51458 ÷ 18 
Let's see how many times 18 fits into 51458.

Going ahead to step 1:
When dividing 5 by 18, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 18

Step 2:
18 goes into 51 2 times with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 36 from 51 to get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 18

Going ahead to step 3:
If we divide 154 by 18, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 144 from 154 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 18

Going ahead to step 4:
18 can be fit into 105 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 285.0
Subtract 90 from 105 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 18

Let's proceed to step 5:
18 can be fit into 158 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 2858.0
Deduct 144 from 158 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
If we divide 140 by 18, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2858.7
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2858.77
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 2858.77 with a balance of 0.014.
