We look at the division of 473978 by 51 
We want to divide 473978 by 51.

Going ahead to step 1:
4 divided by 51 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 51

Step 2:
The number 51 fits into 47 0 times, leaving a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 51

Advancing to step 3:
The number 51 fits into 473 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 459 from 473, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 51

Step 4:
The number 51 fits into 149 2 times, leaving a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtracting 102 from 149 leaves us with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 51

Let's proceed to step 5:
477 divided by 51 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 929.0
Subtract 459 from 477 to get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 51

Moving on to step 6:
The number 51 fits into 188 3 times, leaving a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 9293.0
Deduct 153 from 188 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 9293.6
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
51 can be fit into 440 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9293.68
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 9293.686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
140 divided by 51 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 9293.6862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
The number 51 fits into 380 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 9293.68627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
51 goes into 230 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 9293.686274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
51 can be fit into 260 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 9293.6862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
51 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9293.6862745
Subtract 0 from 50 to 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.

The final outcome is 9293.6862745, with a leftover of 5e-08.
