124590 divided by 54 
Our goal is to divide 124590 by 54.

Moving on to step 1:
The number 54 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 54

Let's proceed to step 2:
54 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 54

Step 3:
If we divide 124 by 54, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 108 from 124 leaves us with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 54

Let's proceed to step 4:
165 divided by 54 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 162 from 165 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 54

Step 5:
When dividing 39 by 54, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 54

Advancing to step 6:
The number 54 fits into 390 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 2307.0
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 54 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2307.2
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
54 goes into 120 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2307.22
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2307.22 and a remainder of 0.012.
