We're dividing 45393808 by 219 
The aim is to understand the frequency of 219 in 45393808.

Going ahead to step 1:
4 divided by 219 is 0 with 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.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 219

Going ahead to step 2:
The number 219 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 219

Step 3:
453 divided by 219 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 438 from 453 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 219

On to step 4:
219 goes into 159 0 times with a remainder of 159.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 159 after subtracting 0 from 159.
Append the next digit (3) from the dividend to 159 and continue with: 1593 / 219

Advancing to step 5:
219 goes into 1593 7 times with a remainder of 60.
The next digit of our result is 7. 
Result so far: 207.0
Subtract 1533 from 1593 to get 60.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 219

Advancing to step 6:
When dividing 608 by 219, we get 2 with a remainder of 170.
Use 2 as the next digit of our solution. 
Result so far: 2072.0
The remainder is 170 after subtracting 438 from 608.
Bring next digit (0) of the dividend behind the 170 and repeat the process: 1700 / 219

Moving on to step 7:
219 can be fit into 1700 7 times, resulting in a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 20727.0
If we take 1533 away from 1700, we end up with 167.
Fetch the next digit (8) from the dividend, attach it to 167 and continue: 1678 / 219

Advancing to step 8:
If we divide 1678 by 219, we get 7 and a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 207277.0
The remainder is 145 after subtracting 1533 from 1678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
If we divide 1450 by 219, we get 6 and a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 207277.6
Subtract 1314 from 1450 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
1360 divided by 219 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 207277.66
If we take 1314 away from 1360, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 207277.66 and a remainder of 0.046.
