We're dividing 33333000 by 355 
The aim is to understand the frequency of 355 in 33333000.

Step 1:
The number 355 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 355

Step 2:
33 divided by 355 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 355

Moving on to step 3:
If we divide 333 by 355, we get 0 and a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 333 to get 333.
Grab the next digit (3) from the dividend, add it to 333, then carry on: 3333 / 355

Let's proceed to step 4:
When dividing 3333 by 355, we get 9 with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 3195 from 3333 leaves us with 138.
Include the next digit (3) from the dividend after 138, then repeat: 1383 / 355

Moving on to step 5:
1383 divided by 355 is 3 with a remainder of 318.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtracting 1065 from 1383 leaves us with 318.
Fetch the next digit (0) from the dividend, attach it to 318 and continue: 3180 / 355

Moving on to step 6:
If we divide 3180 by 355, we get 8 and a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 938.0
If we subtract 2840 from 3180, we get 340.
Fetch the next digit (0) from the dividend, attach it to 340 and continue: 3400 / 355

On to step 7:
355 can be fit into 3400 9 times, resulting in a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 9389.0
Subtract 3195 from 3400 to get 205.
Include the next digit (0) from the dividend after 205, then repeat: 2050 / 355

Step 8:
2050 divided by 355 is 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 93895.0
Subtracting 1775 from 2050 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
The number 355 fits into 2750 7 times, leaving a remainder of 265.
The next digit of our result is 7. 
Result so far: 93895.7
If we take 2485 away from 2750, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
355 can be fit into 2650 7 times, resulting in a remainder of 165.
Put 7 as the next digit of the answer. 
Result so far: 93895.77
If we take 2485 away from 2650, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

After the division, we end up with 93895.77 and a remainder of 0.165.
