787800 ÷ 87 
We want to figure out the number of times 787800 can be divided by 87.

Let's proceed to step 1:
7 divided by 87 is 0 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 (8) from the dividend after 7, then repeat: 78 / 87

On to step 2:
The number 87 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 87

Moving on to step 3:
When dividing 787 by 87, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 783 from 787 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 87

On to step 4:
When dividing 48 by 87, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 48 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 87

Let's proceed to step 5:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 905.0
Subtracting 435 from 480 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 87

Moving on to step 6:
450 divided by 87 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9055.0
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 87 fits into 150 1 times, leaving a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 9055.1
Subtracting 87 from 150 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
When dividing 630 by 87, we get 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 9055.17
The remainder is 21 after subtracting 609 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
When dividing 210 by 87, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 9055.172
If we subtract 174 from 210, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
The number 87 fits into 360 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 9055.1724
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
When dividing 120 by 87, we get 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 9055.17241
Subtracting 87 from 120 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
330 divided by 87 is 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 9055.172413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 13:
87 goes into 690 7 times with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 9055.1724137
Subtract 609 from 690 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 14:
If we divide 810 by 87, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 9055.17241379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 9055.17241379, with a leftover of 2.7e-08.
