916423 divided by 66 
Our goal is to divide 916423 by 66.

Step 1:
When dividing 9 by 66, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 66

Let's proceed to step 2:
66 goes into 91 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 91 and we're left with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 66

On to step 3:
When dividing 256 by 66, we get 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 58 after subtracting 198 from 256.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 66

Let's proceed to step 4:
66 goes into 584 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtracting 528 from 584 leaves us with 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 66

Advancing to step 5:
When dividing 562 by 66, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 1388.0
Deduct 528 from 562 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 66

Moving on to step 6:
When dividing 343 by 66, we get 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 13885.0
If we take 330 away from 343, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 66, we get 1 and a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 13885.1
The remainder is 64 after subtracting 66 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 13885.19
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13885.196
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 13885.1969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13885.19696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 13885.196969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13885.1969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 13885.19696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 13885.19696969 with a remainder of 4.6e-08.
