We're dividing 85809985 by 204 
Let's see how many times 204 fits into 85809985.

On to step 1:
If we divide 8 by 204, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 204

Advancing to step 2:
204 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 204

Step 3:
If we divide 858 by 204, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 816 from 858, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 204

On to step 4:
The number 204 fits into 420 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 408 from 420, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 204

Advancing to step 5:
204 can be fit into 129 0 times, resulting in a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we subtract 0 from 129, we get 129.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 204

Advancing to step 6:
1299 divided by 204 is 6 with a remainder of 75.
Record the quotient 6 as the next digit in the result. 
Result so far: 4206.0
Subtract 1224 from 1299 to get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 204

Let's proceed to step 7:
204 can be fit into 758 3 times, resulting in a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 42063.0
If we take 612 away from 758, we end up with 146.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 204

Moving on to step 8:
204 goes into 1465 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 420637.0
If we take 1428 away from 1465, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
204 goes into 370 1 times with a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 420637.1
Deduct 204 from 370 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
204 goes into 1660 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 420637.18
If we subtract 1632 from 1660, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
204 can be fit into 280 1 times, resulting in a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 420637.181
Subtract 204 from 280 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
204 goes into 760 3 times with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 420637.1813
Deduct 612 from 760 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 13:
204 goes into 1480 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 420637.18137
The remainder is 52 after subtracting 1428 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
204 goes into 520 2 times with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 420637.181372
If we take 408 away from 520, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
The number 204 fits into 1120 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 420637.1813725
The remainder is 100 after subtracting 1020 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
204 can be fit into 1000 4 times, resulting in a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 420637.18137254
The remainder is 184 after subtracting 816 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

After the division, we end up with 420637.18137254 and a remainder of 1.84e-07.
