We look at the division of 51055 by 30 
We want to divide 51055 by 30.

Moving on to step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 30

On to step 2:
The number 30 fits into 51 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 30 from 51 leaves us with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 30

Step 3:
If we divide 210 by 30, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 210 from 210, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 30

Going ahead to step 4:
The number 30 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Advancing to step 5:
30 goes into 55 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
If we take 30 away from 55, 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.

Going ahead to step 6:
When dividing 250 by 30, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1701.8
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 1701.83
Subtracting 90 from 100 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.

Step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 1701.833
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 1701.833 with a balance of 0.001.
