We're dividing 18997184 by 321 
The aim is to understand the frequency of 321 in 18997184.

Moving on to step 1:
When dividing 1 by 321, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 321

On to step 2:
321 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 321

Moving on to step 3:
189 divided by 321 is 0 with a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 189, we end up with 189.
Fetch the next digit (9) from the dividend, attach it to 189 and continue: 1899 / 321

Step 4:
321 goes into 1899 5 times with a remainder of 294.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 1605 from 1899, we get 294.
Append the next digit (7) from the dividend to 294 and continue with: 2947 / 321

Advancing to step 5:
321 goes into 2947 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 2889 from 2947 leaves us with 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 321

Advancing to step 6:
If we divide 581 by 321, we get 1 and a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 591.0
The remainder is 260 after subtracting 321 from 581.
Bring next digit (8) of the dividend behind the 260 and repeat the process: 2608 / 321

Step 7:
If we divide 2608 by 321, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 5918.0
Deduct 2568 from 2608 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 321

Going ahead to step 8:
If we divide 404 by 321, we get 1 and a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 59181.0
If we subtract 321 from 404, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
When dividing 830 by 321, we get 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 59181.2
Deduct 642 from 830 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
321 can be fit into 1880 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 59181.25
If we subtract 1605 from 1880, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
The number 321 fits into 2750 8 times, leaving a remainder of 182.
Put 8 as the next digit of the answer. 
Result so far: 59181.258
Subtracting 2568 from 2750 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 12:
The number 321 fits into 1820 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 59181.2585
Subtract 1605 from 1820 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
When dividing 2150 by 321, we get 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 59181.25856
Subtract 1926 from 2150 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
321 goes into 2240 6 times with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 59181.258566
If we subtract 1926 from 2240, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

In conclusion, the division gives 59181.258566 with a balance of 3.14e-05.
