258235 divided by 57 
We want to figure out the number of times 258235 can be divided by 57.

Advancing to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 57

Advancing to step 2:
57 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 57

Step 3:
57 goes into 258 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 228 from 258 leaves us with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 57

On to step 4:
When dividing 302 by 57, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 285 from 302 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 57

Step 5:
When dividing 173 by 57, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 453.0
Subtracting 171 from 173 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 57

On to step 6:
57 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 4530.0
If we take 0 away from 25, we end up 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.

On to step 7:
When dividing 250 by 57, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 4530.4
Deduct 228 from 250 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
57 goes into 220 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 4530.43
If we take 171 away from 220, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
57 can be fit into 490 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 4530.438
The remainder is 34 after subtracting 456 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
If we divide 340 by 57, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 4530.4385
If we subtract 285 from 340, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
57 goes into 550 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 4530.43859
If we take 513 away from 550, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
370 divided by 57 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 4530.438596
If we take 342 away from 370, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
57 goes into 280 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 4530.4385964
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
520 divided by 57 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 4530.43859649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 4530.43859649 with a remaining 7e-09.
