We're dividing 23919156 by 806 
The aim is to understand the frequency of 806 in 23919156.

Let's proceed to step 1:
2 divided by 806 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 806

Moving on to step 2:
When dividing 23 by 806, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 806

On to step 3:
239 divided by 806 is 0 with a remainder of 239.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 239 after subtracting 0 from 239.
Include the next digit (1) from the dividend after 239, then repeat: 2391 / 806

Step 4:
When dividing 2391 by 806, we get 2 with a remainder of 779.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1612 from 2391 leaves us with 779.
Bring next digit (9) of the dividend behind the 779 and repeat the process: 7799 / 806

Advancing to step 5:
The number 806 fits into 7799 9 times, leaving a remainder of 545.
The next digit of our result is 9. 
Result so far: 29.0
If we take 7254 away from 7799, we end up with 545.
Append the next digit (1) from the dividend to 545 and continue with: 5451 / 806

Going ahead to step 6:
5451 divided by 806 is 6 with a remainder of 615.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Deduct 4836 from 5451 and we're left with 615.
Grab the next digit (5) from the dividend, add it to 615, then carry on: 6155 / 806

Let's proceed to step 7:
6155 divided by 806 is 7 with a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 2967.0
If we take 5642 away from 6155, we end up with 513.
Take the next digit (6) from the dividend and append it to 513, then repeat: 5136 / 806

Let's proceed to step 8:
806 can be fit into 5136 6 times, resulting in a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 29676.0
Subtracting 4836 from 5136 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 9:
If we divide 3000 by 806, we get 3 and a remainder of 582.
The next digit of our result is 3. 
Result so far: 29676.3
The remainder is 582 after subtracting 2418 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 10:
The number 806 fits into 5820 7 times, leaving a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 29676.37
Subtracting 5642 from 5820 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 11:
The number 806 fits into 1780 2 times, leaving a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 29676.372
If we take 1612 away from 1780, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
806 can be fit into 1680 2 times, resulting in a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 29676.3722
The remainder is 68 after subtracting 1612 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 29676.3722 with a remainder of 0.00068.
