We look at the division of 16836021 by 585 
Let's see how many times 585 fits into 16836021.

Step 1:
585 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 585

Advancing to step 2:
16 divided by 585 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 585

On to step 3:
The number 585 fits into 168 0 times, leaving a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Append the next digit (3) from the dividend to 168 and continue with: 1683 / 585

On to step 4:
585 goes into 1683 2 times with a remainder of 513.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1170 from 1683, we get 513.
Grab the next digit (6) from the dividend, add it to 513, then carry on: 5136 / 585

Moving on to step 5:
When dividing 5136 by 585, we get 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 4680 from 5136 and we're left with 456.
Include the next digit (0) from the dividend after 456, then repeat: 4560 / 585

Step 6:
When dividing 4560 by 585, we get 7 with a remainder of 465.
Use 7 as the next digit of our solution. 
Result so far: 287.0
The remainder is 465 after subtracting 4095 from 4560.
Fetch the next digit (2) from the dividend, attach it to 465 and continue: 4652 / 585

On to step 7:
4652 divided by 585 is 7 with a remainder of 557.
Use 7 as the next digit of our solution. 
Result so far: 2877.0
Subtracting 4095 from 4652 leaves us with 557.
Append the next digit (1) from the dividend to 557 and continue with: 5571 / 585

Step 8:
When dividing 5571 by 585, we get 9 with a remainder of 306.
Write down 9 as next digit of the result. 
Result so far: 28779.0
If we subtract 5265 from 5571, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 9:
585 can be fit into 3060 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 28779.5
Subtract 2925 from 3060 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
When dividing 1350 by 585, we get 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 28779.52
If we subtract 1170 from 1350, we get 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 11:
If we divide 1800 by 585, we get 3 and a remainder of 45.
The next digit of our result is 3. 
Result so far: 28779.523
If we take 1755 away from 1800, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
When dividing 450 by 585, we get 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 28779.523
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
When dividing 4500 by 585, we get 7 with a remainder of 405.
Write down 7 as next digit of the result. 
Result so far: 28779.52307
If we take 4095 away from 4500, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 14:
If we divide 4050 by 585, we get 6 and a remainder of 540.
The next digit of our result is 6. 
Result so far: 28779.523076
If we take 3510 away from 4050, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 15:
5400 divided by 585 is 9 with a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 28779.5230769
Subtracting 5265 from 5400 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 16:
585 can be fit into 1350 2 times, resulting in a remainder of 180.
The next digit of our result is 2. 
Result so far: 28779.52307692
Deduct 1170 from 1350 and we're left 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.

The final outcome is 28779.52307692, with a leftover of 1.8e-07.
