We divide 19216517 by 812
The aim is to understand the frequency of 812 in 19216517.

Going ahead to step 1:
When dividing 1 by 812, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 812

Moving on to step 2:
812 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 812

Step 3:
192 divided by 812 is 0 with a remainder of 192.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 192, we get 192.
Grab the next digit (1) from the dividend, add it to 192, then carry on: 1921 / 812

On to step 4:
812 goes into 1921 2 times with a remainder of 297.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1624 from 1921 to get 297.
Bring next digit (6) of the dividend behind the 297 and repeat the process: 2976 / 812

On to step 5:
812 goes into 2976 3 times with a remainder of 540.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 2436 from 2976 to get 540.
Append the next digit (5) from the dividend to 540 and continue with: 5405 / 812

Moving on to step 6:
5405 divided by 812 is 6 with a remainder of 533.
Put 6 as the next digit of the answer. 
Result so far: 236.0
The remainder is 533 after subtracting 4872 from 5405.
Take the next digit (1) from the dividend and append it to 533, then repeat: 5331 / 812

Advancing to step 7:
812 goes into 5331 6 times with a remainder of 459.
Use 6 as the next digit of our solution. 
Result so far: 2366.0
Subtract 4872 from 5331 to get 459.
Append the next digit (7) from the dividend to 459 and continue with: 4597 / 812

Advancing to step 8:
812 goes into 4597 5 times with a remainder of 537.
The number 5 becomes the next digit in our result. 
Result so far: 23665.0
The remainder is 537 after subtracting 4060 from 4597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Step 9:
812 goes into 5370 6 times with a remainder of 498.
Write down 6 as next digit of the result. 
Result so far: 23665.6
If we subtract 4872 from 5370, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 10:
If we divide 4980 by 812, we get 6 and a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 23665.66
If we subtract 4872 from 4980, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 23665.66, and the remainder is 0.108.
