We're dividing 34399088 by 380 
The aim is to understand the frequency of 380 in 34399088.

Let's proceed to step 1:
The number 380 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 380

Going ahead to step 2:
The number 380 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 380

Advancing to step 3:
380 can be fit into 343 0 times, resulting in a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 343, we end up with 343.
Bring next digit (9) of the dividend behind the 343 and repeat the process: 3439 / 380

Moving on to step 4:
The number 380 fits into 3439 9 times, leaving a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3420 away from 3439, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 380

Going ahead to step 5:
The number 380 fits into 199 0 times, leaving a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 199, we end up with 199.
Fetch the next digit (0) from the dividend, attach it to 199 and continue: 1990 / 380

Going ahead to step 6:
When dividing 1990 by 380, we get 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 905.0
Subtracting 1900 from 1990 leaves us with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 380

Advancing to step 7:
908 divided by 380 is 2 with a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 9052.0
If we take 760 away from 908, we end up with 148.
Take the next digit (8) from the dividend and append it to 148, then repeat: 1488 / 380

Going ahead to step 8:
380 can be fit into 1488 3 times, resulting in a remainder of 348.
Record the quotient 3 as the next digit in the result. 
Result so far: 90523.0
Subtracting 1140 from 1488 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
If we divide 3480 by 380, we get 9 and a remainder of 60.
The next digit of our result is 9. 
Result so far: 90523.9
Subtract 3420 from 3480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
380 can be fit into 600 1 times, resulting in a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 90523.91
If we subtract 380 from 600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
2200 divided by 380 is 5 with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 90523.915
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.

Let's proceed to step 12:
When dividing 3000 by 380, we get 7 with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 90523.9157
Deduct 2660 from 3000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 13:
3400 divided by 380 is 8 with a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 90523.91578
Deduct 3040 from 3400 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
3600 divided by 380 is 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 90523.915789
Subtract 3420 from 3600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
When dividing 1800 by 380, we get 4 with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 90523.9157894
If we take 1520 away from 1800, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
If we divide 2800 by 380, we get 7 and a remainder of 140.
The next digit of our result is 7. 
Result so far: 90523.91578947
If we subtract 2660 from 2800, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 90523.91578947 with a balance of 1.4e-07.
