We're dividing 259667 by 66 
We want to figure out the number of times 259667 can be divided by 66.

Advancing to step 1:
2 divided by 66 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 66

On to step 2:
The number 66 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 66

On to step 3:
If we divide 259 by 66, we get 3 and a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 198 from 259, we get 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 66

Advancing to step 4:
When dividing 616 by 66, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 594 from 616, we get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 66

Moving on to step 5:
66 goes into 226 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 393.0
Subtracting 198 from 226 leaves us with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 66

Going ahead to step 6:
The number 66 fits into 287 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 3934.0
If we take 264 away from 287, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
When dividing 230 by 66, we get 3 with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 3934.3
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
When dividing 320 by 66, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3934.34
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3934.348
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
320 divided by 66 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 3934.3484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 66 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 3934.34848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 66 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 3934.348484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
560 divided by 66 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3934.3484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 66, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 3934.34848484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 3934.34848484, with a leftover of 5.6e-08.
