We look at the division of 12496538 by 966 
Our goal is to divide 12496538 by 966.

Step 1:
The number 966 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 966

Advancing to step 2:
966 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 966

Step 3:
124 divided by 966 is 0 with a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 966

Going ahead to step 4:
The number 966 fits into 1249 1 times, leaving a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 966 from 1249, we get 283.
Grab the next digit (6) from the dividend, add it to 283, then carry on: 2836 / 966

Moving on to step 5:
When dividing 2836 by 966, we get 2 with a remainder of 904.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 904 after subtracting 1932 from 2836.
Bring next digit (5) of the dividend behind the 904 and repeat the process: 9045 / 966

Moving on to step 6:
If we divide 9045 by 966, we get 9 and a remainder of 351.
The next digit of our result is 9. 
Result so far: 129.0
If we subtract 8694 from 9045, we get 351.
Take the next digit (3) from the dividend and append it to 351, then repeat: 3513 / 966

Step 7:
When dividing 3513 by 966, we get 3 with a remainder of 615.
The next digit of our result is 3. 
Result so far: 1293.0
If we subtract 2898 from 3513, we get 615.
Grab the next digit (8) from the dividend, add it to 615, then carry on: 6158 / 966

Step 8:
The number 966 fits into 6158 6 times, leaving a remainder of 362.
The next digit of our result is 6. 
Result so far: 12936.0
Subtract 5796 from 6158 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
966 can be fit into 3620 3 times, resulting in a remainder of 722.
Write down 3 as next digit of the result. 
Result so far: 12936.3
Subtract 2898 from 3620 to get 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

On to step 10:
966 goes into 7220 7 times with a remainder of 458.
Write down 7 as next digit of the result. 
Result so far: 12936.37
If we take 6762 away from 7220, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 11:
If we divide 4580 by 966, we get 4 and a remainder of 716.
The number 4 becomes the next digit in our result. 
Result so far: 12936.374
Subtract 3864 from 4580 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 12:
966 can be fit into 7160 7 times, resulting in a remainder of 398.
The next digit of our result is 7. 
Result so far: 12936.3747
Deduct 6762 from 7160 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 13:
966 can be fit into 3980 4 times, resulting in a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 12936.37474
If we subtract 3864 from 3980, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
The number 966 fits into 1160 1 times, leaving a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 12936.374741
Subtracting 966 from 1160 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 15:
The number 966 fits into 1940 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12936.3747412
The remainder is 8 after subtracting 1932 from 1940.
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 16:
The number 966 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 12936.3747412
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 12936.3747412, and the remainder is 8e-08.
