We look at the division of 67490331 by 445 
The aim is to understand the frequency of 445 in 67490331.

Going ahead to step 1:
When dividing 6 by 445, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 445

On to step 2:
When dividing 67 by 445, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 445

Going ahead to step 3:
When dividing 674 by 445, we get 1 with a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 445 away from 674, we end up with 229.
Fetch the next digit (9) from the dividend, attach it to 229 and continue: 2299 / 445

Let's proceed to step 4:
The number 445 fits into 2299 5 times, leaving a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2225 from 2299, we get 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 445

On to step 5:
When dividing 740 by 445, we get 1 with a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 295 after subtracting 445 from 740.
Take the next digit (3) from the dividend and append it to 295, then repeat: 2953 / 445

Let's proceed to step 6:
2953 divided by 445 is 6 with a remainder of 283.
The next digit of our result is 6. 
Result so far: 1516.0
If we take 2670 away from 2953, we end up with 283.
Take the next digit (3) from the dividend and append it to 283, then repeat: 2833 / 445

Moving on to step 7:
If we divide 2833 by 445, we get 6 and a remainder of 163.
Record the quotient 6 as the next digit in the result. 
Result so far: 15166.0
Subtracting 2670 from 2833 leaves us with 163.
Take the next digit (1) from the dividend and append it to 163, then repeat: 1631 / 445

On to step 8:
445 can be fit into 1631 3 times, resulting in a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 151663.0
If we take 1335 away from 1631, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
445 goes into 2960 6 times with a remainder of 290.
Put 6 as the next digit of the answer. 
Result so far: 151663.6
If we take 2670 away from 2960, 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.

Step 10:
When dividing 2900 by 445, we get 6 with a remainder of 230.
The number 6 becomes the next digit in our result. 
Result so far: 151663.66
Deduct 2670 from 2900 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The quotient of the division is 151663.66, and the remainder is 0.23.
