We're dividing 20138491 by 549 
We want to divide 20138491 by 549.

Moving on to step 1:
2 divided by 549 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 549

Step 2:
When dividing 20 by 549, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 549

Advancing to step 3:
If we divide 201 by 549, we get 0 and a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Grab the next digit (3) from the dividend, add it to 201, then carry on: 2013 / 549

Let's proceed to step 4:
When dividing 2013 by 549, we get 3 with a remainder of 366.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1647 from 2013, we get 366.
Bring next digit (8) of the dividend behind the 366 and repeat the process: 3668 / 549

Step 5:
When dividing 3668 by 549, we get 6 with a remainder of 374.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 3294 away from 3668, we end up with 374.
Include the next digit (4) from the dividend after 374, then repeat: 3744 / 549

On to step 6:
549 goes into 3744 6 times with a remainder of 450.
The next digit of our result is 6. 
Result so far: 366.0
If we subtract 3294 from 3744, we get 450.
Fetch the next digit (9) from the dividend, attach it to 450 and continue: 4509 / 549

Going ahead to step 7:
549 goes into 4509 8 times with a remainder of 117.
The next digit of our result is 8. 
Result so far: 3668.0
Deduct 4392 from 4509 and we're left with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 549

Let's proceed to step 8:
When dividing 1171 by 549, we get 2 with a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 36682.0
Subtracting 1098 from 1171 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
The number 549 fits into 730 1 times, leaving a remainder of 181.
The next digit of our result is 1. 
Result so far: 36682.1
If we subtract 549 from 730, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 10:
The number 549 fits into 1810 3 times, leaving a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 36682.13
If we take 1647 away from 1810, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 11:
If we divide 1630 by 549, we get 2 and a remainder of 532.
The number 2 becomes the next digit in our result. 
Result so far: 36682.132
If we take 1098 away from 1630, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 12:
5320 divided by 549 is 9 with a remainder of 379.
Write down 9 as next digit of the result. 
Result so far: 36682.1329
If we take 4941 away from 5320, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 13:
When dividing 3790 by 549, we get 6 with a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 36682.13296
Subtracting 3294 from 3790 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 14:
The number 549 fits into 4960 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 36682.132969
Subtracting 4941 from 4960 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 15:
If we divide 190 by 549, we get 0 and a remainder of 190.
The next digit of our result is 0. 
Result so far: 36682.132969
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 16:
The number 549 fits into 1900 3 times, leaving a remainder of 253.
The next digit of our result is 3. 
Result so far: 36682.13296903
Subtract 1647 from 1900 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

The final result is 36682.13296903 with a remainder of 2.53e-07.
