Let's divide 305285 by 51
We want to figure out the number of times 305285 can be divided by 51.

Going ahead to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 51

Let's proceed to step 2:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 51

On to step 3:
305 divided by 51 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 50 after subtracting 255 from 305.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 51

Let's proceed to step 4:
The number 51 fits into 502 9 times, leaving a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtract 459 from 502 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 51

Advancing to step 5:
438 divided by 51 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 598.0
Subtracting 408 from 438 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 51

Going ahead to step 6:
The number 51 fits into 305 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5985.0
If we subtract 255 from 305, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
51 goes into 500 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 5985.9
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
If we divide 410 by 51, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 5985.98
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5985.98
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 5985.9803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
470 divided by 51 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 5985.98039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
110 divided by 51 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5985.980392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 5985.9803921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
290 divided by 51 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5985.98039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 5985.98039215 and a remainder of 3.5e-08.
