We're dividing 51182803 by 396 
We want to figure out the number of times 51182803 can be divided by 396.

Going ahead to step 1:
When dividing 5 by 396, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 396

On to step 2:
When dividing 51 by 396, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 396

Let's proceed to step 3:
When dividing 511 by 396, we get 1 with a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 396 away from 511, we end up with 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 396

Moving on to step 4:
1158 divided by 396 is 2 with a remainder of 366.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 366 after subtracting 792 from 1158.
Take the next digit (2) from the dividend and append it to 366, then repeat: 3662 / 396

Advancing to step 5:
396 can be fit into 3662 9 times, resulting in a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we subtract 3564 from 3662, we get 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 396

On to step 6:
When dividing 988 by 396, we get 2 with a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 1292.0
Subtract 792 from 988 to get 196.
Append the next digit (0) from the dividend to 196 and continue with: 1960 / 396

Let's proceed to step 7:
If we divide 1960 by 396, we get 4 and a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 12924.0
Deduct 1584 from 1960 and we're left with 376.
Append the next digit (3) from the dividend to 376 and continue with: 3763 / 396

Let's proceed to step 8:
If we divide 3763 by 396, we get 9 and a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 129249.0
Subtract 3564 from 3763 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 9:
The number 396 fits into 1990 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 129249.5
Subtracting 1980 from 1990 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
396 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 129249.5
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
396 can be fit into 1000 2 times, resulting in a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 129249.502
Subtract 792 from 1000 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 12:
When dividing 2080 by 396, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 129249.5025
Deduct 1980 from 2080 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
If we divide 1000 by 396, we get 2 and a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 129249.50252
Deduct 792 from 1000 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 14:
If we divide 2080 by 396, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 129249.502525
If we subtract 1980 from 2080, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
If we divide 1000 by 396, we get 2 and a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 129249.5025252
Subtracting 792 from 1000 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
When dividing 2080 by 396, we get 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 129249.50252525
If we subtract 1980 from 2080, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 129249.50252525, with a leftover of 1e-07.
