We're dividing 258457 by 53 
We're looking to find how many times 53 goes into 258457.

Step 1:
53 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 53

Going ahead to step 2:
If we divide 25 by 53, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 53

Moving on to step 3:
53 goes into 258 4 times with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 212 from 258 and we're left with 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 53

Let's proceed to step 4:
If we divide 464 by 53, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 424 from 464 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 53

Moving on to step 5:
The number 53 fits into 405 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Deduct 371 from 405 and we're left with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 53

Moving on to step 6:
53 goes into 347 6 times with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 4876.0
The remainder is 29 after subtracting 318 from 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
290 divided by 53 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4876.5
The remainder is 25 after subtracting 265 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
If we divide 250 by 53, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 4876.54
The remainder is 38 after subtracting 212 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 53, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4876.547
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
When dividing 90 by 53, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 4876.5471
Deduct 53 from 90 and we're left 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.

Advancing to step 11:
53 goes into 370 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 4876.54716
Subtract 318 from 370 to 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.

Moving on to step 12:
53 can be fit into 520 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 4876.547169
Subtract 477 from 520 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
The number 53 fits into 430 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 4876.5471698
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
60 divided by 53 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 4876.54716981
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 4876.54716981 with a remainder of 7e-09.
