Let's divide 86015425 by 804
Our goal is to divide 86015425 by 804.

Step 1:
The number 804 fits into 8 0 times, leaving 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 (6) from the dividend to 8 and continue with: 86 / 804

Let's proceed to step 2:
804 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 804

Moving on to step 3:
860 divided by 804 is 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 804 from 860 leaves us with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 804

Step 4:
If we divide 561 by 804, we get 0 and a remainder of 561.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 561 after subtracting 0 from 561.
Append the next digit (5) from the dividend to 561 and continue with: 5615 / 804

Let's proceed to step 5:
When dividing 5615 by 804, we get 6 with a remainder of 791.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 4824 from 5615, we get 791.
Include the next digit (4) from the dividend after 791, then repeat: 7914 / 804

Advancing to step 6:
804 can be fit into 7914 9 times, resulting in a remainder of 678.
Put 9 as the next digit of the answer. 
Result so far: 1069.0
If we subtract 7236 from 7914, we get 678.
Grab the next digit (2) from the dividend, add it to 678, then carry on: 6782 / 804

Going ahead to step 7:
The number 804 fits into 6782 8 times, leaving a remainder of 350.
Write down 8 as next digit of the result. 
Result so far: 10698.0
Subtract 6432 from 6782 to get 350.
Include the next digit (5) from the dividend after 350, then repeat: 3505 / 804

Step 8:
The number 804 fits into 3505 4 times, leaving a remainder of 289.
Use 4 as the next digit of our solution. 
Result so far: 106984.0
If we take 3216 away from 3505, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
804 can be fit into 2890 3 times, resulting in a remainder of 478.
The number 3 becomes the next digit in our result. 
Result so far: 106984.3
If we take 2412 away from 2890, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 10:
804 goes into 4780 5 times with a remainder of 760.
Write down 5 as next digit of the result. 
Result so far: 106984.35
The remainder is 760 after subtracting 4020 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 11:
804 can be fit into 7600 9 times, resulting in a remainder of 364.
Record the quotient 9 as the next digit in the result. 
Result so far: 106984.359
Deduct 7236 from 7600 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 12:
When dividing 3640 by 804, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 106984.3594
Subtract 3216 from 3640 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 13:
804 can be fit into 4240 5 times, resulting in a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 106984.35945
If we subtract 4020 from 4240, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
804 goes into 2200 2 times with a remainder of 592.
Put 2 as the next digit of the answer. 
Result so far: 106984.359452
Subtracting 1608 from 2200 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 15:
804 can be fit into 5920 7 times, resulting in a remainder of 292.
The next digit of our result is 7. 
Result so far: 106984.3594527
Deduct 5628 from 5920 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 16:
2920 divided by 804 is 3 with a remainder of 508.
Write down 3 as next digit of the result. 
Result so far: 106984.35945273
The remainder is 508 after subtracting 2412 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

In conclusion, the division gives 106984.35945273 with a balance of 5.08e-07.
