85628520 ÷ 578 
Our goal is to divide 85628520 by 578.

Let's proceed to step 1:
578 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 578

Going ahead to step 2:
If we divide 85 by 578, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 578

Moving on to step 3:
856 divided by 578 is 1 with a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 578 from 856 leaves us with 278.
Append the next digit (2) from the dividend to 278 and continue with: 2782 / 578

On to step 4:
When dividing 2782 by 578, we get 4 with a remainder of 470.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2312 away from 2782, we end up with 470.
Bring next digit (8) of the dividend behind the 470 and repeat the process: 4708 / 578

Moving on to step 5:
578 goes into 4708 8 times with a remainder of 84.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 4624 from 4708 and we're left with 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 578

Going ahead to step 6:
If we divide 845 by 578, we get 1 and a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 1481.0
The remainder is 267 after subtracting 578 from 845.
Append the next digit (2) from the dividend to 267 and continue with: 2672 / 578

Going ahead to step 7:
The number 578 fits into 2672 4 times, leaving a remainder of 360.
Write down 4 as next digit of the result. 
Result so far: 14814.0
If we take 2312 away from 2672, we end up with 360.
Bring next digit (0) of the dividend behind the 360 and repeat the process: 3600 / 578

Step 8:
When dividing 3600 by 578, we get 6 with a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 148146.0
Subtracting 3468 from 3600 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
578 goes into 1320 2 times with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 148146.2
Subtracting 1156 from 1320 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 10:
If we divide 1640 by 578, we get 2 and a remainder of 484.
Record the quotient 2 as the next digit in the result. 
Result so far: 148146.22
The remainder is 484 after subtracting 1156 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final outcome is 148146.22, with a leftover of 0.484.
