21923298 divided by 380 
The aim is to understand the frequency of 380 in 21923298.

Step 1:
If we divide 2 by 380, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 380

On to step 2:
380 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 380

Let's proceed to step 3:
The number 380 fits into 219 0 times, leaving a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Include the next digit (2) from the dividend after 219, then repeat: 2192 / 380

Let's proceed to step 4:
380 can be fit into 2192 5 times, resulting in a remainder of 292.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 292 after subtracting 1900 from 2192.
Include the next digit (3) from the dividend after 292, then repeat: 2923 / 380

Moving on to step 5:
2923 divided by 380 is 7 with a remainder of 263.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 2660 from 2923 leaves us with 263.
Fetch the next digit (2) from the dividend, attach it to 263 and continue: 2632 / 380

Advancing to step 6:
The number 380 fits into 2632 6 times, leaving a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 576.0
If we take 2280 away from 2632, we end up with 352.
Fetch the next digit (9) from the dividend, attach it to 352 and continue: 3529 / 380

Advancing to step 7:
380 can be fit into 3529 9 times, resulting in a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 5769.0
Subtract 3420 from 3529 to get 109.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 380

Moving on to step 8:
The number 380 fits into 1098 2 times, leaving a remainder of 338.
The next digit of our result is 2. 
Result so far: 57692.0
Subtract 760 from 1098 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
When dividing 3380 by 380, we get 8 with a remainder of 340.
The number 8 becomes the next digit in our result. 
Result so far: 57692.8
If we subtract 3040 from 3380, we 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.

Step 10:
380 can be fit into 3400 8 times, resulting in a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 57692.88
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.

The final result is 57692.88 with a remainder of 0.36.
