545399 ÷ 46 
We want to figure out the number of times 545399 can be divided by 46.

Step 1:
The number 46 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 46

Going ahead to step 2:
54 divided by 46 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 46 from 54, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 46

Moving on to step 3:
46 goes into 85 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 46 away from 85, we end up with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 46

Moving on to step 4:
46 can be fit into 393 8 times, resulting in a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 118.0
If we take 368 away from 393, we end up with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 46

On to step 5:
259 divided by 46 is 5 with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 1185.0
Subtract 230 from 259 to get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 46

Let's proceed to step 6:
The number 46 fits into 299 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 11856.0
If we take 276 away from 299, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 46, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11856.5
Subtracting 230 from 230 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
46 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11856.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
46 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11856.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11856.5 with a remainder of 0.0.
