We're dividing 49968980 by 172 
The aim is to understand the frequency of 172 in 49968980.

Let's proceed to step 1:
4 divided by 172 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 172

On to step 2:
When dividing 49 by 172, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 172

On to step 3:
499 divided by 172 is 2 with a remainder of 155.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 344 from 499 leaves us with 155.
Append the next digit (6) from the dividend to 155 and continue with: 1556 / 172

On to step 4:
172 can be fit into 1556 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 29.0
If we take 1548 away from 1556, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 172

Moving on to step 5:
88 divided by 172 is 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 290.0
Deduct 0 from 88 and we're left with 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 172

Moving on to step 6:
172 can be fit into 889 5 times, resulting in a remainder of 29.
The next digit of our result is 5. 
Result so far: 2905.0
If we take 860 away from 889, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 172

Going ahead to step 7:
172 can be fit into 298 1 times, resulting in a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 29051.0
Subtracting 172 from 298 leaves us with 126.
Fetch the next digit (0) from the dividend, attach it to 126 and continue: 1260 / 172

Advancing to step 8:
172 goes into 1260 7 times with a remainder of 56.
The next digit of our result is 7. 
Result so far: 290517.0
If we subtract 1204 from 1260, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
172 goes into 560 3 times with a remainder of 44.
The next digit of our result is 3. 
Result so far: 290517.3
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
When dividing 440 by 172, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 290517.32
The remainder is 96 after subtracting 344 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
960 divided by 172 is 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 290517.325
If we subtract 860 from 960, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
The number 172 fits into 1000 5 times, leaving a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 290517.3255
The remainder is 140 after subtracting 860 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 290517.3255, and the remainder is 0.0014.
