We look at the division of 20539758 by 671 
We want to divide 20539758 by 671.

Advancing to step 1:
2 divided by 671 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 671

Step 2:
If we divide 20 by 671, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 671

Step 3:
The number 671 fits into 205 0 times, leaving a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Grab the next digit (3) from the dividend, add it to 205, then carry on: 2053 / 671

Step 4:
When dividing 2053 by 671, we get 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2013 from 2053 leaves us with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 671

Going ahead to step 5:
671 goes into 409 0 times with a remainder of 409.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 409, we get 409.
Take the next digit (7) from the dividend and append it to 409, then repeat: 4097 / 671

Step 6:
If we divide 4097 by 671, we get 6 and a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 306.0
Subtracting 4026 from 4097 leaves us with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 671

Let's proceed to step 7:
If we divide 715 by 671, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 3061.0
If we subtract 671 from 715, we get 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 671

Going ahead to step 8:
When dividing 448 by 671, we get 0 with a remainder of 448.
Use 0 as the next digit of our solution. 
Result so far: 30610.0
If we subtract 0 from 448, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 9:
When dividing 4480 by 671, we get 6 with a remainder of 454.
Put 6 as the next digit of the answer. 
Result so far: 30610.6
Deduct 4026 from 4480 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 10:
The number 671 fits into 4540 6 times, leaving a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 30610.66
If we subtract 4026 from 4540, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Our division results in 30610.66 with a remaining 0.514.
