Let's divide 117509 by 66
Our goal is to divide 117509 by 66.

Going ahead to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 66

Step 2:
When dividing 11 by 66, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 66

Step 3:
66 can be fit into 117 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 66 from 117 and we're left with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 66

Step 4:
If we divide 515 by 66, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 462 from 515, we get 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 66

Let's proceed to step 5:
66 can be fit into 530 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 178.0
Subtract 528 from 530 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 66

Let's proceed to step 6:
The number 66 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 1780.0
If we take 0 away from 29, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 66 fits into 290 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1780.4
If we subtract 264 from 290, 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.

Step 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 1780.43
Subtract 198 from 260 to 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 9:
620 divided by 66 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1780.439
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.

Moving on to step 10:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 1780.4393
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.

Let's proceed to step 11:
66 can be fit into 620 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 1780.43939
Deduct 594 from 620 and we're left 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.

Going ahead to step 12:
66 goes into 260 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 1780.439393
Subtract 198 from 260 to 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:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 1780.4393939
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.

On to step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 1780.43939393
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.

Our division results in 1780.43939393 with a remaining 6.2e-08.
