We look at the division of 87005493 by 104 
We want to figure out the number of times 87005493 can be divided by 104.

On to step 1:
If we divide 8 by 104, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 104

Step 2:
If we divide 87 by 104, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 104

Let's proceed to step 3:
104 can be fit into 870 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 832 from 870 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 104

On to step 4:
When dividing 380 by 104, we get 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Deduct 312 from 380 and we're left with 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 104

On to step 5:
If we divide 685 by 104, we get 6 and a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 836.0
If we subtract 624 from 685, we get 61.
Fetch the next digit (4) from the dividend, attach it to 61 and continue: 614 / 104

Moving on to step 6:
614 divided by 104 is 5 with a remainder of 94.
Put 5 as the next digit of the answer. 
Result so far: 8365.0
If we subtract 520 from 614, we get 94.
Take the next digit (9) from the dividend and append it to 94, then repeat: 949 / 104

On to step 7:
If we divide 949 by 104, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 83659.0
If we take 936 away from 949, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 104

On to step 8:
When dividing 133 by 104, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 836591.0
Subtracting 104 from 133 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
104 can be fit into 290 2 times, resulting in a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 836591.2
Subtract 208 from 290 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
If we divide 820 by 104, we get 7 and a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 836591.27
If we subtract 728 from 820, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
If we divide 920 by 104, we get 8 and a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 836591.278
Subtract 832 from 920 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
When dividing 880 by 104, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 836591.2788
Subtract 832 from 880 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 836591.2788 with a remaining 0.00048.
