143569 ÷ 36 
The aim is to understand the frequency of 36 in 143569.

Advancing to step 1:
When dividing 1 by 36, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 36

On to step 2:
36 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 36

Let's proceed to step 3:
If we divide 143 by 36, we get 3 and a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 108 from 143 to get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 36

Going ahead to step 4:
355 divided by 36 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 324 away from 355, we end up with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 36

Let's proceed to step 5:
36 can be fit into 316 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 398.0
Deduct 288 from 316 and we're left with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 36

Moving on to step 6:
When dividing 289 by 36, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 3988.0
The remainder is 1 after subtracting 288 from 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 36 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 3988.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
100 divided by 36 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3988.02
If we take 72 away from 100, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
36 can be fit into 280 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 3988.027
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
36 can be fit into 280 7 times, resulting in a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 3988.0277
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 3988.0277 with a remainder of 0.00028.
