We're dividing 45646998 by 578 
Our goal is to divide 45646998 by 578.

Let's proceed to step 1:
The number 578 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 578

Advancing to step 2:
When dividing 45 by 578, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 578

Step 3:
578 goes into 456 0 times with a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 456 after subtracting 0 from 456.
Take the next digit (4) from the dividend and append it to 456, then repeat: 4564 / 578

Step 4:
578 can be fit into 4564 7 times, resulting in a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4046 from 4564 to get 518.
Append the next digit (6) from the dividend to 518 and continue with: 5186 / 578

Let's proceed to step 5:
If we divide 5186 by 578, we get 8 and a remainder of 562.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 4624 from 5186 and we're left with 562.
Bring next digit (9) of the dividend behind the 562 and repeat the process: 5629 / 578

Moving on to step 6:
5629 divided by 578 is 9 with a remainder of 427.
Use 9 as the next digit of our solution. 
Result so far: 789.0
The remainder is 427 after subtracting 5202 from 5629.
Include the next digit (9) from the dividend after 427, then repeat: 4279 / 578

Moving on to step 7:
When dividing 4279 by 578, we get 7 with a remainder of 233.
Put 7 as the next digit of the answer. 
Result so far: 7897.0
Subtracting 4046 from 4279 leaves us with 233.
Bring next digit (8) of the dividend behind the 233 and repeat the process: 2338 / 578

On to step 8:
When dividing 2338 by 578, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 78974.0
The remainder is 26 after subtracting 2312 from 2338.
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 9:
If we divide 260 by 578, we get 0 and a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 78974.0
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
When dividing 2600 by 578, we get 4 with a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 78974.04
Subtracting 2312 from 2600 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 11:
578 can be fit into 2880 4 times, resulting in a remainder of 568.
Put 4 as the next digit of the answer. 
Result so far: 78974.044
If we take 2312 away from 2880, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 78974.044 with a remainder of 0.0568.
