79198251 ÷ 813 
The aim is to understand the frequency of 813 in 79198251.

Advancing to step 1:
813 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 813

Let's proceed to step 2:
When dividing 79 by 813, we get 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 813

Let's proceed to step 3:
When dividing 791 by 813, we get 0 with a remainder of 791.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 791, we get 791.
Append the next digit (9) from the dividend to 791 and continue with: 7919 / 813

On to step 4:
7919 divided by 813 is 9 with a remainder of 602.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 602 after subtracting 7317 from 7919.
Bring next digit (8) of the dividend behind the 602 and repeat the process: 6028 / 813

Step 5:
If we divide 6028 by 813, we get 7 and a remainder of 337.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 337 after subtracting 5691 from 6028.
Bring next digit (2) of the dividend behind the 337 and repeat the process: 3372 / 813

Step 6:
If we divide 3372 by 813, we get 4 and a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 974.0
If we take 3252 away from 3372, we end up with 120.
Include the next digit (5) from the dividend after 120, then repeat: 1205 / 813

Advancing to step 7:
The number 813 fits into 1205 1 times, leaving a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 9741.0
The remainder is 392 after subtracting 813 from 1205.
Take the next digit (1) from the dividend and append it to 392, then repeat: 3921 / 813

Step 8:
When dividing 3921 by 813, we get 4 with a remainder of 669.
Put 4 as the next digit of the answer. 
Result so far: 97414.0
If we subtract 3252 from 3921, we get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Going ahead to step 9:
6690 divided by 813 is 8 with a remainder of 186.
Use 8 as the next digit of our solution. 
Result so far: 97414.8
If we subtract 6504 from 6690, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
When dividing 1860 by 813, we get 2 with a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 97414.82
The remainder is 234 after subtracting 1626 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
The number 813 fits into 2340 2 times, leaving a remainder of 714.
The number 2 becomes the next digit in our result. 
Result so far: 97414.822
Subtract 1626 from 2340 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

The final outcome is 97414.822, with a leftover of 0.0714.
