We're dividing 16369941 by 554 
The aim is to understand the frequency of 554 in 16369941.

On to step 1:
1 divided by 554 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 554

On to step 2:
554 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 554

On to step 3:
554 can be fit into 163 0 times, resulting in a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 163, we get 163.
Take the next digit (6) from the dividend and append it to 163, then repeat: 1636 / 554

Going ahead to step 4:
The number 554 fits into 1636 2 times, leaving a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1108 away from 1636, we end up with 528.
Fetch the next digit (9) from the dividend, attach it to 528 and continue: 5289 / 554

Moving on to step 5:
The number 554 fits into 5289 9 times, leaving a remainder of 303.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 4986 from 5289 leaves us with 303.
Grab the next digit (9) from the dividend, add it to 303, then carry on: 3039 / 554

Going ahead to step 6:
554 goes into 3039 5 times with a remainder of 269.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
The remainder is 269 after subtracting 2770 from 3039.
Include the next digit (4) from the dividend after 269, then repeat: 2694 / 554

Step 7:
When dividing 2694 by 554, we get 4 with a remainder of 478.
The next digit of our result is 4. 
Result so far: 2954.0
Subtract 2216 from 2694 to get 478.
Take the next digit (1) from the dividend and append it to 478, then repeat: 4781 / 554

Let's proceed to step 8:
554 can be fit into 4781 8 times, resulting in a remainder of 349.
Put 8 as the next digit of the answer. 
Result so far: 29548.0
The remainder is 349 after subtracting 4432 from 4781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 9:
The number 554 fits into 3490 6 times, leaving a remainder of 166.
Put 6 as the next digit of the answer. 
Result so far: 29548.6
If we subtract 3324 from 3490, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 10:
If we divide 1660 by 554, we get 2 and a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 29548.62
If we subtract 1108 from 1660, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 11:
5520 divided by 554 is 9 with a remainder of 534.
Put 9 as the next digit of the answer. 
Result so far: 29548.629
Subtract 4986 from 5520 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 12:
When dividing 5340 by 554, we get 9 with a remainder of 354.
Write down 9 as next digit of the result. 
Result so far: 29548.6299
Subtracting 4986 from 5340 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final outcome is 29548.6299, with a leftover of 0.00354.
