We look at the division of 69665775 by 818 
The aim is to understand the frequency of 818 in 69665775.

Going ahead to step 1:
When dividing 6 by 818, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 818

Advancing to step 2:
When dividing 69 by 818, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 818

On to step 3:
When dividing 696 by 818, we get 0 with a remainder of 696.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 696 after subtracting 0 from 696.
Include the next digit (6) from the dividend after 696, then repeat: 6966 / 818

Let's proceed to step 4:
6966 divided by 818 is 8 with a remainder of 422.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6544 from 6966, we get 422.
Take the next digit (5) from the dividend and append it to 422, then repeat: 4225 / 818

Advancing to step 5:
When dividing 4225 by 818, we get 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 4090 from 4225, we get 135.
Bring next digit (7) of the dividend behind the 135 and repeat the process: 1357 / 818

Step 6:
1357 divided by 818 is 1 with a remainder of 539.
The next digit of our result is 1. 
Result so far: 851.0
Subtracting 818 from 1357 leaves us with 539.
Grab the next digit (7) from the dividend, add it to 539, then carry on: 5397 / 818

Moving on to step 7:
818 can be fit into 5397 6 times, resulting in a remainder of 489.
The next digit of our result is 6. 
Result so far: 8516.0
If we take 4908 away from 5397, we end up with 489.
Grab the next digit (5) from the dividend, add it to 489, then carry on: 4895 / 818

Step 8:
818 goes into 4895 5 times with a remainder of 805.
The number 5 becomes the next digit in our result. 
Result so far: 85165.0
If we take 4090 away from 4895, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 9:
When dividing 8050 by 818, we get 9 with a remainder of 688.
The number 9 becomes the next digit in our result. 
Result so far: 85165.9
If we subtract 7362 from 8050, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 10:
When dividing 6880 by 818, we get 8 with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 85165.98
Subtract 6544 from 6880 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
When dividing 3360 by 818, we get 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 85165.984
Subtracting 3272 from 3360 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
If we divide 880 by 818, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 85165.9841
Subtract 818 from 880 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
818 can be fit into 620 0 times, resulting in a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 85165.9841
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
When dividing 6200 by 818, we get 7 with a remainder of 474.
Put 7 as the next digit of the answer. 
Result so far: 85165.984107
The remainder is 474 after subtracting 5726 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 15:
The number 818 fits into 4740 5 times, leaving a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 85165.9841075
If we subtract 4090 from 4740, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 16:
818 goes into 6500 7 times with a remainder of 774.
Put 7 as the next digit of the answer. 
Result so far: 85165.98410757
If we subtract 5726 from 6500, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

After the division, we end up with 85165.98410757 and a remainder of 7.74e-07.
