We look at the division of 42879358 by 219 
The aim is to understand the frequency of 219 in 42879358.

Going ahead to step 1:
219 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 219

Let's proceed to step 2:
219 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 219

Step 3:
When dividing 428 by 219, we get 1 with a remainder of 209.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 219 from 428, we get 209.
Fetch the next digit (7) from the dividend, attach it to 209 and continue: 2097 / 219

Moving on to step 4:
The number 219 fits into 2097 9 times, leaving a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 1971 from 2097 to get 126.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 219

Going ahead to step 5:
1269 divided by 219 is 5 with a remainder of 174.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtracting 1095 from 1269 leaves us with 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 219

Step 6:
If we divide 1743 by 219, we get 7 and a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 1957.0
If we take 1533 away from 1743, we end up with 210.
Include the next digit (5) from the dividend after 210, then repeat: 2105 / 219

Let's proceed to step 7:
The number 219 fits into 2105 9 times, leaving a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 19579.0
Subtract 1971 from 2105 to get 134.
Include the next digit (8) from the dividend after 134, then repeat: 1348 / 219

Moving on to step 8:
The number 219 fits into 1348 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 195796.0
Deduct 1314 from 1348 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 219 fits into 340 1 times, leaving a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 195796.1
If we take 219 away from 340, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
219 can be fit into 1210 5 times, resulting in a remainder of 115.
The next digit of our result is 5. 
Result so far: 195796.15
If we subtract 1095 from 1210, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
219 goes into 1150 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 195796.155
If we take 1095 away from 1150, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 195796.155 with a balance of 0.0055.
