We look at the division of 909407 by 66 
Let's see how many times 66 fits into 909407.

Step 1:
66 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 66

Advancing to step 2:
The number 66 fits into 90 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 66 from 90 to get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 66

Going ahead to step 3:
66 can be fit into 249 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 198 from 249 leaves us with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 66

Advancing to step 4:
66 can be fit into 514 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we subtract 462 from 514, we get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 66

Let's proceed to step 5:
If we divide 520 by 66, we get 7 and a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1377.0
If we take 462 away from 520, we end up with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 66

Moving on to step 6:
When dividing 587 by 66, we get 8 with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 13778.0
If we take 528 away from 587, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
The number 66 fits into 590 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 13778.8
Subtracting 528 from 590 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.

Moving on to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 13778.89
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.

On to step 9:
When dividing 260 by 66, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 13778.893
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.

Moving on to step 10:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 13778.8939
Subtract 594 from 620 to get 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 11:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 13778.89393
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.

Going ahead to step 12:
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: 13778.893939
Subtract 594 from 620 to get 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 13:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 13778.8939393
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.

Let's proceed to step 14:
620 divided by 66 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 13778.89393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 13778.89393939 and a remainder of 2.6e-08.
