We divide 688531 by 87
We're looking to find how many times 87 goes into 688531.

Going ahead to step 1:
6 divided by 87 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 87

On to step 2:
If we divide 68 by 87, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 87

Step 3:
87 goes into 688 7 times with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 609 from 688 and we're left with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 87

Let's proceed to step 4:
When dividing 795 by 87, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 783 from 795, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 87

Advancing to step 5:
123 divided by 87 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 791.0
Deduct 87 from 123 and we're left with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 87

On to step 6:
87 goes into 361 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 7914.0
Subtract 348 from 361 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 87 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 7914.1
The remainder is 43 after subtracting 87 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
When dividing 430 by 87, we get 4 with a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 7914.14
Subtracting 348 from 430 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
If we divide 820 by 87, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 7914.149
If we take 783 away from 820, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
The number 87 fits into 370 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 7914.1494
Subtract 348 from 370 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
If we divide 220 by 87, we get 2 and a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 7914.14942
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
87 can be fit into 460 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7914.149425
Subtracting 435 from 460 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
250 divided by 87 is 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 7914.1494252
If we take 174 away from 250, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
If we divide 760 by 87, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 7914.14942528
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 7914.14942528, with a leftover of 6.4e-08.
