Let's divide 253984 by 66
We're looking to find how many times 66 goes into 253984.

On to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 66

Step 2:
66 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 66

Moving on to step 3:
The number 66 fits into 253 3 times, leaving a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 198 from 253 to get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 66

Advancing to step 4:
559 divided by 66 is 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 528 from 559 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 66

Let's proceed to step 5:
The number 66 fits into 318 4 times, leaving a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 384.0
Subtracting 264 from 318 leaves us with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 66

On to step 6:
66 goes into 544 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3848.0
If we subtract 528 from 544, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
If we divide 160 by 66, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 3848.2
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
66 can be fit into 280 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3848.24
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 66, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 3848.242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 66 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 3848.2424
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 66 fits into 160 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3848.24242
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
280 divided by 66 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3848.242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 66, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3848.2424242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
The number 66 fits into 280 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 3848.24242424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3848.24242424 with a remaining 1.6e-08.
