We're dividing 285972 by 35 
The aim is to understand the frequency of 35 in 285972.

Let's proceed to step 1:
2 divided by 35 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 35

Going ahead to step 2:
35 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 35

Let's proceed to step 3:
The number 35 fits into 285 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 280 away from 285, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 35

Moving on to step 4:
If we divide 59 by 35, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 35 from 59, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 35

Going ahead to step 5:
247 divided by 35 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 817.0
If we subtract 245 from 247, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 35

Step 6:
If we divide 22 by 35, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 8170.0
If we subtract 0 from 22, we 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.

Let's proceed to step 7:
If we divide 220 by 35, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 8170.6
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 35, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 8170.62
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
35 goes into 300 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8170.628
Subtracting 280 from 300 leaves us 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.

Step 10:
200 divided by 35 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8170.6285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
250 divided by 35 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 8170.62857
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.

Advancing to step 12:
The number 35 fits into 50 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 8170.628571
If we take 35 away from 50, we end up 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.

On to step 13:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 8170.6285714
If we take 140 away from 150, 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.

Step 14:
When dividing 100 by 35, we get 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 8170.62857142
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 8170.62857142 with a remainder of 3e-08.
