We're dividing 231491 by 66 
We're looking to find how many times 66 goes into 231491.

Moving on to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 66

On to step 2:
66 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 66

Advancing to step 3:
231 divided by 66 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 198 from 231 and we're left with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 66

Advancing to step 4:
66 goes into 334 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 4 after subtracting 330 from 334.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 66

Going ahead to step 5:
If we divide 49 by 66, we get 0 and a remainder of 49.
The next digit of our result is 0. 
Result so far: 350.0
If we take 0 away from 49, we end up with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 66

Advancing to step 6:
When dividing 491 by 66, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 3507.0
If we subtract 462 from 491, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
290 divided by 66 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 3507.4
The remainder is 26 after subtracting 264 from 290.
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 8:
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: 3507.43
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.

Moving on to step 9:
If we divide 620 by 66, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 3507.439
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.

Let's proceed to step 10:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 3507.4393
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.

Advancing to step 11:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 3507.43939
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 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 3507.439393
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.

Step 13:
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: 3507.4393939
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.

Let's proceed to step 14:
260 divided by 66 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 3507.43939393
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.

In conclusion, the division gives 3507.43939393 with a balance of 6.2e-08.
