100304 ÷ 85 
Let's see how many times 85 fits into 100304.

Let's proceed to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 85

Step 2:
85 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 85

Step 3:
100 divided by 85 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 85 from 100 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 85

On to step 4:
When dividing 153 by 85, we get 1 with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 85 from 153 to get 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 85

On to step 5:
If we divide 680 by 85, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 118.0
If we subtract 680 from 680, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 85

On to step 6:
85 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1180.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
85 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 1180.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 85, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1180.04
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
85 goes into 600 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1180.047
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
85 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1180.047
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 85 fits into 500 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1180.04705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 1180.047058
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
85 goes into 700 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 1180.0470588
Subtract 680 from 700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1180.0470588 and a remainder of 2e-07.
