We're dividing 203713 by 51 
We want to divide 203713 by 51.

Going ahead to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 51

Step 2:
20 divided by 51 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 51

Step 3:
The number 51 fits into 203 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 153 from 203 leaves us with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 51

Going ahead to step 4:
The number 51 fits into 507 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 459 from 507 to get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 51

On to step 5:
51 goes into 481 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 399.0
If we take 459 away from 481, we end up with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 51

On to step 6:
51 goes into 223 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 3994.0
Subtract 204 from 223 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 51, we get 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3994.3
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
51 can be fit into 370 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 3994.37
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 3994.372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3994.3725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 3994.37254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3994.372549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
10 divided by 51 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3994.372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 51, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3994.37254901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 3994.37254901 with a remaining 4.9e-08.
