 218 from 351.
Grab the next digit (2) from the dividend, add it to 133, then carry on: 1332 / 218

Let's proceed to step 8:
1332 divided by 218 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 91316.0
If we subtract 1308 from 1332, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 218, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 91316.1
Deduct 218 from 240 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 218, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 91316.11
Subtract 218 from 220 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 91316.11 with a balance of 0.002.
