We look at the division of 18301173 by 393 
The aim is to understand the frequency of 393 in 18301173.

Moving on to step 1:
If we divide 1 by 393, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 393

Let's proceed to step 2:
The number 393 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 393

Moving on to step 3:
When dividing 183 by 393, we get 0 with a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Grab the next digit (0) from the dividend, add it to 183, then carry on: 1830 / 393

Going ahead to step 4:
393 can be fit into 1830 4 times, resulting in a remainder of 258.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1572 from 1830, we get 258.
Bring next digit (1) of the dividend behind the 258 and repeat the process: 2581 / 393

Going ahead to step 5:
If we divide 2581 by 393, we get 6 and a remainder of 223.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 2358 from 2581 leaves us with 223.
Fetch the next digit (1) from the dividend, attach it to 223 and continue: 2231 / 393

Let's proceed to step 6:
When dividing 2231 by 393, we get 5 with a remainder of 266.
Put 5 as the next digit of the answer. 
Result so far: 465.0
Subtracting 1965 from 2231 leaves us with 266.
Fetch the next digit (7) from the dividend, attach it to 266 and continue: 2667 / 393

Step 7:
When dividing 2667 by 393, we get 6 with a remainder of 309.
Use 6 as the next digit of our solution. 
Result so far: 4656.0
If we take 2358 away from 2667, we end up with 309.
Append the next digit (3) from the dividend to 309 and continue with: 3093 / 393

Let's proceed to step 8:
393 goes into 3093 7 times with a remainder of 342.
Put 7 as the next digit of the answer. 
Result so far: 46567.0
If we subtract 2751 from 3093, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 9:
When dividing 3420 by 393, we get 8 with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 46567.8
Deduct 3144 from 3420 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 10:
393 can be fit into 2760 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 46567.87
If we take 2751 away from 2760, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
393 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 46567.87
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
900 divided by 393 is 2 with a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 46567.8702
The remainder is 114 after subtracting 786 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 13:
The number 393 fits into 1140 2 times, leaving a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 46567.87022
If we subtract 786 from 1140, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 46567.87022 with a remaining 0.000354.
