We divide 978030 by 51
We want to figure out the number of times 978030 can be divided by 51.

Step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 51

Moving on to step 2:
51 goes into 97 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 97, we get 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 51

Moving on to step 3:
When dividing 468 by 51, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 459 from 468 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 51

Moving on to step 4:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 191.0
Subtract 51 from 90 to get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 51

Let's proceed to step 5:
When dividing 393 by 51, we get 7 with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 1917.0
If we take 357 away from 393, we end up with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 51

On to step 6:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 19177.0
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
51 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 19177.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 51 fits into 300 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 19177.05
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 19177.058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 19177.0588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 19177.0588 with a remaining 0.00012.
