We divide 923009 by 87
We're looking to find how many times 87 goes into 923009.

On to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 87

Advancing to step 2:
When dividing 92 by 87, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 87 from 92 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 87

On to step 3:
87 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 87

Going ahead to step 4:
87 goes into 530 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 522 from 530, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 87

Let's proceed to step 5:
If we divide 80 by 87, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 1060.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 87

Going ahead to step 6:
When dividing 809 by 87, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 10609.0
The remainder is 26 after subtracting 783 from 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 87 is 2 with a remainder of 86.
The next digit of our result is 2. 
Result so far: 10609.2
Deduct 174 from 260 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 8:
860 divided by 87 is 9 with a remainder of 77.
The next digit of our result is 9. 
Result so far: 10609.29
Subtract 783 from 860 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
87 goes into 770 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 10609.298
If we take 696 away from 770, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
If we divide 740 by 87, we get 8 and a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 10609.2988
Subtract 696 from 740 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 10609.2988, and the remainder is 0.00044.
