392127 divided by 51 
We're looking to find how many times 51 goes into 392127.

Step 1:
3 divided by 51 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
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

Moving on to step 2:
If we divide 39 by 51, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 51

Going ahead to step 3:
If we divide 392 by 51, we get 7 and a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 357 away from 392, we end up with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 51

Step 4:
When dividing 351 by 51, we get 6 with a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 45 after subtracting 306 from 351.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 51

Moving on to step 5:
When dividing 452 by 51, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 768.0
The remainder is 44 after subtracting 408 from 452.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 51

Moving on to step 6:
51 goes into 447 8 times with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 7688.0
If we take 408 away from 447, we end up 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.

Advancing to step 7:
When dividing 390 by 51, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 7688.7
If we subtract 357 from 390, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
330 divided by 51 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7688.76
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
51 goes into 240 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 7688.764
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
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: 7688.7647
If we subtract 357 from 360, we 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.

Step 11:
51 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7688.7647
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 51 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 7688.764705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 7688.7647058
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 14:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 7688.76470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 7688.76470588, with a leftover of 1.2e-08.
