55438129 ÷ 189 
The aim is to understand the frequency of 189 in 55438129.

Let's proceed to step 1:
189 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 189

Step 2:
The number 189 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 189

Going ahead to step 3:
When dividing 554 by 189, we get 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 2.0
If we take 378 away from 554, we end up with 176.
Bring next digit (3) of the dividend behind the 176 and repeat the process: 1763 / 189

Advancing to step 4:
If we divide 1763 by 189, we get 9 and a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 1701 from 1763 leaves us with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 189

On to step 5:
The number 189 fits into 628 3 times, leaving a remainder of 61.
The next digit of our result is 3. 
Result so far: 293.0
Subtracting 567 from 628 leaves us with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 189

Going ahead to step 6:
189 goes into 611 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 2933.0
Deduct 567 from 611 and we're left with 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 189

Let's proceed to step 7:
The number 189 fits into 442 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 29332.0
If we take 378 away from 442, we end up with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 189

Step 8:
When dividing 649 by 189, we get 3 with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 293323.0
If we subtract 567 from 649, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
189 can be fit into 820 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 293323.4
Deduct 756 from 820 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
640 divided by 189 is 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 293323.43
Deduct 567 from 640 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
189 can be fit into 730 3 times, resulting in a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 293323.433
Subtracting 567 from 730 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Our division results in 293323.433 with a remaining 0.0163.
