We look at the division of 12250024 by 818 
The aim is to understand the frequency of 818 in 12250024.

Step 1:
818 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 818

Advancing to step 2:
12 divided by 818 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 818

Advancing to step 3:
The number 818 fits into 122 0 times, leaving a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 818

On to step 4:
If we divide 1225 by 818, we get 1 and a remainder of 407.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 407 after subtracting 818 from 1225.
Take the next digit (0) from the dividend and append it to 407, then repeat: 4070 / 818

On to step 5:
The number 818 fits into 4070 4 times, leaving a remainder of 798.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 3272 from 4070 leaves us with 798.
Grab the next digit (0) from the dividend, add it to 798, then carry on: 7980 / 818

Step 6:
818 goes into 7980 9 times with a remainder of 618.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 7362 from 7980 to get 618.
Include the next digit (2) from the dividend after 618, then repeat: 6182 / 818

Step 7:
If we divide 6182 by 818, we get 7 and a remainder of 456.
The next digit of our result is 7. 
Result so far: 1497.0
Subtracting 5726 from 6182 leaves us with 456.
Append the next digit (4) from the dividend to 456 and continue with: 4564 / 818

Going ahead to step 8:
818 goes into 4564 5 times with a remainder of 474.
The number 5 becomes the next digit in our result. 
Result so far: 14975.0
Subtracting 4090 from 4564 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 9:
818 goes into 4740 5 times with a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 14975.5
If we take 4090 away from 4740, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 10:
When dividing 6500 by 818, we get 7 with a remainder of 774.
Record the quotient 7 as the next digit in the result. 
Result so far: 14975.57
Deduct 5726 from 6500 and we're left with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 11:
The number 818 fits into 7740 9 times, leaving a remainder of 378.
Use 9 as the next digit of our solution. 
Result so far: 14975.579
If we subtract 7362 from 7740, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 12:
818 goes into 3780 4 times with a remainder of 508.
The next digit of our result is 4. 
Result so far: 14975.5794
Deduct 3272 from 3780 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 13:
818 can be fit into 5080 6 times, resulting in a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 14975.57946
If we subtract 4908 from 5080, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 14:
818 can be fit into 1720 2 times, resulting in a remainder of 84.
The next digit of our result is 2. 
Result so far: 14975.579462
Deduct 1636 from 1720 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
840 divided by 818 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 14975.5794621
If we take 818 away from 840, we end up 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.

On to step 16:
The number 818 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 14975.5794621
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 14975.5794621 with a balance of 2.2e-07.
