We look at the division of 12573030 by 396 
Our goal is to divide 12573030 by 396.

Let's proceed to step 1:
If we divide 1 by 396, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 396

Advancing to step 2:
396 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 396

On to step 3:
When dividing 125 by 396, we get 0 with a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Append the next digit (7) from the dividend to 125 and continue with: 1257 / 396

Let's proceed to step 4:
The number 396 fits into 1257 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 69 after subtracting 1188 from 1257.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 396

Moving on to step 5:
When dividing 693 by 396, we get 1 with a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 396 from 693 to get 297.
Grab the next digit (0) from the dividend, add it to 297, then carry on: 2970 / 396

Let's proceed to step 6:
396 can be fit into 2970 7 times, resulting in a remainder of 198.
Use 7 as the next digit of our solution. 
Result so far: 317.0
The remainder is 198 after subtracting 2772 from 2970.
Include the next digit (3) from the dividend after 198, then repeat: 1983 / 396

On to step 7:
396 can be fit into 1983 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 3175.0
Subtract 1980 from 1983 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 396

Step 8:
The number 396 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 31750.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
396 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 31750.0
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
If we divide 3000 by 396, we get 7 and a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 31750.07
Subtracting 2772 from 3000 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 11:
2280 divided by 396 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 31750.075
Deduct 1980 from 2280 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
396 can be fit into 3000 7 times, resulting in a remainder of 228.
Use 7 as the next digit of our solution. 
Result so far: 31750.0757
If we take 2772 away from 3000, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 13:
The number 396 fits into 2280 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 31750.07575
If we subtract 1980 from 2280, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
3000 divided by 396 is 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 31750.075757
Subtract 2772 from 3000 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
396 can be fit into 2280 5 times, resulting in a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 31750.0757575
Subtract 1980 from 2280 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
When dividing 3000 by 396, we get 7 with a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 31750.07575757
Subtract 2772 from 3000 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 31750.07575757 and a remainder of 2.28e-07.
