We're dividing 20460309 by 966 
We want to divide 20460309 by 966.

Step 1:
The number 966 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 966

Advancing to step 2:
966 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 966

On to step 3:
The number 966 fits into 204 0 times, leaving a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Bring next digit (6) of the dividend behind the 204 and repeat the process: 2046 / 966

Let's proceed to step 4:
966 can be fit into 2046 2 times, resulting in a remainder of 114.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1932 from 2046, we get 114.
Append the next digit (0) from the dividend to 114 and continue with: 1140 / 966

On to step 5:
966 can be fit into 1140 1 times, resulting in a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 966 from 1140 to get 174.
Grab the next digit (3) from the dividend, add it to 174, then carry on: 1743 / 966

Going ahead to step 6:
1743 divided by 966 is 1 with a remainder of 777.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtracting 966 from 1743 leaves us with 777.
Grab the next digit (0) from the dividend, add it to 777, then carry on: 7770 / 966

Step 7:
When dividing 7770 by 966, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 2118.0
Subtracting 7728 from 7770 leaves us with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 966

Step 8:
429 divided by 966 is 0 with a remainder of 429.
Use 0 as the next digit of our solution. 
Result so far: 21180.0
The remainder is 429 after subtracting 0 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 9:
966 goes into 4290 4 times with a remainder of 426.
Record the quotient 4 as the next digit in the result. 
Result so far: 21180.4
If we take 3864 away from 4290, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 10:
The number 966 fits into 4260 4 times, leaving a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 21180.44
If we subtract 3864 from 4260, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Our division results in 21180.44 with a remaining 0.396.
