We're dividing 258203 by 54 
We want to divide 258203 by 54.

Step 1:
54 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 54

Step 2:
25 divided by 54 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 54

Advancing to step 3:
54 can be fit into 258 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 216 from 258 and we're left with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 54

Going ahead to step 4:
54 goes into 422 7 times with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 378 from 422 leaves us with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 54

Advancing to step 5:
440 divided by 54 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 478.0
If we take 432 away from 440, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 54

Let's proceed to step 6:
54 goes into 83 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 4781.0
Subtracting 54 from 83 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
When dividing 290 by 54, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4781.5
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 4781.53
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 54 fits into 380 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 4781.537
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 54 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 4781.537
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 54, we get 3 and a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 4781.53703
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 54, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 4781.537037
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 54 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4781.537037
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
200 divided by 54 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 4781.53703703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 4781.53703703 with a remainder of 3.8e-08.
