We're dividing 212381 by 66 
We want to figure out the number of times 212381 can be divided by 66.

Moving on to step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 66

Let's proceed to step 2:
66 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
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

Going ahead to step 3:
212 divided by 66 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 198 from 212 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 66

Advancing to step 4:
66 goes into 143 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 132 from 143 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 66

Let's proceed to step 5:
When dividing 118 by 66, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 321.0
If we take 66 away from 118, we end up with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 66

Going ahead to step 6:
If we divide 521 by 66, we get 7 and a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 3217.0
If we subtract 462 from 521, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
590 divided by 66 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3217.8
If we subtract 528 from 590, 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.

Going ahead to step 8:
620 divided by 66 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 3217.89
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.

Moving on to step 9:
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: 3217.893
Subtracting 198 from 260 leaves us 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 10:
620 divided by 66 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 3217.8939
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 11:
When dividing 260 by 66, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 3217.89393
If we take 198 away from 260, we end up 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 12:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 3217.893939
Subtract 594 from 620 to 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.

Let's proceed to step 13:
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: 3217.8939393
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.

Advancing to step 14:
620 divided by 66 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 3217.89393939
Subtract 594 from 620 to 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.

Our division results in 3217.89393939 with a remaining 2.6e-08.
