We look at the division of 181911 by 35 
The aim is to understand the frequency of 35 in 181911.

Going ahead to step 1:
1 divided by 35 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 35

On to step 2:
If we divide 18 by 35, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 35

Going ahead to step 3:
35 can be fit into 181 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 175 from 181 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 35

Step 4:
69 divided by 35 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 35 from 69 to get 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 35

Advancing to step 5:
35 goes into 341 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
If we take 315 away from 341, we end up with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 35

Moving on to step 6:
261 divided by 35 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 5197.0
Subtracting 245 from 261 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 35 fits into 160 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 5197.4
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
35 goes into 200 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5197.45
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
The number 35 fits into 250 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 5197.457
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
When dividing 50 by 35, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 5197.4571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 5197.45714
Deduct 140 from 150 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 35, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 5197.457142
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
35 goes into 300 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 5197.4571428
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
When dividing 200 by 35, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5197.45714285
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 5197.45714285 and a remainder of 2.5e-08.
