23786817 ÷ 259 
Let's see how many times 259 fits into 23786817.

Let's proceed to step 1:
2 divided by 259 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 259

Going ahead to step 2:
The number 259 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 259

Going ahead to step 3:
The number 259 fits into 237 0 times, leaving a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 237 after subtracting 0 from 237.
Include the next digit (8) from the dividend after 237, then repeat: 2378 / 259

Going ahead to step 4:
2378 divided by 259 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 2331 from 2378 leaves us with 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 259

Moving on to step 5:
259 can be fit into 476 1 times, resulting in a remainder of 217.
The next digit of our result is 1. 
Result so far: 91.0
If we take 259 away from 476, we end up with 217.
Append the next digit (8) from the dividend to 217 and continue with: 2178 / 259

Advancing to step 6:
259 goes into 2178 8 times with a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 918.0
If we take 2072 away from 2178, we end up with 106.
Take the next digit (1) from the dividend and append it to 106, then repeat: 1061 / 259

Going ahead to step 7:
If we divide 1061 by 259, we get 4 and a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 9184.0
Subtracting 1036 from 1061 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 259

Advancing to step 8:
259 goes into 257 0 times with a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 91840.0
If we take 0 away from 257, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 9:
The number 259 fits into 2570 9 times, leaving a remainder of 239.
Use 9 as the next digit of our solution. 
Result so far: 91840.9
Subtract 2331 from 2570 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 10:
259 goes into 2390 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 91840.99
Deduct 2331 from 2390 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 91840.99 and a remainder of 0.059.
