258075 divided by 42 
We're looking to find how many times 42 goes into 258075.

Moving on to step 1:
2 divided by 42 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 42

Advancing to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 42

On to step 3:
If we divide 258 by 42, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 252 from 258 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 42

On to step 4:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 42 from 60, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 42

Step 5:
If we divide 187 by 42, we get 4 and a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 614.0
Deduct 168 from 187 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 42

Step 6:
195 divided by 42 is 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 6144.0
If we take 168 away from 195, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
42 can be fit into 270 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6144.6
Deduct 252 from 270 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 6144.64
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 6144.642
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 6144.6428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 6144.64285
If we take 210 away from 240, we end up 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.

Going ahead to step 12:
42 goes into 300 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 6144.642857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
42 goes into 60 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 6144.6428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 6144.64285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 6144.64285714, and the remainder is 1.2e-08.
