We look at the division of 85870247 by 485 
Our goal is to divide 85870247 by 485.

Let's proceed to step 1:
When dividing 8 by 485, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 485

Let's proceed to step 2:
85 divided by 485 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 485

Advancing to step 3:
If we divide 858 by 485, we get 1 and a remainder of 373.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 485 from 858 to get 373.
Take the next digit (7) from the dividend and append it to 373, then repeat: 3737 / 485

Step 4:
The number 485 fits into 3737 7 times, leaving a remainder of 342.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 3395 away from 3737, we end up with 342.
Include the next digit (0) from the dividend after 342, then repeat: 3420 / 485

Step 5:
485 goes into 3420 7 times with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
If we subtract 3395 from 3420, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 485

Moving on to step 6:
The number 485 fits into 252 0 times, leaving a remainder of 252.
Write down 0 as next digit of the result. 
Result so far: 1770.0
Subtracting 0 from 252 leaves us with 252.
Take the next digit (4) from the dividend and append it to 252, then repeat: 2524 / 485

Let's proceed to step 7:
The number 485 fits into 2524 5 times, leaving a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 17705.0
The remainder is 99 after subtracting 2425 from 2524.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 485

Going ahead to step 8:
If we divide 997 by 485, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 177052.0
Subtracting 970 from 997 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 485, we get 0 and a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 177052.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
2700 divided by 485 is 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 177052.05
The remainder is 275 after subtracting 2425 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
485 goes into 2750 5 times with a remainder of 325.
The next digit of our result is 5. 
Result so far: 177052.055
If we subtract 2425 from 2750, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final result is 177052.055 with a remainder of 0.0325.
