We're dividing 20943589 by 966 
We want to divide 20943589 by 966.

Going ahead to step 1:
If we divide 2 by 966, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 966

Step 2:
If we divide 20 by 966, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 966

On to step 3:
The number 966 fits into 209 0 times, leaving a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (4) from the dividend, add it to 209, then carry on: 2094 / 966

Moving on to step 4:
2094 divided by 966 is 2 with a remainder of 162.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1932 from 2094 and we're left with 162.
Bring next digit (3) of the dividend behind the 162 and repeat the process: 1623 / 966

Advancing to step 5:
966 goes into 1623 1 times with a remainder of 657.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 657 after subtracting 966 from 1623.
Take the next digit (5) from the dividend and append it to 657, then repeat: 6575 / 966

Going ahead to step 6:
The number 966 fits into 6575 6 times, leaving a remainder of 779.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we take 5796 away from 6575, we end up with 779.
Grab the next digit (8) from the dividend, add it to 779, then carry on: 7798 / 966

Step 7:
If we divide 7798 by 966, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 2168.0
Subtract 7728 from 7798 to get 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 966

Let's proceed to step 8:
When dividing 709 by 966, we get 0 with a remainder of 709.
The number 0 becomes the next digit in our result. 
Result so far: 21680.0
Subtract 0 from 709 to get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 9:
If we divide 7090 by 966, we get 7 and a remainder of 328.
Write down 7 as next digit of the result. 
Result so far: 21680.7
Deduct 6762 from 7090 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
The number 966 fits into 3280 3 times, leaving a remainder of 382.
Use 3 as the next digit of our solution. 
Result so far: 21680.73
Subtract 2898 from 3280 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 11:
When dividing 3820 by 966, we get 3 with a remainder of 922.
Use 3 as the next digit of our solution. 
Result so far: 21680.733
The remainder is 922 after subtracting 2898 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

The quotient of the division is 21680.733, and the remainder is 0.0922.
