We're dividing 19132806 by 393 
The aim is to understand the frequency of 393 in 19132806.

Going ahead to step 1:
1 divided by 393 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 393

Advancing to step 2:
393 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 393

Going ahead to step 3:
191 divided by 393 is 0 with a remainder of 191.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 191 leaves us with 191.
Take the next digit (3) from the dividend and append it to 191, then repeat: 1913 / 393

On to step 4:
393 can be fit into 1913 4 times, resulting in a remainder of 341.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1572 away from 1913, we end up with 341.
Grab the next digit (2) from the dividend, add it to 341, then carry on: 3412 / 393

On to step 5:
The number 393 fits into 3412 8 times, leaving a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 3144 from 3412 leaves us with 268.
Fetch the next digit (8) from the dividend, attach it to 268 and continue: 2688 / 393

Advancing to step 6:
2688 divided by 393 is 6 with a remainder of 330.
Put 6 as the next digit of the answer. 
Result so far: 486.0
If we subtract 2358 from 2688, we get 330.
Append the next digit (0) from the dividend to 330 and continue with: 3300 / 393

Advancing to step 7:
The number 393 fits into 3300 8 times, leaving a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 4868.0
Deduct 3144 from 3300 and we're left with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 393

Let's proceed to step 8:
When dividing 1566 by 393, we get 3 with a remainder of 387.
Put 3 as the next digit of the answer. 
Result so far: 48683.0
If we subtract 1179 from 1566, we get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 9:
3870 divided by 393 is 9 with a remainder of 333.
The next digit of our result is 9. 
Result so far: 48683.9
The remainder is 333 after subtracting 3537 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 10:
393 can be fit into 3330 8 times, resulting in a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 48683.98
Subtracting 3144 from 3330 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 11:
1860 divided by 393 is 4 with a remainder of 288.
The next digit of our result is 4. 
Result so far: 48683.984
If we take 1572 away from 1860, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 12:
If we divide 2880 by 393, we get 7 and a remainder of 129.
The number 7 becomes the next digit in our result. 
Result so far: 48683.9847
Subtract 2751 from 2880 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 13:
1290 divided by 393 is 3 with a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 48683.98473
The remainder is 111 after subtracting 1179 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 14:
When dividing 1110 by 393, we get 2 with a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 48683.984732
The remainder is 324 after subtracting 786 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 15:
If we divide 3240 by 393, we get 8 and a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 48683.9847328
Subtract 3144 from 3240 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 16:
The number 393 fits into 960 2 times, leaving a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 48683.98473282
Deduct 786 from 960 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final outcome is 48683.98473282, with a leftover of 1.74e-07.
