We look at the division of 631551 by 87 
We want to figure out the number of times 631551 can be divided by 87.

Going ahead to step 1:
87 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 87

Going ahead to step 2:
When dividing 63 by 87, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 87

On to step 3:
If we divide 631 by 87, we get 7 and a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 609 from 631 and we're left with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 87

Moving on to step 4:
87 goes into 225 2 times with a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtracting 174 from 225 leaves us with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 87

Step 5:
515 divided by 87 is 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 725.0
If we subtract 435 from 515, we get 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 87

On to step 6:
The number 87 fits into 801 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 7259.0
The remainder is 18 after subtracting 783 from 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 87, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 7259.2
Deduct 174 from 180 and we're left 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.

On to step 8:
60 divided by 87 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7259.2
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
87 goes into 600 6 times with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 7259.206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
If we divide 780 by 87, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 7259.2068
If we take 696 away from 780, we end up 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.

Step 11:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 7259.20689
Deduct 783 from 840 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
The number 87 fits into 570 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 7259.206896
The remainder is 48 after subtracting 522 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
If we divide 480 by 87, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 7259.2068965
Subtracting 435 from 480 leaves us 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.

Step 14:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7259.20689655
Subtract 435 from 450 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 7259.20689655 with a remainder of 1.5e-08.
