We look at the division of 21885086 by 539 
Our goal is to divide 21885086 by 539.

Advancing to step 1:
2 divided by 539 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 539

Going ahead to step 2:
539 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 539

Step 3:
If we divide 218 by 539, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Take the next digit (8) from the dividend and append it to 218, then repeat: 2188 / 539

Going ahead to step 4:
If we divide 2188 by 539, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2156 from 2188 to get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 539

On to step 5:
If we divide 325 by 539, we get 0 and a remainder of 325.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 325 leaves us with 325.
Include the next digit (0) from the dividend after 325, then repeat: 3250 / 539

Step 6:
3250 divided by 539 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 406.0
Subtract 3234 from 3250 to get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 539

Step 7:
When dividing 168 by 539, we get 0 with a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 4060.0
Deduct 0 from 168 and we're left with 168.
Append the next digit (6) from the dividend to 168 and continue with: 1686 / 539

Let's proceed to step 8:
1686 divided by 539 is 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 40603.0
Subtract 1617 from 1686 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
690 divided by 539 is 1 with a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 40603.1
The remainder is 151 after subtracting 539 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 10:
539 goes into 1510 2 times with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 40603.12
Subtracting 1078 from 1510 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 11:
When dividing 4320 by 539, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 40603.128
Subtract 4312 from 4320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 539, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 40603.128
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
When dividing 800 by 539, we get 1 with a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 40603.12801
If we take 539 away from 800, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 14:
539 can be fit into 2610 4 times, resulting in a remainder of 454.
Record the quotient 4 as the next digit in the result. 
Result so far: 40603.128014
Deduct 2156 from 2610 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 15:
The number 539 fits into 4540 8 times, leaving a remainder of 228.
Record the quotient 8 as the next digit in the result. 
Result so far: 40603.1280148
The remainder is 228 after subtracting 4312 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 16:
539 can be fit into 2280 4 times, resulting in a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 40603.12801484
If we subtract 2156 from 2280, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 40603.12801484 with a remainder of 1.24e-07.
