We look at the division of 85087509 by 631 
Let's see how many times 631 fits into 85087509.

Advancing to step 1:
631 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 631

Moving on to step 2:
When dividing 85 by 631, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 631

Advancing to step 3:
The number 631 fits into 850 1 times, leaving a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 631 away from 850, we end up with 219.
Include the next digit (8) from the dividend after 219, then repeat: 2198 / 631

Going ahead to step 4:
When dividing 2198 by 631, we get 3 with a remainder of 305.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1893 from 2198, we get 305.
Append the next digit (7) from the dividend to 305 and continue with: 3057 / 631

On to step 5:
631 can be fit into 3057 4 times, resulting in a remainder of 533.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we subtract 2524 from 3057, we get 533.
Append the next digit (5) from the dividend to 533 and continue with: 5335 / 631

Moving on to step 6:
When dividing 5335 by 631, we get 8 with a remainder of 287.
The next digit of our result is 8. 
Result so far: 1348.0
Subtracting 5048 from 5335 leaves us with 287.
Grab the next digit (0) from the dividend, add it to 287, then carry on: 2870 / 631

Step 7:
The number 631 fits into 2870 4 times, leaving a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 13484.0
Subtracting 2524 from 2870 leaves us with 346.
Append the next digit (9) from the dividend to 346 and continue with: 3469 / 631

Advancing to step 8:
If we divide 3469 by 631, we get 5 and a remainder of 314.
Use 5 as the next digit of our solution. 
Result so far: 134845.0
Deduct 3155 from 3469 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 9:
When dividing 3140 by 631, we get 4 with a remainder of 616.
Write down 4 as next digit of the result. 
Result so far: 134845.4
Subtract 2524 from 3140 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 10:
631 goes into 6160 9 times with a remainder of 481.
The next digit of our result is 9. 
Result so far: 134845.49
Subtract 5679 from 6160 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 11:
The number 631 fits into 4810 7 times, leaving a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 134845.497
Subtract 4417 from 4810 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 12:
When dividing 3930 by 631, we get 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 134845.4976
If we take 3786 away from 3930, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
631 goes into 1440 2 times with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 134845.49762
The remainder is 178 after subtracting 1262 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 14:
The number 631 fits into 1780 2 times, leaving a remainder of 518.
The next digit of our result is 2. 
Result so far: 134845.497622
Deduct 1262 from 1780 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final result is 134845.497622 with a remainder of 5.18e-05.
