We look at the division of 20183589 by 204 
We're looking to find how many times 204 goes into 20183589.

On to step 1:
If we divide 2 by 204, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 204

Step 2:
204 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 204

Step 3:
201 divided by 204 is 0 with a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 201, we end up with 201.
Grab the next digit (8) from the dividend, add it to 201, then carry on: 2018 / 204

Going ahead to step 4:
204 goes into 2018 9 times with a remainder of 182.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 182 after subtracting 1836 from 2018.
Include the next digit (3) from the dividend after 182, then repeat: 1823 / 204

Moving on to step 5:
204 can be fit into 1823 8 times, resulting in a remainder of 191.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Deduct 1632 from 1823 and we're left with 191.
Bring next digit (5) of the dividend behind the 191 and repeat the process: 1915 / 204

Advancing to step 6:
204 can be fit into 1915 9 times, resulting in a remainder of 79.
The next digit of our result is 9. 
Result so far: 989.0
Subtracting 1836 from 1915 leaves us with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 204

Step 7:
If we divide 798 by 204, we get 3 and a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 9893.0
If we subtract 612 from 798, we get 186.
Append the next digit (9) from the dividend to 186 and continue with: 1869 / 204

On to step 8:
204 goes into 1869 9 times with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 98939.0
Subtract 1836 from 1869 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
204 can be fit into 330 1 times, resulting in a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 98939.1
Subtracting 204 from 330 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
204 goes into 1260 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 98939.16
Subtract 1224 from 1260 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 204, we get 1 with a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 98939.161
If we take 204 away from 360, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
When dividing 1560 by 204, we get 7 with a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 98939.1617
Subtract 1428 from 1560 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 13:
The number 204 fits into 1320 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 98939.16176
Deduct 1224 from 1320 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
960 divided by 204 is 4 with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 98939.161764
Deduct 816 from 960 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 15:
When dividing 1440 by 204, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 98939.1617647
The remainder is 12 after subtracting 1428 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
The number 204 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 98939.1617647
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 98939.1617647 with a remaining 1.2e-07.
