We're dividing 231379 by 75 
We want to figure out the number of times 231379 can be divided by 75.

Advancing to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 75

Going ahead to step 2:
If we divide 23 by 75, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 75

Let's proceed to step 3:
75 can be fit into 231 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 6 after subtracting 225 from 231.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 75

On to step 4:
When dividing 63 by 75, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 63, we end up with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 75

Step 5:
75 can be fit into 637 8 times, resulting in a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 308.0
Subtract 600 from 637 to get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 75

Let's proceed to step 6:
The number 75 fits into 379 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 3085.0
Deduct 375 from 379 and we're left 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.

Advancing to step 7:
When dividing 40 by 75, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3085.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 75 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3085.05
The remainder is 25 after subtracting 375 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 3085.053
Deduct 225 from 250 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.

Moving on to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3085.0533
Subtract 225 from 250 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.

Our division results in 3085.0533 with a remaining 0.00025.
