212340 ÷ 66 
Our goal is to divide 212340 by 66.

Advancing to step 1:
If we divide 2 by 66, we get 0 and 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.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 66

Step 2:
When dividing 21 by 66, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 66

Step 3:
66 goes into 212 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 14 after subtracting 198 from 212.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 66

Step 4:
66 can be fit into 143 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 11 after subtracting 132 from 143.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 66

Let's proceed to step 5:
When dividing 114 by 66, we get 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtracting 66 from 114 leaves us with 48.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 66

Going ahead to step 6:
If we divide 480 by 66, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 3217.0
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 66 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 3217.2
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 66 fits into 480 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 3217.27
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 66 fits into 180 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 3217.272
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
If we divide 480 by 66, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 3217.2727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 66 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 3217.27272
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
66 can be fit into 480 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 3217.272727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
If we divide 180 by 66, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 3217.2727272
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 3217.27272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 3217.27272727, with a leftover of 1.8e-08.
