12343119 ÷ 259 
We're looking to find how many times 259 goes into 12343119.

Moving on to step 1:
The number 259 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 259

Moving on to step 2:
259 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 259

Advancing to step 3:
259 can be fit into 123 0 times, resulting in a remainder of 123.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Append the next digit (4) from the dividend to 123 and continue with: 1234 / 259

Advancing to step 4:
If we divide 1234 by 259, we get 4 and a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1036 from 1234 and we're left with 198.
Take the next digit (3) from the dividend and append it to 198, then repeat: 1983 / 259

Step 5:
The number 259 fits into 1983 7 times, leaving a remainder of 170.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 1813 from 1983 leaves us with 170.
Include the next digit (1) from the dividend after 170, then repeat: 1701 / 259

Let's proceed to step 6:
The number 259 fits into 1701 6 times, leaving a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 476.0
If we take 1554 away from 1701, we end up with 147.
Bring next digit (1) of the dividend behind the 147 and repeat the process: 1471 / 259

Advancing to step 7:
When dividing 1471 by 259, we get 5 with a remainder of 176.
Put 5 as the next digit of the answer. 
Result so far: 4765.0
If we take 1295 away from 1471, we end up with 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 259

Let's proceed to step 8:
1769 divided by 259 is 6 with a remainder of 215.
Record the quotient 6 as the next digit in the result. 
Result so far: 47656.0
If we take 1554 away from 1769, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
The number 259 fits into 2150 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 47656.8
Subtract 2072 from 2150 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
When dividing 780 by 259, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 47656.83
Deduct 777 from 780 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
The number 259 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 47656.83
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 259, we get 1 and a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 47656.8301
If we subtract 259 from 300, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 13:
The number 259 fits into 410 1 times, leaving a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 47656.83011
Deduct 259 from 410 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final result is 47656.83011 with a remainder of 0.000151.
