We look at the division of 720400 by 87 
We want to figure out the number of times 720400 can be divided by 87.

Going ahead to step 1:
87 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 87

Step 2:
When dividing 72 by 87, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 87

Going ahead to step 3:
When dividing 720 by 87, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 8.0
If we take 696 away from 720, we end up with 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 87

Going ahead to step 4:
244 divided by 87 is 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 82.0
If we subtract 174 from 244, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 87

Step 5:
When dividing 700 by 87, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 828.0
Subtract 696 from 700 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 87

Moving on to step 6:
40 divided by 87 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8280.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 87, we get 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 8280.4
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
If we divide 520 by 87, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 8280.45
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
850 divided by 87 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 8280.459
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
87 goes into 670 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 8280.4597
If we subtract 609 from 670, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
610 divided by 87 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 8280.45977
The remainder is 1 after subtracting 609 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 8280.45977 and a remainder of 1e-06.
