We look at the division of 91420170 by 204 
Let's see how many times 204 fits into 91420170.

On to step 1:
9 divided by 204 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 204

Step 2:
204 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 204

Let's proceed to step 3:
204 can be fit into 914 4 times, resulting in a remainder of 98.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 816 from 914, we get 98.
Include the next digit (2) from the dividend after 98, then repeat: 982 / 204

Moving on to step 4:
204 goes into 982 4 times with a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 44.0
The remainder is 166 after subtracting 816 from 982.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 204

On to step 5:
204 can be fit into 1660 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 448.0
Deduct 1632 from 1660 and we're left with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 204

Going ahead to step 6:
If we divide 281 by 204, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 4481.0
The remainder is 77 after subtracting 204 from 281.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 204

On to step 7:
When dividing 777 by 204, we get 3 with a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 44813.0
Subtracting 612 from 777 leaves us with 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 204

Step 8:
204 can be fit into 1650 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 448138.0
Deduct 1632 from 1650 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 204 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 448138.0
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
1800 divided by 204 is 8 with a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 448138.08
The remainder is 168 after subtracting 1632 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
204 goes into 1680 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 448138.088
If we take 1632 away from 1680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 448138.088, and the remainder is 0.0048.
