We look at the division of 307122 by 51 
Our goal is to divide 307122 by 51.

Going ahead to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 51

Moving on to step 2:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 51

Going ahead to step 3:
51 can be fit into 307 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 306 away from 307, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 51

Going ahead to step 4:
If we divide 11 by 51, we get 0 and a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 51

Step 5:
When dividing 112 by 51, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 602.0
Subtract 102 from 112 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 51

Going ahead to step 6:
51 goes into 102 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 6022.0
Subtracting 102 from 102 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
51 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6022.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 51 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6022.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6022.0 and a remainder of 0.0.
