We divide 18851372 by 321
The aim is to understand the frequency of 321 in 18851372.

Moving on to step 1:
The number 321 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 321

Going ahead to step 2:
The number 321 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 321

Going ahead to step 3:
If we divide 188 by 321, we get 0 and a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 188 leaves us with 188.
Bring next digit (5) of the dividend behind the 188 and repeat the process: 1885 / 321

Step 4:
The number 321 fits into 1885 5 times, leaving a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1605 from 1885 and we're left with 280.
Bring next digit (1) of the dividend behind the 280 and repeat the process: 2801 / 321

Moving on to step 5:
When dividing 2801 by 321, we get 8 with a remainder of 233.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 2568 from 2801 to get 233.
Take the next digit (3) from the dividend and append it to 233, then repeat: 2333 / 321

Going ahead to step 6:
The number 321 fits into 2333 7 times, leaving a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 587.0
Deduct 2247 from 2333 and we're left with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 321

On to step 7:
321 can be fit into 867 2 times, resulting in a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 5872.0
If we subtract 642 from 867, we get 225.
Fetch the next digit (2) from the dividend, attach it to 225 and continue: 2252 / 321

Going ahead to step 8:
321 goes into 2252 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 58727.0
The remainder is 5 after subtracting 2247 from 2252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
When dividing 50 by 321, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 58727.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 321, we get 1 and a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 58727.01
Subtract 321 from 500 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 11:
321 goes into 1790 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 58727.015
Subtract 1605 from 1790 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
When dividing 1850 by 321, we get 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 58727.0155
The remainder is 245 after subtracting 1605 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

After the division, we end up with 58727.0155 and a remainder of 0.00245.
