Let's divide 143819 by 35
The aim is to understand the frequency of 35 in 143819.

Step 1:
1 divided by 35 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 35

Moving on to step 2:
The number 35 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 35

Step 3:
35 can be fit into 143 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 140 from 143 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 35

On to step 4:
If we divide 38 by 35, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 3 after subtracting 35 from 38.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 35

Moving on to step 5:
35 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 410.0
If we take 0 away from 31, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 35

Going ahead to step 6:
35 goes into 319 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 4109.0
If we take 315 away from 319, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 35 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 4109.1
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
35 goes into 50 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 4109.11
Subtracting 35 from 50 leaves us 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.

The final result is 4109.11 with a remainder of 0.015.
