We look at the division of 14155920 by 66 
Our goal is to divide 14155920 by 66.

Going ahead to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 66

On to step 2:
66 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 66

On to step 3:
When dividing 141 by 66, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 9 after subtracting 132 from 141.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 66

Moving on to step 4:
66 goes into 95 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 66 from 95, we get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 66

Going ahead to step 5:
When dividing 295 by 66, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 214.0
Deduct 264 from 295 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 66

Advancing to step 6:
66 can be fit into 319 4 times, resulting in a remainder of 55.
The next digit of our result is 4. 
Result so far: 2144.0
If we take 264 away from 319, we end up with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 66

Let's proceed to step 7:
If we divide 552 by 66, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 21448.0
Subtract 528 from 552 to get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 66

Step 8:
66 goes into 240 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 214483.0
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 66, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 214483.6
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 214483.63
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 214483.636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
66 goes into 240 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 214483.6363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 214483.63636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 214483.636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 15:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 214483.6363636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
66 goes into 240 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 214483.63636363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 214483.63636363 with a remainder of 4.2e-08.
