238951 ÷ 66 
We want to figure out the number of times 238951 can be divided by 66.

On to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 66

Advancing to step 2:
The number 66 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 66

Advancing to step 3:
If we divide 238 by 66, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 198 from 238, we get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 66

Advancing to step 4:
66 can be fit into 409 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 396 from 409, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 66

Step 5:
The number 66 fits into 135 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 362.0
The remainder is 3 after subtracting 132 from 135.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 66

Going ahead to step 6:
When dividing 31 by 66, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 3620.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 66 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 3620.4
Deduct 264 from 310 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
If we divide 460 by 66, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3620.46
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
When dividing 640 by 66, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3620.469
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 3620.4696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
If we divide 640 by 66, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 3620.46969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 66, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3620.469696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3620.4696969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3620.46969696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 3620.46969696, with a leftover of 6.4e-08.
