578485 ÷ 46 
Our goal is to divide 578485 by 46.

Step 1:
The number 46 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 46

Moving on to step 2:
57 divided by 46 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 46 from 57, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 46

On to step 3:
The number 46 fits into 118 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 92 from 118 to get 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 46

Advancing to step 4:
The number 46 fits into 264 5 times, leaving a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 230 from 264 leaves us with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 46

Going ahead to step 5:
46 can be fit into 348 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
Subtract 322 from 348 to get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 46

Let's proceed to step 6:
265 divided by 46 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 12575.0
If we subtract 230 from 265, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
350 divided by 46 is 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 12575.7
Deduct 322 from 350 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
The number 46 fits into 280 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12575.76
Deduct 276 from 280 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
46 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12575.76
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
46 can be fit into 400 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 12575.7608
Deduct 368 from 400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 46, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 12575.76086
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
If we divide 440 by 46, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 12575.760869
If we take 414 away from 440, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
When dividing 260 by 46, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 12575.7608695
Deduct 230 from 260 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
When dividing 300 by 46, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 12575.76086956
Subtracting 276 from 300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 12575.76086956 with a remainder of 2.4e-08.
