We're dividing 20503157 by 712 
Let's see how many times 712 fits into 20503157.

Let's proceed to step 1:
712 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 712

Let's proceed to step 2:
712 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
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 712

Advancing to step 3:
205 divided by 712 is 0 with a remainder of 205.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 712

Going ahead to step 4:
The number 712 fits into 2050 2 times, leaving a remainder of 626.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1424 from 2050 to get 626.
Include the next digit (3) from the dividend after 626, then repeat: 6263 / 712

Going ahead to step 5:
712 can be fit into 6263 8 times, resulting in a remainder of 567.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 5696 from 6263, we get 567.
Fetch the next digit (1) from the dividend, attach it to 567 and continue: 5671 / 712

Let's proceed to step 6:
712 can be fit into 5671 7 times, resulting in a remainder of 687.
Write down 7 as next digit of the result. 
Result so far: 287.0
If we take 4984 away from 5671, we end up with 687.
Include the next digit (5) from the dividend after 687, then repeat: 6875 / 712

Let's proceed to step 7:
The number 712 fits into 6875 9 times, leaving a remainder of 467.
Write down 9 as next digit of the result. 
Result so far: 2879.0
Subtract 6408 from 6875 to get 467.
Take the next digit (7) from the dividend and append it to 467, then repeat: 4677 / 712

Step 8:
712 can be fit into 4677 6 times, resulting in a remainder of 405.
Put 6 as the next digit of the answer. 
Result so far: 28796.0
Subtracting 4272 from 4677 leaves us 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.

On to step 9:
4050 divided by 712 is 5 with a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 28796.5
The remainder is 490 after subtracting 3560 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
The number 712 fits into 4900 6 times, leaving a remainder of 628.
Record the quotient 6 as the next digit in the result. 
Result so far: 28796.56
Subtract 4272 from 4900 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 11:
6280 divided by 712 is 8 with a remainder of 584.
Record the quotient 8 as the next digit in the result. 
Result so far: 28796.568
Subtract 5696 from 6280 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 12:
5840 divided by 712 is 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 28796.5688
If we subtract 5696 from 5840, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 28796.5688 with a remainder of 0.00144.
