We look at the division of 85868481 by 818 
The aim is to understand the frequency of 818 in 85868481.

Advancing to step 1:
When dividing 8 by 818, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 818

Let's proceed to step 2:
If we divide 85 by 818, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 818

On to step 3:
If we divide 858 by 818, we get 1 and a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 818 from 858, we get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 818

On to step 4:
818 goes into 406 0 times with a remainder of 406.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 406, we end up with 406.
Fetch the next digit (8) from the dividend, attach it to 406 and continue: 4068 / 818

Going ahead to step 5:
818 can be fit into 4068 4 times, resulting in a remainder of 796.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtracting 3272 from 4068 leaves us with 796.
Append the next digit (4) from the dividend to 796 and continue with: 7964 / 818

On to step 6:
818 goes into 7964 9 times with a remainder of 602.
Use 9 as the next digit of our solution. 
Result so far: 1049.0
Subtract 7362 from 7964 to get 602.
Append the next digit (8) from the dividend to 602 and continue with: 6028 / 818

Advancing to step 7:
The number 818 fits into 6028 7 times, leaving a remainder of 302.
The number 7 becomes the next digit in our result. 
Result so far: 10497.0
Subtract 5726 from 6028 to get 302.
Append the next digit (1) from the dividend to 302 and continue with: 3021 / 818

Step 8:
818 goes into 3021 3 times with a remainder of 567.
The number 3 becomes the next digit in our result. 
Result so far: 104973.0
Subtract 2454 from 3021 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 9:
If we divide 5670 by 818, we get 6 and a remainder of 762.
Use 6 as the next digit of our solution. 
Result so far: 104973.6
The remainder is 762 after subtracting 4908 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Going ahead to step 10:
818 goes into 7620 9 times with a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 104973.69
Subtracting 7362 from 7620 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 11:
The number 818 fits into 2580 3 times, leaving a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 104973.693
If we subtract 2454 from 2580, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 12:
The number 818 fits into 1260 1 times, leaving a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 104973.6931
Subtracting 818 from 1260 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 13:
The number 818 fits into 4420 5 times, leaving a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 104973.69315
The remainder is 330 after subtracting 4090 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 14:
If we divide 3300 by 818, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 104973.693154
If we subtract 3272 from 3300, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
If we divide 280 by 818, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 104973.693154
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 16:
2800 divided by 818 is 3 with a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 104973.69315403
Subtracting 2454 from 2800 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

After the division, we end up with 104973.69315403 and a remainder of 3.46e-07.
