23197426 divided by 815 
The aim is to understand the frequency of 815 in 23197426.

Going ahead to step 1:
When dividing 2 by 815, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 815

Let's proceed to step 2:
The number 815 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 815

Let's proceed to step 3:
815 can be fit into 231 0 times, resulting in a remainder of 231.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 231, we get 231.
Grab the next digit (9) from the dividend, add it to 231, then carry on: 2319 / 815

Let's proceed to step 4:
When dividing 2319 by 815, we get 2 with a remainder of 689.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1630 from 2319 and we're left with 689.
Take the next digit (7) from the dividend and append it to 689, then repeat: 6897 / 815

Let's proceed to step 5:
815 goes into 6897 8 times with a remainder of 377.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 6520 away from 6897, we end up with 377.
Take the next digit (4) from the dividend and append it to 377, then repeat: 3774 / 815

Step 6:
3774 divided by 815 is 4 with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 284.0
If we subtract 3260 from 3774, we get 514.
Fetch the next digit (2) from the dividend, attach it to 514 and continue: 5142 / 815

Step 7:
815 goes into 5142 6 times with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 2846.0
If we subtract 4890 from 5142, we get 252.
Append the next digit (6) from the dividend to 252 and continue with: 2526 / 815

Advancing to step 8:
815 goes into 2526 3 times with a remainder of 81.
The next digit of our result is 3. 
Result so far: 28463.0
Subtracting 2445 from 2526 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
815 can be fit into 810 0 times, resulting in a remainder of 810.
Write down 0 as next digit of the result. 
Result so far: 28463.0
If we subtract 0 from 810, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 10:
815 can be fit into 8100 9 times, resulting in a remainder of 765.
The number 9 becomes the next digit in our result. 
Result so far: 28463.09
Subtract 7335 from 8100 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 11:
815 goes into 7650 9 times with a remainder of 315.
Use 9 as the next digit of our solution. 
Result so far: 28463.099
The remainder is 315 after subtracting 7335 from 7650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 28463.099, and the remainder is 0.0315.
