396371 divided by 51 
We're looking to find how many times 51 goes into 396371.

Let's proceed to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 51

Going ahead to step 2:
51 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 51

On to step 3:
51 can be fit into 396 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 357 away from 396, we end up with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 51

Step 4:
51 can be fit into 393 7 times, resulting in a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 357 from 393, we get 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 51

Advancing to step 5:
367 divided by 51 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 777.0
If we subtract 357 from 367, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 51

Step 6:
The number 51 fits into 101 1 times, leaving a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 7771.0
Subtract 51 from 101 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.

Step 7:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 7771.9
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
When dividing 410 by 51, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 7771.98
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
51 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7771.98
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 51 fits into 200 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7771.9803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
If we divide 470 by 51, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 7771.98039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 51, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7771.980392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 51 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 7771.9803921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 14:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 7771.98039215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 7771.98039215 with a remaining 3.5e-08.
