Let's divide 21300666 by 389
Let's see how many times 389 fits into 21300666.

Moving on to step 1:
389 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 389

Going ahead to step 2:
If we divide 21 by 389, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 389

Moving on to step 3:
If we divide 213 by 389, we get 0 and a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Include the next digit (0) from the dividend after 213, then repeat: 2130 / 389

Step 4:
When dividing 2130 by 389, we get 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 1945 from 2130 to get 185.
Take the next digit (0) from the dividend and append it to 185, then repeat: 1850 / 389

Let's proceed to step 5:
1850 divided by 389 is 4 with a remainder of 294.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 1556 from 1850 and we're left with 294.
Include the next digit (6) from the dividend after 294, then repeat: 2946 / 389

On to step 6:
The number 389 fits into 2946 7 times, leaving a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 547.0
Subtract 2723 from 2946 to get 223.
Fetch the next digit (6) from the dividend, attach it to 223 and continue: 2236 / 389

Moving on to step 7:
389 goes into 2236 5 times with a remainder of 291.
Put 5 as the next digit of the answer. 
Result so far: 5475.0
Subtracting 1945 from 2236 leaves us with 291.
Take the next digit (6) from the dividend and append it to 291, then repeat: 2916 / 389

Let's proceed to step 8:
389 goes into 2916 7 times with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 54757.0
If we take 2723 away from 2916, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 9:
1930 divided by 389 is 4 with a remainder of 374.
Write down 4 as next digit of the result. 
Result so far: 54757.4
If we take 1556 away from 1930, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 10:
389 goes into 3740 9 times with a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 54757.49
The remainder is 239 after subtracting 3501 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 11:
389 goes into 2390 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 54757.496
Deduct 2334 from 2390 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 389 fits into 560 1 times, leaving a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 54757.4961
Subtracting 389 from 560 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 13:
If we divide 1710 by 389, we get 4 and a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 54757.49614
If we subtract 1556 from 1710, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 14:
When dividing 1540 by 389, we get 3 with a remainder of 373.
The next digit of our result is 3. 
Result so far: 54757.496143
Subtract 1167 from 1540 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 15:
The number 389 fits into 3730 9 times, leaving a remainder of 229.
Write down 9 as next digit of the result. 
Result so far: 54757.4961439
If we take 3501 away from 3730, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 16:
When dividing 2290 by 389, we get 5 with a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 54757.49614395
Subtract 1945 from 2290 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The quotient of the division is 54757.49614395, and the remainder is 3.45e-07.
