We're dividing 33402529 by 393 
The aim is to understand the frequency of 393 in 33402529.

On to step 1:
The number 393 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 393

Going ahead to step 2:
The number 393 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 393

Let's proceed to step 3:
If we divide 334 by 393, we get 0 and a remainder of 334.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 334 to get 334.
Include the next digit (0) from the dividend after 334, then repeat: 3340 / 393

Let's proceed to step 4:
393 goes into 3340 8 times with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 3144 away from 3340, we end up with 196.
Bring next digit (2) of the dividend behind the 196 and repeat the process: 1962 / 393

Let's proceed to step 5:
1962 divided by 393 is 4 with a remainder of 390.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 1572 from 1962 leaves us with 390.
Include the next digit (5) from the dividend after 390, then repeat: 3905 / 393

On to step 6:
393 goes into 3905 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
Subtract 3537 from 3905 to get 368.
Grab the next digit (2) from the dividend, add it to 368, then carry on: 3682 / 393

Advancing to step 7:
393 can be fit into 3682 9 times, resulting in a remainder of 145.
The next digit of our result is 9. 
Result so far: 8499.0
The remainder is 145 after subtracting 3537 from 3682.
Fetch the next digit (9) from the dividend, attach it to 145 and continue: 1459 / 393

Moving on to step 8:
When dividing 1459 by 393, we get 3 with a remainder of 280.
Put 3 as the next digit of the answer. 
Result so far: 84993.0
Subtracting 1179 from 1459 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 9:
393 goes into 2800 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 84993.7
If we take 2751 away from 2800, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
490 divided by 393 is 1 with a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 84993.71
The remainder is 97 after subtracting 393 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 11:
If we divide 970 by 393, we get 2 and a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 84993.712
If we take 786 away from 970, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
If we divide 1840 by 393, we get 4 and a remainder of 268.
Record the quotient 4 as the next digit in the result. 
Result so far: 84993.7124
Subtracting 1572 from 1840 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 13:
If we divide 2680 by 393, we get 6 and a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 84993.71246
Subtracting 2358 from 2680 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 14:
When dividing 3220 by 393, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 84993.712468
If we take 3144 away from 3220, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 15:
If we divide 760 by 393, we get 1 and a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 84993.7124681
Deduct 393 from 760 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 16:
393 goes into 3670 9 times with a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 84993.71246819
The remainder is 133 after subtracting 3537 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The final result is 84993.71246819 with a remainder of 1.33e-07.
