258235 ÷ 71 
We're looking to find how many times 71 goes into 258235.

Step 1:
2 divided by 71 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 71

On to step 2:
When dividing 25 by 71, we get 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.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 71

Let's proceed to step 3:
The number 71 fits into 258 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 213 from 258, we get 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 71

Moving on to step 4:
71 goes into 452 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we take 426 away from 452, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 71

Going ahead to step 5:
If we divide 263 by 71, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 363.0
Subtract 213 from 263 to get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 71

Let's proceed to step 6:
71 goes into 505 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 3637.0
Subtract 497 from 505 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
If we divide 80 by 71, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 3637.1
Subtract 71 from 80 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
71 goes into 90 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 3637.11
Deduct 71 from 90 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 3637.11, with a leftover of 0.019.
