We look at the division of 20519455 by 744 
Our goal is to divide 20519455 by 744.

Going ahead to step 1:
2 divided by 744 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 744

Going ahead to step 2:
744 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
The remainder is 20 after subtracting 0 from 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 744

On to step 3:
If we divide 205 by 744, we get 0 and a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Bring next digit (1) of the dividend behind the 205 and repeat the process: 2051 / 744

Advancing to step 4:
744 can be fit into 2051 2 times, resulting in a remainder of 563.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1488 from 2051 leaves us with 563.
Bring next digit (9) of the dividend behind the 563 and repeat the process: 5639 / 744

Step 5:
5639 divided by 744 is 7 with a remainder of 431.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 5208 from 5639 leaves us with 431.
Include the next digit (4) from the dividend after 431, then repeat: 4314 / 744

Let's proceed to step 6:
744 can be fit into 4314 5 times, resulting in a remainder of 594.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.0
Subtracting 3720 from 4314 leaves us with 594.
Append the next digit (5) from the dividend to 594 and continue with: 5945 / 744

Advancing to step 7:
5945 divided by 744 is 7 with a remainder of 737.
Use 7 as the next digit of our solution. 
Result so far: 2757.0
Deduct 5208 from 5945 and we're left with 737.
Include the next digit (5) from the dividend after 737, then repeat: 7375 / 744

Let's proceed to step 8:
When dividing 7375 by 744, we get 9 with a remainder of 679.
Use 9 as the next digit of our solution. 
Result so far: 27579.0
If we take 6696 away from 7375, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Going ahead to step 9:
6790 divided by 744 is 9 with a remainder of 94.
Record the quotient 9 as the next digit in the result. 
Result so far: 27579.9
The remainder is 94 after subtracting 6696 from 6790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
744 goes into 940 1 times with a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 27579.91
Subtracting 744 from 940 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
If we divide 1960 by 744, we get 2 and a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 27579.912
If we subtract 1488 from 1960, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 12:
When dividing 4720 by 744, we get 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 27579.9126
The remainder is 256 after subtracting 4464 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
If we divide 2560 by 744, we get 3 and a remainder of 328.
The number 3 becomes the next digit in our result. 
Result so far: 27579.91263
Subtract 2232 from 2560 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 14:
If we divide 3280 by 744, we get 4 and a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 27579.912634
Subtracting 2976 from 3280 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
744 can be fit into 3040 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 27579.9126344
If we subtract 2976 from 3040, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 27579.9126344 and a remainder of 6.4e-07.
