We're dividing 87004035 by 439 
We want to figure out the number of times 87004035 can be divided by 439.

Going ahead to step 1:
8 divided by 439 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 439

On to step 2:
87 divided by 439 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 439

Going ahead to step 3:
When dividing 870 by 439, we get 1 with a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 431 after subtracting 439 from 870.
Take the next digit (0) from the dividend and append it to 431, then repeat: 4310 / 439

Advancing to step 4:
The number 439 fits into 4310 9 times, leaving a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 3951 from 4310 leaves us with 359.
Include the next digit (4) from the dividend after 359, then repeat: 3594 / 439

Going ahead to step 5:
The number 439 fits into 3594 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 198.0
If we take 3512 away from 3594, we end up with 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 439

Step 6:
The number 439 fits into 820 1 times, leaving a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 1981.0
Deduct 439 from 820 and we're left with 381.
Grab the next digit (3) from the dividend, add it to 381, then carry on: 3813 / 439

Going ahead to step 7:
If we divide 3813 by 439, we get 8 and a remainder of 301.
Use 8 as the next digit of our solution. 
Result so far: 19818.0
If we take 3512 away from 3813, we end up with 301.
Include the next digit (5) from the dividend after 301, then repeat: 3015 / 439

Going ahead to step 8:
The number 439 fits into 3015 6 times, leaving a remainder of 381.
The number 6 becomes the next digit in our result. 
Result so far: 198186.0
Subtract 2634 from 3015 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
439 can be fit into 3810 8 times, resulting in a remainder of 298.
Write down 8 as next digit of the result. 
Result so far: 198186.8
Deduct 3512 from 3810 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 10:
2980 divided by 439 is 6 with a remainder of 346.
Use 6 as the next digit of our solution. 
Result so far: 198186.86
If we take 2634 away from 2980, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 11:
439 can be fit into 3460 7 times, resulting in a remainder of 387.
The next digit of our result is 7. 
Result so far: 198186.867
Subtract 3073 from 3460 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 12:
The number 439 fits into 3870 8 times, leaving a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 198186.8678
Subtract 3512 from 3870 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
If we divide 3580 by 439, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 198186.86788
If we subtract 3512 from 3580, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 198186.86788, with a leftover of 6.8e-05.
