Let's divide 43903720 by 555
The aim is to understand the frequency of 555 in 43903720.

Moving on to step 1:
555 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 555

Step 2:
When dividing 43 by 555, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 555

Advancing to step 3:
The number 555 fits into 439 0 times, leaving a remainder of 439.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 439, we end up with 439.
Bring next digit (0) of the dividend behind the 439 and repeat the process: 4390 / 555

Going ahead to step 4:
If we divide 4390 by 555, we get 7 and a remainder of 505.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 505 after subtracting 3885 from 4390.
Fetch the next digit (3) from the dividend, attach it to 505 and continue: 5053 / 555

Let's proceed to step 5:
If we divide 5053 by 555, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 4995 from 5053 to get 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 555

Going ahead to step 6:
The number 555 fits into 587 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 791.0
If we subtract 555 from 587, we get 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 555

Advancing to step 7:
555 goes into 322 0 times with a remainder of 322.
The next digit of our result is 0. 
Result so far: 7910.0
If we take 0 away from 322, we end up with 322.
Append the next digit (0) from the dividend to 322 and continue with: 3220 / 555

Let's proceed to step 8:
If we divide 3220 by 555, we get 5 and a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 79105.0
The remainder is 445 after subtracting 2775 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 9:
4450 divided by 555 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 79105.8
Deduct 4440 from 4450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 555, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 79105.8
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
555 can be fit into 1000 1 times, resulting in a remainder of 445.
Put 1 as the next digit of the answer. 
Result so far: 79105.801
Subtracting 555 from 1000 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 12:
4450 divided by 555 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 79105.8018
Deduct 4440 from 4450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
100 divided by 555 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 79105.8018
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
555 goes into 1000 1 times with a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 79105.801801
Deduct 555 from 1000 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 15:
555 goes into 4450 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 79105.8018018
If we take 4440 away from 4450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
The number 555 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 79105.8018018
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 79105.8018018 and a remainder of 1e-07.
