258376 divided by 45 
Our goal is to divide 258376 by 45.

Advancing to step 1:
45 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 45

Moving on to step 2:
25 divided by 45 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 45

Step 3:
The number 45 fits into 258 5 times, leaving a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 225 from 258 leaves us with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 45

Going ahead to step 4:
If we divide 333 by 45, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 57.0
The remainder is 18 after subtracting 315 from 333.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 45

Moving on to step 5:
The number 45 fits into 187 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 574.0
If we subtract 180 from 187, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 45

Advancing to step 6:
The number 45 fits into 76 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 5741.0
If we take 45 away from 76, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
45 goes into 310 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 5741.6
Deduct 270 from 310 and we're left 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.

Moving on to step 8:
400 divided by 45 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 5741.68
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
45 goes into 400 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 5741.688
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 5741.688 with a remaining 0.004.
