96906369 ÷ 555 
The aim is to understand the frequency of 555 in 96906369.

Let's proceed to step 1:
555 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 555

Going ahead to step 2:
When dividing 96 by 555, we get 0 with a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Append the next digit (9) from the dividend to 96 and continue with: 969 / 555

Step 3:
555 can be fit into 969 1 times, resulting in a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 555 from 969, we get 414.
Include the next digit (0) from the dividend after 414, then repeat: 4140 / 555

Step 4:
When dividing 4140 by 555, we get 7 with a remainder of 255.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 3885 from 4140 leaves us with 255.
Fetch the next digit (6) from the dividend, attach it to 255 and continue: 2556 / 555

On to step 5:
When dividing 2556 by 555, we get 4 with a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 174.0
If we take 2220 away from 2556, we end up with 336.
Grab the next digit (3) from the dividend, add it to 336, then carry on: 3363 / 555

On to step 6:
3363 divided by 555 is 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 1746.0
Deduct 3330 from 3363 and we're left with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 555

Advancing to step 7:
The number 555 fits into 336 0 times, leaving a remainder of 336.
The next digit of our result is 0. 
Result so far: 17460.0
Subtracting 0 from 336 leaves us with 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 555

On to step 8:
When dividing 3369 by 555, we get 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 174606.0
Deduct 3330 from 3369 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
If we divide 390 by 555, we get 0 and a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 174606.0
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
The number 555 fits into 3900 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 174606.07
Deduct 3885 from 3900 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 555 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 174606.07
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
When dividing 1500 by 555, we get 2 with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 174606.0702
Subtracting 1110 from 1500 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
When dividing 3900 by 555, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 174606.07027
The remainder is 15 after subtracting 3885 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
555 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 174606.07027
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
555 can be fit into 1500 2 times, resulting in a remainder of 390.
Put 2 as the next digit of the answer. 
Result so far: 174606.0702702
If we subtract 1110 from 1500, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 16:
When dividing 3900 by 555, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 174606.07027027
The remainder is 15 after subtracting 3885 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 174606.07027027, with a leftover of 1.5e-08.
