We look at the division of 10127511 by 818 
The aim is to understand the frequency of 818 in 10127511.

Let's proceed to step 1:
When dividing 1 by 818, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 818

Going ahead to step 2:
If we divide 10 by 818, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 818

Moving on to step 3:
If we divide 101 by 818, we get 0 and a remainder of 101.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Include the next digit (2) from the dividend after 101, then repeat: 1012 / 818

Step 4:
818 goes into 1012 1 times with a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 818 from 1012, we get 194.
Fetch the next digit (7) from the dividend, attach it to 194 and continue: 1947 / 818

Let's proceed to step 5:
The number 818 fits into 1947 2 times, leaving a remainder of 311.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1636 from 1947, we get 311.
Take the next digit (5) from the dividend and append it to 311, then repeat: 3115 / 818

Advancing to step 6:
818 can be fit into 3115 3 times, resulting in a remainder of 661.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 2454 from 3115 leaves us with 661.
Take the next digit (1) from the dividend and append it to 661, then repeat: 6611 / 818

On to step 7:
818 goes into 6611 8 times with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 1238.0
If we subtract 6544 from 6611, we get 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 818

Advancing to step 8:
671 divided by 818 is 0 with a remainder of 671.
Write down 0 as next digit of the result. 
Result so far: 12380.0
Subtracting 0 from 671 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Moving on to step 9:
818 goes into 6710 8 times with a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 12380.8
If we take 6544 away from 6710, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
The number 818 fits into 1660 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12380.82
If we take 1636 away from 1660, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
When dividing 240 by 818, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 12380.82
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
When dividing 2400 by 818, we get 2 with a remainder of 764.
The number 2 becomes the next digit in our result. 
Result so far: 12380.8202
The remainder is 764 after subtracting 1636 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 13:
7640 divided by 818 is 9 with a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 12380.82029
Subtract 7362 from 7640 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 14:
If we divide 2780 by 818, we get 3 and a remainder of 326.
Use 3 as the next digit of our solution. 
Result so far: 12380.820293
Subtract 2454 from 2780 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 15:
When dividing 3260 by 818, we get 3 with a remainder of 806.
The next digit of our result is 3. 
Result so far: 12380.8202933
If we take 2454 away from 3260, we end up with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Our division results in 12380.8202933 with a remaining 8.06e-06.
