457534 ÷ 3 
Let's see how many times 3 fits into 457534.

Going ahead to step 1:
3 goes into 4 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Moving on to step 2:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 15 from 15, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Let's proceed to step 3:
When dividing 7 by 3, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 6 from 7 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

On to step 4:
When dividing 15 by 3, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1525.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Let's proceed to step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 15251.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Step 6:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 152511.0
If we subtract 3 from 4, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 152511.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 152511.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 152511.33, with a leftover of 0.001.
