6143395 ÷ 923 
Let's see how many times 923 fits into 6143395.

Going ahead to step 1:
When dividing 6 by 923, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 923

Going ahead to step 2:
When dividing 61 by 923, we get 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 923

Going ahead to step 3:
If we divide 614 by 923, we get 0 and a remainder of 614.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 614, we get 614.
Grab the next digit (3) from the dividend, add it to 614, then carry on: 6143 / 923

Going ahead to step 4:
If we divide 6143 by 923, we get 6 and a remainder of 605.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5538 from 6143 and we're left with 605.
Append the next digit (3) from the dividend to 605 and continue with: 6053 / 923

Going ahead to step 5:
6053 divided by 923 is 6 with a remainder of 515.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 5538 from 6053 to get 515.
Grab the next digit (9) from the dividend, add it to 515, then carry on: 5159 / 923

Step 6:
923 can be fit into 5159 5 times, resulting in a remainder of 544.
Put 5 as the next digit of the answer. 
Result so far: 665.0
If we subtract 4615 from 5159, we get 544.
Include the next digit (5) from the dividend after 544, then repeat: 5445 / 923

On to step 7:
If we divide 5445 by 923, we get 5 and a remainder of 830.
Record the quotient 5 as the next digit in the result. 
Result so far: 6655.0
Subtracting 4615 from 5445 leaves us with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Going ahead to step 8:
923 goes into 8300 8 times with a remainder of 916.
Record the quotient 8 as the next digit in the result. 
Result so far: 6655.8
If we subtract 7384 from 8300, we get 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

On to step 9:
If we divide 9160 by 923, we get 9 and a remainder of 853.
The next digit of our result is 9. 
Result so far: 6655.89
Subtracting 8307 from 9160 leaves us with 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Going ahead to step 10:
8530 divided by 923 is 9 with a remainder of 223.
The number 9 becomes the next digit in our result. 
Result so far: 6655.899
If we take 8307 away from 8530, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

After the division, we end up with 6655.899 and a remainder of 0.0223.
