Let's divide 1866 by 22
We're looking to find how many times 22 goes into 1866.

Step 1:
22 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 22

On to step 2:
If we divide 18 by 22, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 22

Moving on to step 3:
22 goes into 186 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 176 from 186 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 22

Step 4:
22 goes into 106 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 88 from 106 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.

On to step 5:
22 goes into 180 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 84.8
Subtract 176 from 180 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 6:
22 goes into 40 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 84.81
Deduct 22 from 40 and we're left 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.

Moving on to step 7:
22 can be fit into 180 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 84.818
The remainder is 4 after subtracting 176 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
22 goes into 40 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 84.8181
Subtracting 22 from 40 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.

Going ahead to step 9:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 84.81818
Deduct 176 from 180 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
If we divide 40 by 22, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 84.818181
Subtracting 22 from 40 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.

Moving on to step 11:
180 divided by 22 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 84.8181818
If we subtract 176 from 180, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 22 fits into 40 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 84.81818181
If we take 22 away from 40, we end up 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.

The final result is 84.81818181 with a remainder of 1.8e-08.
