We look at the division of 18385566 by 578 
We want to figure out the number of times 18385566 can be divided by 578.

Advancing to step 1:
The number 578 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 578

Advancing to step 2:
When dividing 18 by 578, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 578

Moving on to step 3:
578 goes into 183 0 times with a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Grab the next digit (8) from the dividend, add it to 183, then carry on: 1838 / 578

On to step 4:
When dividing 1838 by 578, we get 3 with a remainder of 104.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1734 from 1838, we get 104.
Fetch the next digit (5) from the dividend, attach it to 104 and continue: 1045 / 578

On to step 5:
The number 578 fits into 1045 1 times, leaving a remainder of 467.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 578 from 1045, we get 467.
Take the next digit (5) from the dividend and append it to 467, then repeat: 4675 / 578

Going ahead to step 6:
578 goes into 4675 8 times with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 318.0
If we take 4624 away from 4675, we end up with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 578

Let's proceed to step 7:
516 divided by 578 is 0 with a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 3180.0
Subtracting 0 from 516 leaves us with 516.
Grab the next digit (6) from the dividend, add it to 516, then carry on: 5166 / 578

Going ahead to step 8:
578 goes into 5166 8 times with a remainder of 542.
The next digit of our result is 8. 
Result so far: 31808.0
If we take 4624 away from 5166, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 9:
If we divide 5420 by 578, we get 9 and a remainder of 218.
Write down 9 as next digit of the result. 
Result so far: 31808.9
Deduct 5202 from 5420 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 10:
The number 578 fits into 2180 3 times, leaving a remainder of 446.
Write down 3 as next digit of the result. 
Result so far: 31808.93
The remainder is 446 after subtracting 1734 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 11:
If we divide 4460 by 578, we get 7 and a remainder of 414.
Record the quotient 7 as the next digit in the result. 
Result so far: 31808.937
The remainder is 414 after subtracting 4046 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 12:
If we divide 4140 by 578, we get 7 and a remainder of 94.
The next digit of our result is 7. 
Result so far: 31808.9377
Subtracting 4046 from 4140 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 31808.9377 with a balance of 0.00094.
