We look at the division of 78280289 by 418 
The aim is to understand the frequency of 418 in 78280289.

Advancing to step 1:
If we divide 7 by 418, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 418

Going ahead to step 2:
78 divided by 418 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 418

Step 3:
When dividing 782 by 418, we get 1 with a remainder of 364.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 418 from 782 leaves us with 364.
Bring next digit (8) of the dividend behind the 364 and repeat the process: 3648 / 418

Moving on to step 4:
418 can be fit into 3648 8 times, resulting in a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3344 from 3648 leaves us with 304.
Take the next digit (0) from the dividend and append it to 304, then repeat: 3040 / 418

Let's proceed to step 5:
3040 divided by 418 is 7 with a remainder of 114.
The next digit of our result is 7. 
Result so far: 187.0
Subtracting 2926 from 3040 leaves us with 114.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 418

On to step 6:
When dividing 1142 by 418, we get 2 with a remainder of 306.
Record the quotient 2 as the next digit in the result. 
Result so far: 1872.0
The remainder is 306 after subtracting 836 from 1142.
Append the next digit (8) from the dividend to 306 and continue with: 3068 / 418

Advancing to step 7:
The number 418 fits into 3068 7 times, leaving a remainder of 142.
The number 7 becomes the next digit in our result. 
Result so far: 18727.0
Subtract 2926 from 3068 to get 142.
Include the next digit (9) from the dividend after 142, then repeat: 1429 / 418

Moving on to step 8:
When dividing 1429 by 418, we get 3 with a remainder of 175.
Record the quotient 3 as the next digit in the result. 
Result so far: 187273.0
Deduct 1254 from 1429 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 9:
The number 418 fits into 1750 4 times, leaving a remainder of 78.
The next digit of our result is 4. 
Result so far: 187273.4
Deduct 1672 from 1750 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
If we divide 780 by 418, we get 1 and a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 187273.41
Subtracting 418 from 780 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 11:
418 goes into 3620 8 times with a remainder of 276.
The next digit of our result is 8. 
Result so far: 187273.418
If we subtract 3344 from 3620, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 12:
418 goes into 2760 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 187273.4186
The remainder is 252 after subtracting 2508 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 13:
The number 418 fits into 2520 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 187273.41866
The remainder is 12 after subtracting 2508 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 187273.41866, and the remainder is 1.2e-05.
