16927966 divided by 813 
The aim is to understand the frequency of 813 in 16927966.

Moving on to step 1:
The number 813 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 813

On to step 2:
813 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
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 / 813

Going ahead to step 3:
The number 813 fits into 169 0 times, leaving a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 169, we end up with 169.
Bring next digit (2) of the dividend behind the 169 and repeat the process: 1692 / 813

Going ahead to step 4:
If we divide 1692 by 813, we get 2 and a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1626 from 1692 and we're left with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 813

Let's proceed to step 5:
813 can be fit into 667 0 times, resulting in a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 667 and we're left with 667.
Take the next digit (9) from the dividend and append it to 667, then repeat: 6679 / 813

Step 6:
813 goes into 6679 8 times with a remainder of 175.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Deduct 6504 from 6679 and we're left with 175.
Bring next digit (6) of the dividend behind the 175 and repeat the process: 1756 / 813

Advancing to step 7:
If we divide 1756 by 813, we get 2 and a remainder of 130.
The next digit of our result is 2. 
Result so far: 2082.0
Subtracting 1626 from 1756 leaves us with 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 813

On to step 8:
If we divide 1306 by 813, we get 1 and a remainder of 493.
Write down 1 as next digit of the result. 
Result so far: 20821.0
Subtracting 813 from 1306 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 9:
If we divide 4930 by 813, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 20821.6
Subtract 4878 from 4930 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
If we divide 520 by 813, we get 0 and a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 20821.6
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 11:
The number 813 fits into 5200 6 times, leaving a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 20821.606
If we take 4878 away from 5200, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 12:
If we divide 3220 by 813, we get 3 and a remainder of 781.
Use 3 as the next digit of our solution. 
Result so far: 20821.6063
Subtracting 2439 from 3220 leaves us with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Advancing to step 13:
813 goes into 7810 9 times with a remainder of 493.
Use 9 as the next digit of our solution. 
Result so far: 20821.60639
If we subtract 7317 from 7810, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 14:
The number 813 fits into 4930 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 20821.606396
If we subtract 4878 from 4930, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
When dividing 520 by 813, we get 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 20821.606396
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 16:
813 goes into 5200 6 times with a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 20821.60639606
If we take 4878 away from 5200, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final result is 20821.60639606 with a remainder of 3.22e-07.
