Let's divide 40640904 by 555
The aim is to understand the frequency of 555 in 40640904.

Let's proceed to step 1:
4 divided by 555 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 555

Advancing to step 2:
555 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 555

Going ahead to step 3:
When dividing 406 by 555, we get 0 with a remainder of 406.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 406 after subtracting 0 from 406.
Take the next digit (4) from the dividend and append it to 406, then repeat: 4064 / 555

Going ahead to step 4:
If we divide 4064 by 555, we get 7 and a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 3885 from 4064 leaves us with 179.
Include the next digit (0) from the dividend after 179, then repeat: 1790 / 555

Advancing to step 5:
If we divide 1790 by 555, we get 3 and a remainder of 125.
The next digit of our result is 3. 
Result so far: 73.0
Subtracting 1665 from 1790 leaves us with 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 555

Advancing to step 6:
555 can be fit into 1259 2 times, resulting in a remainder of 149.
Put 2 as the next digit of the answer. 
Result so far: 732.0
The remainder is 149 after subtracting 1110 from 1259.
Bring next digit (0) of the dividend behind the 149 and repeat the process: 1490 / 555

On to step 7:
The number 555 fits into 1490 2 times, leaving a remainder of 380.
The next digit of our result is 2. 
Result so far: 7322.0
Subtract 1110 from 1490 to get 380.
Take the next digit (4) from the dividend and append it to 380, then repeat: 3804 / 555

Going ahead to step 8:
555 can be fit into 3804 6 times, resulting in a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 73226.0
Subtracting 3330 from 3804 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
The number 555 fits into 4740 8 times, leaving a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 73226.8
Subtract 4440 from 4740 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
When dividing 3000 by 555, we get 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 73226.85
If we take 2775 away from 3000, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
2250 divided by 555 is 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 73226.854
Deduct 2220 from 2250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 555, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 73226.854
Deduct 0 from 300 and we're left 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.

Going ahead to step 13:
If we divide 3000 by 555, we get 5 and a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 73226.85405
The remainder is 225 after subtracting 2775 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 14:
If we divide 2250 by 555, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 73226.854054
Subtracting 2220 from 2250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
When dividing 300 by 555, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 73226.854054
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
If we divide 3000 by 555, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 73226.85405405
Subtract 2775 from 3000 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Our division results in 73226.85405405 with a remaining 2.25e-07.
