We look at the division of 35318713 by 354 
The aim is to understand the frequency of 354 in 35318713.

Step 1:
If we divide 3 by 354, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 354

Advancing to step 2:
35 divided by 354 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 354

Going ahead to step 3:
If we divide 353 by 354, we get 0 and a remainder of 353.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 353 leaves us with 353.
Take the next digit (1) from the dividend and append it to 353, then repeat: 3531 / 354

Going ahead to step 4:
When dividing 3531 by 354, we get 9 with a remainder of 345.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 3186 from 3531 leaves us with 345.
Fetch the next digit (8) from the dividend, attach it to 345 and continue: 3458 / 354

Moving on to step 5:
When dividing 3458 by 354, we get 9 with a remainder of 272.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 3186 from 3458 to get 272.
Include the next digit (7) from the dividend after 272, then repeat: 2727 / 354

Step 6:
2727 divided by 354 is 7 with a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 997.0
If we take 2478 away from 2727, we end up with 249.
Take the next digit (1) from the dividend and append it to 249, then repeat: 2491 / 354

Advancing to step 7:
If we divide 2491 by 354, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 9977.0
If we take 2478 away from 2491, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 354

Advancing to step 8:
When dividing 133 by 354, we get 0 with a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 99770.0
Subtracting 0 from 133 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 9:
354 can be fit into 1330 3 times, resulting in a remainder of 268.
The number 3 becomes the next digit in our result. 
Result so far: 99770.3
The remainder is 268 after subtracting 1062 from 1330.
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 10:
The number 354 fits into 2680 7 times, leaving a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 99770.37
The remainder is 202 after subtracting 2478 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
2020 divided by 354 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 99770.375
Subtracting 1770 from 2020 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
354 goes into 2500 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 99770.3757
Subtract 2478 from 2500 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
354 goes into 220 0 times with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 99770.3757
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
354 can be fit into 2200 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 99770.375706
If we take 2124 away from 2200, 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:
760 divided by 354 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 99770.3757062
If we subtract 708 from 760, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
If we divide 520 by 354, we get 1 and a remainder of 166.
The next digit of our result is 1. 
Result so far: 99770.37570621
If we take 354 away from 520, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 99770.37570621 with a remainder of 1.66e-07.
