We're dividing 87532058 by 3 
The aim is to understand the frequency of 3 in 87532058.

Let's proceed to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Going ahead to step 2:
If we divide 27 by 3, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 27 from 27 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Going ahead to step 3:
3 goes into 5 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Deduct 3 from 5 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Moving on to step 4:
3 goes into 23 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 2917.0
Deduct 21 from 23 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Advancing to step 5:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 29177.0
Subtracting 21 from 22 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

On to step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 291773.0
Deduct 9 from 10 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Let's proceed to step 7:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2917735.0
If we take 15 away from 15, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Moving on to step 8:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 29177352.0
If we subtract 6 from 8, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 29177352.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 29177352.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 29177352.66 with a remainder of 0.002.
