18058192 divided by 606 
The aim is to understand the frequency of 606 in 18058192.

Going ahead to step 1:
If we divide 1 by 606, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 606

On to step 2:
18 divided by 606 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 606

Step 3:
606 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 180 to get 180.
Grab the next digit (5) from the dividend, add it to 180, then carry on: 1805 / 606

Going ahead to step 4:
The number 606 fits into 1805 2 times, leaving a remainder of 593.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1212 from 1805, we get 593.
Bring next digit (8) of the dividend behind the 593 and repeat the process: 5938 / 606

Moving on to step 5:
606 can be fit into 5938 9 times, resulting in a remainder of 484.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 484 after subtracting 5454 from 5938.
Take the next digit (1) from the dividend and append it to 484, then repeat: 4841 / 606

Moving on to step 6:
606 goes into 4841 7 times with a remainder of 599.
The next digit of our result is 7. 
Result so far: 297.0
Deduct 4242 from 4841 and we're left with 599.
Include the next digit (9) from the dividend after 599, then repeat: 5999 / 606

Moving on to step 7:
The number 606 fits into 5999 9 times, leaving a remainder of 545.
Put 9 as the next digit of the answer. 
Result so far: 2979.0
Subtracting 5454 from 5999 leaves us with 545.
Take the next digit (2) from the dividend and append it to 545, then repeat: 5452 / 606

Step 8:
5452 divided by 606 is 8 with a remainder of 604.
The next digit of our result is 8. 
Result so far: 29798.0
If we subtract 4848 from 5452, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 9:
When dividing 6040 by 606, we get 9 with a remainder of 586.
Use 9 as the next digit of our solution. 
Result so far: 29798.9
The remainder is 586 after subtracting 5454 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 10:
606 goes into 5860 9 times with a remainder of 406.
Record the quotient 9 as the next digit in the result. 
Result so far: 29798.99
Subtract 5454 from 5860 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final outcome is 29798.99, with a leftover of 0.406.
