Let's divide 307871 by 66
We want to divide 307871 by 66.

Going ahead to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 66

Step 2:
66 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 66

Advancing to step 3:
If we divide 307 by 66, we get 4 and a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 264 away from 307, we end up with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 66

Advancing to step 4:
When dividing 438 by 66, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 396 from 438 leaves us with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 66

On to step 5:
If we divide 427 by 66, we get 6 and a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Subtract 396 from 427 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 66

Going ahead to step 6:
311 divided by 66 is 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4664.0
Subtracting 264 from 311 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
When dividing 470 by 66, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 4664.7
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 66, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 4664.71
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
66 goes into 140 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4664.712
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
66 goes into 80 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 4664.7121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4664.71212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 4664.712121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 66, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4664.7121212
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 66 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 4664.71212121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 4664.71212121, with a leftover of 1.4e-08.
