Let's divide 9159230 by 664
We're looking to find how many times 664 goes into 9159230.

Step 1:
664 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 664

Step 2:
664 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 664

Moving on to step 3:
The number 664 fits into 915 1 times, leaving a remainder of 251.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 664 from 915 and we're left with 251.
Append the next digit (9) from the dividend to 251 and continue with: 2519 / 664

On to step 4:
The number 664 fits into 2519 3 times, leaving a remainder of 527.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 527 after subtracting 1992 from 2519.
Include the next digit (2) from the dividend after 527, then repeat: 5272 / 664

Let's proceed to step 5:
When dividing 5272 by 664, we get 7 with a remainder of 624.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 4648 from 5272 and we're left with 624.
Take the next digit (3) from the dividend and append it to 624, then repeat: 6243 / 664

Step 6:
The number 664 fits into 6243 9 times, leaving a remainder of 267.
The number 9 becomes the next digit in our result. 
Result so far: 1379.0
Deduct 5976 from 6243 and we're left with 267.
Bring next digit (0) of the dividend behind the 267 and repeat the process: 2670 / 664

Advancing to step 7:
664 can be fit into 2670 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 13794.0
The remainder is 14 after subtracting 2656 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
664 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 13794.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 9:
If we divide 1400 by 664, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 13794.02
Subtract 1328 from 1400 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
664 can be fit into 720 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 13794.021
If we subtract 664 from 720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
The number 664 fits into 560 0 times, leaving a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 13794.021
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
The number 664 fits into 5600 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 13794.02108
If we subtract 5312 from 5600, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
When dividing 2880 by 664, we get 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 13794.021084
Deduct 2656 from 2880 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
664 can be fit into 2240 3 times, resulting in a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 13794.0210843
Deduct 1992 from 2240 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 15:
664 can be fit into 2480 3 times, resulting in a remainder of 488.
Put 3 as the next digit of the answer. 
Result so far: 13794.02108433
If we take 1992 away from 2480, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final outcome is 13794.02108433, with a leftover of 4.88e-07.
