39633729 ÷ 555 
The aim is to understand the frequency of 555 in 39633729.

Going ahead to step 1:
If we divide 3 by 555, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 555

Going ahead to step 2:
555 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 555

Let's proceed to step 3:
When dividing 396 by 555, we get 0 with a remainder of 396.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 396 to get 396.
Include the next digit (3) from the dividend after 396, then repeat: 3963 / 555

Step 4:
555 can be fit into 3963 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 3885 from 3963 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 555

Let's proceed to step 5:
783 divided by 555 is 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtract 555 from 783 to get 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 555

Moving on to step 6:
2287 divided by 555 is 4 with a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
If we subtract 2220 from 2287, we get 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 555

Going ahead to step 7:
555 can be fit into 672 1 times, resulting in a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 7141.0
If we take 555 away from 672, we end up with 117.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 555

Moving on to step 8:
555 can be fit into 1179 2 times, resulting in a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 71412.0
The remainder is 69 after subtracting 1110 from 1179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
555 goes into 690 1 times with a remainder of 135.
The next digit of our result is 1. 
Result so far: 71412.1
The remainder is 135 after subtracting 555 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
555 can be fit into 1350 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 71412.12
Subtracting 1110 from 1350 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
When dividing 2400 by 555, we get 4 with a remainder of 180.
The next digit of our result is 4. 
Result so far: 71412.124
Deduct 2220 from 2400 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 12:
555 goes into 1800 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 71412.1243
Subtract 1665 from 1800 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 13:
If we divide 1350 by 555, we get 2 and a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 71412.12432
If we subtract 1110 from 1350, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
When dividing 2400 by 555, we get 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 71412.124324
If we subtract 2220 from 2400, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
If we divide 1800 by 555, we get 3 and a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 71412.1243243
If we take 1665 away from 1800, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 16:
555 goes into 1350 2 times with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 71412.12432432
If we subtract 1110 from 1350, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 71412.12432432 and a remainder of 2.4e-07.
