We look at the division of 978972 by 51 
Let's see how many times 51 fits into 978972.

Let's proceed to step 1:
9 divided by 51 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 51

On to step 2:
97 divided by 51 is 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 97 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 51

Let's proceed to step 3:
468 divided by 51 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 459 away from 468, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 51

Moving on to step 4:
51 goes into 99 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtract 51 from 99 to get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 51

Advancing to step 5:
The number 51 fits into 487 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1919.0
Deduct 459 from 487 and we're left with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 51

Let's proceed to step 6:
If we divide 282 by 51, we get 5 and a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 19195.0
If we subtract 255 from 282, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 51 fits into 270 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 19195.5
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
51 can be fit into 150 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 19195.52
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
If we divide 480 by 51, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 19195.529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
If we divide 210 by 51, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 19195.5294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 19195.52941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 19195.529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 19195.529411, and the remainder is 3.9e-06.
