We look at the division of 43394599 by 904 
Our goal is to divide 43394599 by 904.

Moving on to step 1:
904 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 904

Going ahead to step 2:
43 divided by 904 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 904

Step 3:
When dividing 433 by 904, we get 0 with a remainder of 433.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 433 and we're left with 433.
Take the next digit (9) from the dividend and append it to 433, then repeat: 4339 / 904

Advancing to step 4:
If we divide 4339 by 904, we get 4 and a remainder of 723.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3616 from 4339 leaves us with 723.
Bring next digit (4) of the dividend behind the 723 and repeat the process: 7234 / 904

Let's proceed to step 5:
When dividing 7234 by 904, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 7232 from 7234 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 904

Moving on to step 6:
When dividing 25 by 904, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 480.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 904

Step 7:
904 can be fit into 259 0 times, resulting in a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 4800.0
Subtract 0 from 259 to get 259.
Grab the next digit (9) from the dividend, add it to 259, then carry on: 2599 / 904

Let's proceed to step 8:
2599 divided by 904 is 2 with a remainder of 791.
Put 2 as the next digit of the answer. 
Result so far: 48002.0
Subtracting 1808 from 2599 leaves us with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Step 9:
The number 904 fits into 7910 8 times, leaving a remainder of 678.
Write down 8 as next digit of the result. 
Result so far: 48002.8
If we subtract 7232 from 7910, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Let's proceed to step 10:
If we divide 6780 by 904, we get 7 and a remainder of 452.
The next digit of our result is 7. 
Result so far: 48002.87
Subtract 6328 from 6780 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 11:
The number 904 fits into 4520 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 48002.875
Deduct 4520 from 4520 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 904, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48002.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
When dividing 0 by 904, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48002.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 48002.875 with a remainder of 0.0.
