We look at the division of 75549041 by 380 
The aim is to understand the frequency of 380 in 75549041.

Advancing to step 1:
When dividing 7 by 380, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 380

Step 2:
The number 380 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 380

Advancing to step 3:
When dividing 755 by 380, we get 1 with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 380 from 755 to get 375.
Include the next digit (4) from the dividend after 375, then repeat: 3754 / 380

Going ahead to step 4:
If we divide 3754 by 380, we get 9 and a remainder of 334.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 3420 away from 3754, we end up with 334.
Take the next digit (9) from the dividend and append it to 334, then repeat: 3349 / 380

Advancing to step 5:
The number 380 fits into 3349 8 times, leaving a remainder of 309.
Write down 8 as next digit of the result. 
Result so far: 198.0
Subtract 3040 from 3349 to get 309.
Append the next digit (0) from the dividend to 309 and continue with: 3090 / 380

Going ahead to step 6:
When dividing 3090 by 380, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
Subtracting 3040 from 3090 leaves us with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 380

Step 7:
When dividing 504 by 380, we get 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 19881.0
Subtract 380 from 504 to get 124.
Include the next digit (1) from the dividend after 124, then repeat: 1241 / 380

Step 8:
380 can be fit into 1241 3 times, resulting in a remainder of 101.
The next digit of our result is 3. 
Result so far: 198813.0
The remainder is 101 after subtracting 1140 from 1241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
1010 divided by 380 is 2 with a remainder of 250.
Use 2 as the next digit of our solution. 
Result so far: 198813.2
If we take 760 away from 1010, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
380 goes into 2500 6 times with a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 198813.26
If we take 2280 away from 2500, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
If we divide 2200 by 380, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 198813.265
Subtracting 1900 from 2200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
The number 380 fits into 3000 7 times, leaving a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 198813.2657
The remainder is 340 after subtracting 2660 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 13:
380 can be fit into 3400 8 times, resulting in a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 198813.26578
The remainder is 360 after subtracting 3040 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
When dividing 3600 by 380, we get 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 198813.265789
If we take 3420 away from 3600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
When dividing 1800 by 380, we get 4 with a remainder of 280.
The next digit of our result is 4. 
Result so far: 198813.2657894
If we subtract 1520 from 1800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
2800 divided by 380 is 7 with a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 198813.26578947
If we take 2660 away from 2800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 198813.26578947, with a leftover of 1.4e-07.
