We look at the division of 203764 by 51 
We're looking to find how many times 51 goes into 203764.

Going ahead to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 51

Moving on to step 2:
51 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 51

Let's proceed to step 3:
If we divide 203 by 51, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 153 from 203 leaves us with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 51

Let's proceed to step 4:
If we divide 507 by 51, we get 9 and a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 459 from 507 leaves us with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 51

On to step 5:
The number 51 fits into 486 9 times, leaving a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
The remainder is 27 after subtracting 459 from 486.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 51

Advancing to step 6:
274 divided by 51 is 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 3995.0
If we subtract 255 from 274, we 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.

Let's proceed to step 7:
190 divided by 51 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 3995.3
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:
When dividing 370 by 51, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3995.37
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 51, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3995.372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
280 divided by 51 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3995.3725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 3995.37254
If we subtract 204 from 250, we 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.

Advancing to step 12:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3995.372549
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.

Let's proceed to step 13:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3995.372549
Deduct 0 from 10 and we're left 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.

Step 14:
51 can be fit into 100 1 times, resulting in a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 3995.37254901
If we subtract 51 from 100, we 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.

After the division, we end up with 3995.37254901 and a remainder of 4.9e-08.
