57019816 ÷ 380 
The aim is to understand the frequency of 380 in 57019816.

Advancing to step 1:
When dividing 5 by 380, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 380

Step 2:
When dividing 57 by 380, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 380

Going ahead to step 3:
380 goes into 570 1 times with a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 380 from 570 and we're left with 190.
Fetch the next digit (1) from the dividend, attach it to 190 and continue: 1901 / 380

Step 4:
The number 380 fits into 1901 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1900 away from 1901, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 380

Advancing to step 5:
If we divide 19 by 380, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 19 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 380

Let's proceed to step 6:
The number 380 fits into 198 0 times, leaving a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 1500.0
The remainder is 198 after subtracting 0 from 198.
Take the next digit (1) from the dividend and append it to 198, then repeat: 1981 / 380

Moving on to step 7:
1981 divided by 380 is 5 with a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 15005.0
If we take 1900 away from 1981, we end up with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 380

Let's proceed to step 8:
380 can be fit into 816 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 150052.0
If we take 760 away from 816, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 380, we get 1 and a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 150052.1
If we subtract 380 from 560, we 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.

Going ahead to step 10:
If we divide 1800 by 380, we get 4 and a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 150052.14
Subtracting 1520 from 1800 leaves us 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.

Let's proceed to step 11:
380 can be fit into 2800 7 times, resulting in a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 150052.147
Subtracting 2660 from 2800 leaves us 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.

Moving on to step 12:
If we divide 1400 by 380, we get 3 and a remainder of 260.
Record the quotient 3 as the next digit in the result. 
Result so far: 150052.1473
If we take 1140 away from 1400, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
If we divide 2600 by 380, we get 6 and a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 150052.14736
If we subtract 2280 from 2600, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
3200 divided by 380 is 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 150052.147368
Subtract 3040 from 3200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
380 can be fit into 1600 4 times, resulting in a remainder of 80.
The next digit of our result is 4. 
Result so far: 150052.1473684
Subtract 1520 from 1600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
380 can be fit into 800 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 150052.14736842
Subtract 760 from 800 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 150052.14736842, and the remainder is 4e-08.
