We look at the division of 623592 by 66 
Let's see how many times 66 fits into 623592.

Moving on to step 1:
66 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 66

Advancing to step 2:
If we divide 62 by 66, we get 0 and a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 66

Step 3:
66 goes into 623 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 594 from 623 and we're left with 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 66

On to step 4:
66 goes into 295 4 times with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtract 264 from 295 to get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 66

Step 5:
If we divide 319 by 66, we get 4 and a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 944.0
If we subtract 264 from 319, we get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 66

Advancing to step 6:
If we divide 552 by 66, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 9448.0
Subtracting 528 from 552 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
240 divided by 66 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9448.3
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9448.36
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 66, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9448.363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 9448.3636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9448.36363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 9448.363636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
When dividing 240 by 66, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9448.3636363
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 9448.36363636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 9448.36363636, with a leftover of 2.4e-08.
