51152179 ÷ 393 
Our goal is to divide 51152179 by 393.

Step 1:
5 divided by 393 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 393

On to step 2:
51 divided by 393 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 393

Advancing to step 3:
393 goes into 511 1 times with a remainder of 118.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 393 from 511 to get 118.
Include the next digit (5) from the dividend after 118, then repeat: 1185 / 393

On to step 4:
When dividing 1185 by 393, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1179 from 1185 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 393

Let's proceed to step 5:
When dividing 62 by 393, we get 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 130.0
If we take 0 away from 62, we end up with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 393

Moving on to step 6:
When dividing 621 by 393, we get 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1301.0
If we subtract 393 from 621, we get 228.
Take the next digit (7) from the dividend and append it to 228, then repeat: 2287 / 393

Moving on to step 7:
The number 393 fits into 2287 5 times, leaving a remainder of 322.
Put 5 as the next digit of the answer. 
Result so far: 13015.0
If we subtract 1965 from 2287, we get 322.
Include the next digit (9) from the dividend after 322, then repeat: 3229 / 393

Step 8:
The number 393 fits into 3229 8 times, leaving a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 130158.0
If we take 3144 away from 3229, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
If we divide 850 by 393, we get 2 and a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 130158.2
Deduct 786 from 850 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
393 can be fit into 640 1 times, resulting in a remainder of 247.
Write down 1 as next digit of the result. 
Result so far: 130158.21
Subtracting 393 from 640 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 11:
The number 393 fits into 2470 6 times, leaving a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 130158.216
If we subtract 2358 from 2470, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
If we divide 1120 by 393, we get 2 and a remainder of 334.
The next digit of our result is 2. 
Result so far: 130158.2162
The remainder is 334 after subtracting 786 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 13:
393 can be fit into 3340 8 times, resulting in a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 130158.21628
Deduct 3144 from 3340 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 14:
393 can be fit into 1960 4 times, resulting in a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 130158.216284
Deduct 1572 from 1960 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 15:
If we divide 3880 by 393, we get 9 and a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 130158.2162849
Subtracting 3537 from 3880 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 16:
When dividing 3430 by 393, we get 8 with a remainder of 286.
The number 8 becomes the next digit in our result. 
Result so far: 130158.21628498
If we subtract 3144 from 3430, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

In conclusion, the division gives 130158.21628498 with a balance of 2.86e-07.
