We look at the division of 20113407 by 354 
The aim is to understand the frequency of 354 in 20113407.

On to step 1:
354 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 354

Moving on to step 2:
354 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 354

Step 3:
When dividing 201 by 354, we get 0 with a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Include the next digit (1) from the dividend after 201, then repeat: 2011 / 354

Going ahead to step 4:
354 goes into 2011 5 times with a remainder of 241.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 241 after subtracting 1770 from 2011.
Take the next digit (3) from the dividend and append it to 241, then repeat: 2413 / 354

Going ahead to step 5:
If we divide 2413 by 354, we get 6 and a remainder of 289.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 289 after subtracting 2124 from 2413.
Take the next digit (4) from the dividend and append it to 289, then repeat: 2894 / 354

On to step 6:
When dividing 2894 by 354, we get 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 568.0
Subtracting 2832 from 2894 leaves us with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 354

On to step 7:
If we divide 620 by 354, we get 1 and a remainder of 266.
Put 1 as the next digit of the answer. 
Result so far: 5681.0
Subtract 354 from 620 to get 266.
Grab the next digit (7) from the dividend, add it to 266, then carry on: 2667 / 354

Advancing to step 8:
354 goes into 2667 7 times with a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 56817.0
Subtract 2478 from 2667 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 9:
If we divide 1890 by 354, we get 5 and a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 56817.5
Deduct 1770 from 1890 and we're left 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 10:
354 goes into 1200 3 times with a remainder of 138.
The number 3 becomes the next digit in our result. 
Result so far: 56817.53
The remainder is 138 after subtracting 1062 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 11:
354 goes into 1380 3 times with a remainder of 318.
Use 3 as the next digit of our solution. 
Result so far: 56817.533
If we take 1062 away from 1380, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

In conclusion, the division gives 56817.533 with a balance of 0.0318.
