We're dividing 16978815 by 826 
The aim is to understand the frequency of 826 in 16978815.

Advancing to step 1:
The number 826 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 826

On to step 2:
826 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 826

Advancing to step 3:
826 goes into 169 0 times with a remainder of 169.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 169 after subtracting 0 from 169.
Include the next digit (7) from the dividend after 169, then repeat: 1697 / 826

Let's proceed to step 4:
The number 826 fits into 1697 2 times, leaving a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 45 after subtracting 1652 from 1697.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 826

Moving on to step 5:
826 goes into 458 0 times with a remainder of 458.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 458 to get 458.
Grab the next digit (8) from the dividend, add it to 458, then carry on: 4588 / 826

Let's proceed to step 6:
If we divide 4588 by 826, we get 5 and a remainder of 458.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Subtracting 4130 from 4588 leaves us with 458.
Fetch the next digit (1) from the dividend, attach it to 458 and continue: 4581 / 826

Going ahead to step 7:
When dividing 4581 by 826, we get 5 with a remainder of 451.
Use 5 as the next digit of our solution. 
Result so far: 2055.0
If we take 4130 away from 4581, we end up with 451.
Take the next digit (5) from the dividend and append it to 451, then repeat: 4515 / 826

Going ahead to step 8:
4515 divided by 826 is 5 with a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 20555.0
If we subtract 4130 from 4515, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 9:
3850 divided by 826 is 4 with a remainder of 546.
The next digit of our result is 4. 
Result so far: 20555.4
The remainder is 546 after subtracting 3304 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 10:
When dividing 5460 by 826, we get 6 with a remainder of 504.
The next digit of our result is 6. 
Result so far: 20555.46
Deduct 4956 from 5460 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 11:
If we divide 5040 by 826, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 20555.466
The remainder is 84 after subtracting 4956 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 20555.466 and a remainder of 0.0084.
