We look at the division of 551187 by 85 
We want to divide 551187 by 85.

Step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 85

Advancing to step 2:
The number 85 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 85

Let's proceed to step 3:
551 divided by 85 is 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 510 from 551 to get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 85

Going ahead to step 4:
85 goes into 411 4 times with a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 340 from 411 leaves us with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 85

Step 5:
The number 85 fits into 718 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we take 680 away from 718, we end up with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 85

On to step 6:
85 can be fit into 387 4 times, resulting in a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 6484.0
Deduct 340 from 387 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
When dividing 470 by 85, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6484.5
If we take 425 away from 470, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
450 divided by 85 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6484.55
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 6484.55 and a remainder of 0.025.
