28021714 ÷ 380 
The aim is to understand the frequency of 380 in 28021714.

Let's proceed to step 1:
380 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 380

Going ahead to step 2:
If we divide 28 by 380, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 380

Moving on to step 3:
380 can be fit into 280 0 times, resulting in a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 280 to get 280.
Bring next digit (2) of the dividend behind the 280 and repeat the process: 2802 / 380

Moving on to step 4:
380 goes into 2802 7 times with a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 2660 from 2802 leaves us with 142.
Fetch the next digit (1) from the dividend, attach it to 142 and continue: 1421 / 380

Step 5:
The number 380 fits into 1421 3 times, leaving a remainder of 281.
Use 3 as the next digit of our solution. 
Result so far: 73.0
The remainder is 281 after subtracting 1140 from 1421.
Bring next digit (7) of the dividend behind the 281 and repeat the process: 2817 / 380

Moving on to step 6:
380 can be fit into 2817 7 times, resulting in a remainder of 157.
Put 7 as the next digit of the answer. 
Result so far: 737.0
If we take 2660 away from 2817, we end up with 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 380

Let's proceed to step 7:
380 can be fit into 1571 4 times, resulting in a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 7374.0
Subtract 1520 from 1571 to get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 380

Advancing to step 8:
If we divide 514 by 380, we get 1 and a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 73741.0
Subtracting 380 from 514 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
380 can be fit into 1340 3 times, resulting in a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 73741.3
Subtracting 1140 from 1340 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
380 can be fit into 2000 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 73741.35
If we subtract 1900 from 2000, 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.

Let's proceed to step 11:
When dividing 1000 by 380, we get 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 73741.352
Subtracting 760 from 1000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
2400 divided by 380 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 73741.3526
Subtract 2280 from 2400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
1200 divided by 380 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 73741.35263
Deduct 1140 from 1200 and we're left with 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 14:
When dividing 600 by 380, we get 1 with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 73741.352631
Deduct 380 from 600 and we're left 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.

Moving on to step 15:
When dividing 2200 by 380, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 73741.3526315
Deduct 1900 from 2200 and we're left 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.

Step 16:
The number 380 fits into 3000 7 times, leaving a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 73741.35263157
Subtract 2660 from 3000 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 73741.35263157, with a leftover of 3.4e-07.
