18784598 divided by 806 
The aim is to understand the frequency of 806 in 18784598.

Step 1:
The number 806 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 806

Going ahead to step 2:
If we divide 18 by 806, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 806

Moving on to step 3:
If we divide 187 by 806, we get 0 and a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 187, we get 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 806

Going ahead to step 4:
If we divide 1878 by 806, we get 2 and a remainder of 266.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1612 from 1878 leaves us with 266.
Include the next digit (4) from the dividend after 266, then repeat: 2664 / 806

Moving on to step 5:
The number 806 fits into 2664 3 times, leaving a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 2418 away from 2664, we end up with 246.
Append the next digit (5) from the dividend to 246 and continue with: 2465 / 806

Going ahead to step 6:
2465 divided by 806 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Deduct 2418 from 2465 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 806

Let's proceed to step 7:
When dividing 479 by 806, we get 0 with a remainder of 479.
The next digit of our result is 0. 
Result so far: 2330.0
Deduct 0 from 479 and we're left with 479.
Fetch the next digit (8) from the dividend, attach it to 479 and continue: 4798 / 806

On to step 8:
If we divide 4798 by 806, we get 5 and a remainder of 768.
Record the quotient 5 as the next digit in the result. 
Result so far: 23305.0
If we take 4030 away from 4798, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 9:
7680 divided by 806 is 9 with a remainder of 426.
Put 9 as the next digit of the answer. 
Result so far: 23305.9
The remainder is 426 after subtracting 7254 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 10:
4260 divided by 806 is 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 23305.95
The remainder is 230 after subtracting 4030 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
2300 divided by 806 is 2 with a remainder of 688.
Write down 2 as next digit of the result. 
Result so far: 23305.952
Subtract 1612 from 2300 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 12:
6880 divided by 806 is 8 with a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 23305.9528
Subtracting 6448 from 6880 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 13:
When dividing 4320 by 806, we get 5 with a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 23305.95285
If we take 4030 away from 4320, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
If we divide 2900 by 806, we get 3 and a remainder of 482.
The number 3 becomes the next digit in our result. 
Result so far: 23305.952853
Subtracting 2418 from 2900 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 15:
When dividing 4820 by 806, we get 5 with a remainder of 790.
Write down 5 as next digit of the result. 
Result so far: 23305.9528535
Subtract 4030 from 4820 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 16:
806 can be fit into 7900 9 times, resulting in a remainder of 646.
The next digit of our result is 9. 
Result so far: 23305.95285359
Subtracting 7254 from 7900 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

The final outcome is 23305.95285359, with a leftover of 6.46e-07.
