We look at the division of 59166056 by 393 
The aim is to understand the frequency of 393 in 59166056.

Advancing to step 1:
393 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 393

Moving on to step 2:
The number 393 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 393

Advancing to step 3:
When dividing 591 by 393, we get 1 with a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 393 away from 591, we end up with 198.
Include the next digit (6) from the dividend after 198, then repeat: 1986 / 393

On to step 4:
393 goes into 1986 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 1965 away from 1986, we end up with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 393

Going ahead to step 5:
If we divide 216 by 393, we get 0 and a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we subtract 0 from 216, we get 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 393

Moving on to step 6:
2160 divided by 393 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 1505.0
Subtract 1965 from 2160 to get 195.
Grab the next digit (5) from the dividend, add it to 195, then carry on: 1955 / 393

Advancing to step 7:
393 goes into 1955 4 times with a remainder of 383.
The next digit of our result is 4. 
Result so far: 15054.0
If we subtract 1572 from 1955, we get 383.
Fetch the next digit (6) from the dividend, attach it to 383 and continue: 3836 / 393

Let's proceed to step 8:
When dividing 3836 by 393, we get 9 with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 150549.0
Subtract 3537 from 3836 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 9:
2990 divided by 393 is 7 with a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 150549.7
Subtract 2751 from 2990 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 10:
393 goes into 2390 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 150549.76
Subtract 2358 from 2390 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
393 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 150549.76
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
393 can be fit into 3200 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 150549.7608
If we take 3144 away from 3200, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
560 divided by 393 is 1 with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 150549.76081
Deduct 393 from 560 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 14:
393 goes into 1670 4 times with a remainder of 98.
The next digit of our result is 4. 
Result so far: 150549.760814
If we subtract 1572 from 1670, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 15:
If we divide 980 by 393, we get 2 and a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 150549.7608142
Subtract 786 from 980 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 16:
When dividing 1940 by 393, we get 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 150549.76081424
Subtracting 1572 from 1940 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 150549.76081424 with a remainder of 3.68e-07.
