We divide 16948172 by 810
The aim is to understand the frequency of 810 in 16948172.

Advancing to step 1:
The number 810 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 810

Going ahead to step 2:
810 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 810

Let's proceed to step 3:
The number 810 fits into 169 0 times, leaving a remainder of 169.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 169 to get 169.
Append the next digit (4) from the dividend to 169 and continue with: 1694 / 810

Going ahead to step 4:
810 can be fit into 1694 2 times, resulting in a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1620 from 1694, we get 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 810

Step 5:
The number 810 fits into 748 0 times, leaving a remainder of 748.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 748 leaves us with 748.
Fetch the next digit (1) from the dividend, attach it to 748 and continue: 7481 / 810

Advancing to step 6:
When dividing 7481 by 810, we get 9 with a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 209.0
If we take 7290 away from 7481, we end up with 191.
Fetch the next digit (7) from the dividend, attach it to 191 and continue: 1917 / 810

Moving on to step 7:
The number 810 fits into 1917 2 times, leaving a remainder of 297.
Use 2 as the next digit of our solution. 
Result so far: 2092.0
Subtracting 1620 from 1917 leaves us with 297.
Bring next digit (2) of the dividend behind the 297 and repeat the process: 2972 / 810

Going ahead to step 8:
The number 810 fits into 2972 3 times, leaving a remainder of 542.
Use 3 as the next digit of our solution. 
Result so far: 20923.0
Subtract 2430 from 2972 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 9:
810 can be fit into 5420 6 times, resulting in a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 20923.6
If we subtract 4860 from 5420, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
810 goes into 5600 6 times with a remainder of 740.
Record the quotient 6 as the next digit in the result. 
Result so far: 20923.66
The remainder is 740 after subtracting 4860 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

After the division, we end up with 20923.66 and a remainder of 0.74.
