We look at the division of 20505423 by 731 
Let's see how many times 731 fits into 20505423.

Going ahead to step 1:
If we divide 2 by 731, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 731

Let's proceed to step 2:
731 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 731

Moving on to step 3:
731 can be fit into 205 0 times, resulting in a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 731

Step 4:
If we divide 2050 by 731, we get 2 and a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1462 from 2050 to get 588.
Bring next digit (5) of the dividend behind the 588 and repeat the process: 5885 / 731

Advancing to step 5:
5885 divided by 731 is 8 with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 5848 from 5885 to get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 731

Moving on to step 6:
731 goes into 374 0 times with a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 280.0
If we subtract 0 from 374, we get 374.
Take the next digit (2) from the dividend and append it to 374, then repeat: 3742 / 731

On to step 7:
If we divide 3742 by 731, we get 5 and a remainder of 87.
Use 5 as the next digit of our solution. 
Result so far: 2805.0
Deduct 3655 from 3742 and we're left with 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 731

Moving on to step 8:
When dividing 873 by 731, we get 1 with a remainder of 142.
The next digit of our result is 1. 
Result so far: 28051.0
If we take 731 away from 873, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
If we divide 1420 by 731, we get 1 and a remainder of 689.
Write down 1 as next digit of the result. 
Result so far: 28051.1
Subtract 731 from 1420 to get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 10:
6890 divided by 731 is 9 with a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 28051.19
If we subtract 6579 from 6890, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 11:
731 can be fit into 3110 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 28051.194
The remainder is 186 after subtracting 2924 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 12:
731 can be fit into 1860 2 times, resulting in a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 28051.1942
Subtract 1462 from 1860 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 13:
The number 731 fits into 3980 5 times, leaving a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 28051.19425
Subtracting 3655 from 3980 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 14:
731 can be fit into 3250 4 times, resulting in a remainder of 326.
Record the quotient 4 as the next digit in the result. 
Result so far: 28051.194254
Subtracting 2924 from 3250 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 15:
731 can be fit into 3260 4 times, resulting in a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 28051.1942544
If we take 2924 away from 3260, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 28051.1942544 with a remainder of 3.36e-06.
