485090 ÷ 85 
We want to figure out the number of times 485090 can be divided by 85.

Advancing to step 1:
85 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 85

Let's proceed to step 2:
When dividing 48 by 85, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 85

On to step 3:
85 can be fit into 485 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 60 after subtracting 425 from 485.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 85

Moving on to step 4:
85 can be fit into 600 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
The remainder is 5 after subtracting 595 from 600.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 85

Advancing to step 5:
If we divide 59 by 85, we get 0 and a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 570.0
Deduct 0 from 59 and we're left with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 85

Moving on to step 6:
The number 85 fits into 590 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 5706.0
Subtracting 510 from 590 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 5706.9
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
85 goes into 350 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 5706.94
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 5706.941
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 85 is 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 5706.9411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 5706.9411 with a remaining 0.00065.
