21299780 divided by 66 
Our goal is to divide 21299780 by 66.

Step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 66

Going ahead to step 2:
When dividing 21 by 66, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 66

Going ahead to step 3:
212 divided by 66 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 14 after subtracting 198 from 212.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 66

Advancing to step 4:
The number 66 fits into 149 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 132 away from 149, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 66

Advancing to step 5:
If we divide 179 by 66, we get 2 and a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
Deduct 132 from 179 and we're left with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 66

Moving on to step 6:
If we divide 477 by 66, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3227.0
Deduct 462 from 477 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 66

Moving on to step 7:
If we divide 158 by 66, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 32272.0
If we subtract 132 from 158, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 66

Going ahead to step 8:
When dividing 260 by 66, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 322723.0
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
When dividing 620 by 66, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 322723.9
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
66 goes into 260 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 322723.93
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
620 divided by 66 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 322723.939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 322723.9393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
66 goes into 620 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 322723.93939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 322723.939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 15:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 322723.9393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 16:
When dividing 260 by 66, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 322723.93939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.
