We look at the division of 22701990 by 335 
The aim is to understand the frequency of 335 in 22701990.

Let's proceed to step 1:
335 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 335

Moving on to step 2:
The number 335 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 335

Moving on to step 3:
When dividing 227 by 335, we get 0 with a remainder of 227.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 227 to get 227.
Fetch the next digit (0) from the dividend, attach it to 227 and continue: 2270 / 335

Moving on to step 4:
2270 divided by 335 is 6 with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 2010 from 2270 and we're left with 260.
Fetch the next digit (1) from the dividend, attach it to 260 and continue: 2601 / 335

On to step 5:
The number 335 fits into 2601 7 times, leaving a remainder of 256.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we take 2345 away from 2601, we end up with 256.
Grab the next digit (9) from the dividend, add it to 256, then carry on: 2569 / 335

On to step 6:
The number 335 fits into 2569 7 times, leaving a remainder of 224.
The number 7 becomes the next digit in our result. 
Result so far: 677.0
Subtract 2345 from 2569 to get 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 335

On to step 7:
The number 335 fits into 2249 6 times, leaving a remainder of 239.
The next digit of our result is 6. 
Result so far: 6776.0
Deduct 2010 from 2249 and we're left with 239.
Bring next digit (0) of the dividend behind the 239 and repeat the process: 2390 / 335

Advancing to step 8:
335 can be fit into 2390 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 67767.0
If we take 2345 away from 2390, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
335 goes into 450 1 times with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 67767.1
Deduct 335 from 450 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
335 can be fit into 1150 3 times, resulting in a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 67767.13
Subtract 1005 from 1150 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
335 goes into 1450 4 times with a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 67767.134
If we subtract 1340 from 1450, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
335 goes into 1100 3 times with a remainder of 95.
The next digit of our result is 3. 
Result so far: 67767.1343
Deduct 1005 from 1100 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
335 can be fit into 950 2 times, resulting in a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 67767.13432
Subtract 670 from 950 to get 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 14:
The number 335 fits into 2800 8 times, leaving a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 67767.134328
If we take 2680 away from 2800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
The number 335 fits into 1200 3 times, leaving a remainder of 195.
The next digit of our result is 3. 
Result so far: 67767.1343283
The remainder is 195 after subtracting 1005 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 16:
1950 divided by 335 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 67767.13432835
Deduct 1675 from 1950 and we're left 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.

The final result is 67767.13432835 with a remainder of 2.75e-07.
