We look at the division of 43258461 by 904 
Our goal is to divide 43258461 by 904.

Step 1:
904 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 904

Going ahead to step 2:
If we divide 43 by 904, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 904

Step 3:
If we divide 432 by 904, we get 0 and a remainder of 432.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 432 leaves us with 432.
Include the next digit (5) from the dividend after 432, then repeat: 4325 / 904

Advancing to step 4:
904 can be fit into 4325 4 times, resulting in a remainder of 709.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3616 away from 4325, we end up with 709.
Take the next digit (8) from the dividend and append it to 709, then repeat: 7098 / 904

Moving on to step 5:
904 goes into 7098 7 times with a remainder of 770.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 6328 from 7098 to get 770.
Include the next digit (4) from the dividend after 770, then repeat: 7704 / 904

Let's proceed to step 6:
When dividing 7704 by 904, we get 8 with a remainder of 472.
Write down 8 as next digit of the result. 
Result so far: 478.0
Deduct 7232 from 7704 and we're left with 472.
Fetch the next digit (6) from the dividend, attach it to 472 and continue: 4726 / 904

Advancing to step 7:
904 goes into 4726 5 times with a remainder of 206.
The next digit of our result is 5. 
Result so far: 4785.0
Subtract 4520 from 4726 to get 206.
Include the next digit (1) from the dividend after 206, then repeat: 2061 / 904

Step 8:
904 goes into 2061 2 times with a remainder of 253.
Use 2 as the next digit of our solution. 
Result so far: 47852.0
The remainder is 253 after subtracting 1808 from 2061.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
2530 divided by 904 is 2 with a remainder of 722.
Put 2 as the next digit of the answer. 
Result so far: 47852.2
Deduct 1808 from 2530 and we're left with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

On to step 10:
7220 divided by 904 is 7 with a remainder of 892.
Put 7 as the next digit of the answer. 
Result so far: 47852.27
The remainder is 892 after subtracting 6328 from 7220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Let's proceed to step 11:
The number 904 fits into 8920 9 times, leaving a remainder of 784.
Use 9 as the next digit of our solution. 
Result so far: 47852.279
If we take 8136 away from 8920, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 12:
The number 904 fits into 7840 8 times, leaving a remainder of 608.
The next digit of our result is 8. 
Result so far: 47852.2798
Subtracting 7232 from 7840 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
If we divide 6080 by 904, we get 6 and a remainder of 656.
Record the quotient 6 as the next digit in the result. 
Result so far: 47852.27986
Subtract 5424 from 6080 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 14:
6560 divided by 904 is 7 with a remainder of 232.
Use 7 as the next digit of our solution. 
Result so far: 47852.279867
The remainder is 232 after subtracting 6328 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 15:
904 goes into 2320 2 times with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 47852.2798672
Subtracting 1808 from 2320 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 16:
904 can be fit into 5120 5 times, resulting in a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 47852.27986725
If we subtract 4520 from 5120, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 47852.27986725 with a remainder of 6e-07.
