We look at the division of 21749713 by 66 
Our goal is to divide 21749713 by 66.

On to step 1:
2 divided by 66 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 66

On to step 2:
When dividing 21 by 66, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 66

Advancing to step 3:
66 goes into 217 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 19 after subtracting 198 from 217.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 66

Step 4:
66 can be fit into 194 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 132 from 194 and we're left with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 66

Moving on to step 5:
If we divide 629 by 66, we get 9 and a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 329.0
If we take 594 away from 629, we end up with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 66

Let's proceed to step 6:
66 can be fit into 357 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 3295.0
The remainder is 27 after subtracting 330 from 357.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 66

Advancing to step 7:
271 divided by 66 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 32954.0
If we subtract 264 from 271, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 66

Step 8:
66 can be fit into 73 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 329541.0
Subtract 66 from 73 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
The number 66 fits into 70 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 329541.1
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 329541.1
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
When dividing 400 by 66, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 329541.106
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
40 divided by 66 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 329541.106
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 66, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 329541.10606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 329541.10606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
If we divide 400 by 66, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 329541.1060606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
66 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 329541.1060606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 329541.1060606 and a remainder of 4e-08.
