We look at the division of 21384006 by 230 
The aim is to understand the frequency of 230 in 21384006.

Going ahead to step 1:
230 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 (1) from the dividend, attach it to 2 and continue: 21 / 230

Going ahead to step 2:
The number 230 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 230

Advancing to step 3:
If we divide 213 by 230, we get 0 and a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Append the next digit (8) from the dividend to 213 and continue with: 2138 / 230

Step 4:
When dividing 2138 by 230, we get 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 2070 from 2138 leaves us with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 230

Advancing to step 5:
The number 230 fits into 684 2 times, leaving a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtracting 460 from 684 leaves us with 224.
Grab the next digit (0) from the dividend, add it to 224, then carry on: 2240 / 230

Advancing to step 6:
2240 divided by 230 is 9 with a remainder of 170.
The number 9 becomes the next digit in our result. 
Result so far: 929.0
Subtract 2070 from 2240 to get 170.
Fetch the next digit (0) from the dividend, attach it to 170 and continue: 1700 / 230

Going ahead to step 7:
If we divide 1700 by 230, we get 7 and a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 9297.0
If we subtract 1610 from 1700, we get 90.
Fetch the next digit (6) from the dividend, attach it to 90 and continue: 906 / 230

On to step 8:
230 goes into 906 3 times with a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 92973.0
Deduct 690 from 906 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 9:
The number 230 fits into 2160 9 times, leaving a remainder of 90.
The next digit of our result is 9. 
Result so far: 92973.9
The remainder is 90 after subtracting 2070 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 230 is 3 with a remainder of 210.
Put 3 as the next digit of the answer. 
Result so far: 92973.93
Subtract 690 from 900 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
The number 230 fits into 2100 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 92973.939
If we take 2070 away from 2100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
230 goes into 300 1 times with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 92973.9391
Deduct 230 from 300 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
230 goes into 700 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 92973.93913
Subtracting 690 from 700 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 230, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 92973.93913
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
The number 230 fits into 1000 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 92973.9391304
If we take 920 away from 1000, we end up with 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:
The number 230 fits into 800 3 times, leaving a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 92973.93913043
If we take 690 away from 800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 92973.93913043 and a remainder of 1.1e-07.
