We look at the division of 48718742 by 219 
The aim is to understand the frequency of 219 in 48718742.

On to step 1:
4 divided by 219 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 219

Let's proceed to step 2:
219 can be fit into 48 0 times, resulting in a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 219

Moving on to step 3:
219 goes into 487 2 times with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 438 away from 487, we end up with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 219

Let's proceed to step 4:
If we divide 491 by 219, we get 2 and a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 438 from 491 leaves us with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 219

Step 5:
If we divide 538 by 219, we get 2 and a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Subtract 438 from 538 to get 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 219

Let's proceed to step 6:
219 can be fit into 1007 4 times, resulting in a remainder of 131.
Put 4 as the next digit of the answer. 
Result so far: 2224.0
The remainder is 131 after subtracting 876 from 1007.
Include the next digit (4) from the dividend after 131, then repeat: 1314 / 219

On to step 7:
The number 219 fits into 1314 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 22246.0
The remainder is 0 after subtracting 1314 from 1314.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 219

On to step 8:
2 divided by 219 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 222460.0
Subtract 0 from 2 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.

Step 9:
219 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 222460.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
The number 219 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 222460.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 222460.0, with a leftover of 0.2.
