We look at the division of 485091 by 87 
We're looking to find how many times 87 goes into 485091.

Going ahead to step 1:
4 divided by 87 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 87

On to step 2:
When dividing 48 by 87, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 87

Moving on to step 3:
485 divided by 87 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 435 from 485 to get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 87

Step 4:
The number 87 fits into 500 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 435 from 500 to get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 87

Going ahead to step 5:
659 divided by 87 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 557.0
Subtract 609 from 659 to get 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 87

Advancing to step 6:
If we divide 501 by 87, we get 5 and a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 5575.0
If we subtract 435 from 501, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
660 divided by 87 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 5575.7
If we take 609 away from 660, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 8:
510 divided by 87 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 5575.75
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
The number 87 fits into 750 8 times, leaving a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 5575.758
Subtract 696 from 750 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 87 fits into 540 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 5575.7586
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
87 goes into 180 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 5575.75862
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
60 divided by 87 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 5575.75862
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
600 divided by 87 is 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 5575.7586206
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 14:
When dividing 780 by 87, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 5575.75862068
Deduct 696 from 780 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 5575.75862068 and a remainder of 8.4e-08.
