We look at the division of 51458988 by 554 
The aim is to understand the frequency of 554 in 51458988.

Let's proceed to step 1:
When dividing 5 by 554, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 554

Advancing to step 2:
The number 554 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 554

Moving on to step 3:
514 divided by 554 is 0 with a remainder of 514.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 514 leaves us with 514.
Grab the next digit (5) from the dividend, add it to 514, then carry on: 5145 / 554

Moving on to step 4:
554 goes into 5145 9 times with a remainder of 159.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 4986 from 5145 and we're left with 159.
Grab the next digit (8) from the dividend, add it to 159, then carry on: 1598 / 554

Moving on to step 5:
554 goes into 1598 2 times with a remainder of 490.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 490 after subtracting 1108 from 1598.
Include the next digit (9) from the dividend after 490, then repeat: 4909 / 554

Step 6:
The number 554 fits into 4909 8 times, leaving a remainder of 477.
Record the quotient 8 as the next digit in the result. 
Result so far: 928.0
Deduct 4432 from 4909 and we're left with 477.
Include the next digit (8) from the dividend after 477, then repeat: 4778 / 554

Advancing to step 7:
554 goes into 4778 8 times with a remainder of 346.
The next digit of our result is 8. 
Result so far: 9288.0
The remainder is 346 after subtracting 4432 from 4778.
Append the next digit (8) from the dividend to 346 and continue with: 3468 / 554

Let's proceed to step 8:
When dividing 3468 by 554, we get 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 92886.0
If we take 3324 away from 3468, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
554 goes into 1440 2 times with a remainder of 332.
Record the quotient 2 as the next digit in the result. 
Result so far: 92886.2
Deduct 1108 from 1440 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
If we divide 3320 by 554, we get 5 and a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 92886.25
If we take 2770 away from 3320, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
554 can be fit into 5500 9 times, resulting in a remainder of 514.
Write down 9 as next digit of the result. 
Result so far: 92886.259
Subtracting 4986 from 5500 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 12:
If we divide 5140 by 554, we get 9 and a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 92886.2599
Subtract 4986 from 5140 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 92886.2599 with a remainder of 0.00154.
