12043897 divided by 261 
Let's see how many times 261 fits into 12043897.

Step 1:
If we divide 1 by 261, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 261

Step 2:
The number 261 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 261

On to step 3:
120 divided by 261 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Take the next digit (4) from the dividend and append it to 120, then repeat: 1204 / 261

Moving on to step 4:
261 can be fit into 1204 4 times, resulting in a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 160 after subtracting 1044 from 1204.
Append the next digit (3) from the dividend to 160 and continue with: 1603 / 261

Moving on to step 5:
1603 divided by 261 is 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 1566 away from 1603, we end up with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 261

Step 6:
The number 261 fits into 378 1 times, leaving a remainder of 117.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
If we subtract 261 from 378, we get 117.
Append the next digit (9) from the dividend to 117 and continue with: 1179 / 261

On to step 7:
261 goes into 1179 4 times with a remainder of 135.
The number 4 becomes the next digit in our result. 
Result so far: 4614.0
If we take 1044 away from 1179, we end up with 135.
Include the next digit (7) from the dividend after 135, then repeat: 1357 / 261

Moving on to step 8:
1357 divided by 261 is 5 with a remainder of 52.
The next digit of our result is 5. 
Result so far: 46145.0
If we take 1305 away from 1357, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
The number 261 fits into 520 1 times, leaving a remainder of 259.
The next digit of our result is 1. 
Result so far: 46145.1
Subtracting 261 from 520 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 10:
261 can be fit into 2590 9 times, resulting in a remainder of 241.
Write down 9 as next digit of the result. 
Result so far: 46145.19
The remainder is 241 after subtracting 2349 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 11:
The number 261 fits into 2410 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 46145.199
Deduct 2349 from 2410 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 46145.199 and a remainder of 0.0061.
