20229159 ÷ 259 
We're looking to find how many times 259 goes into 20229159.

Step 1:
When dividing 2 by 259, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 259

Let's proceed to step 2:
259 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 259

Advancing to step 3:
202 divided by 259 is 0 with a remainder of 202.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 202 leaves us with 202.
Bring next digit (2) of the dividend behind the 202 and repeat the process: 2022 / 259

Let's proceed to step 4:
When dividing 2022 by 259, we get 7 with a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 1813 from 2022, we get 209.
Include the next digit (9) from the dividend after 209, then repeat: 2099 / 259

Step 5:
If we divide 2099 by 259, we get 8 and a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 2072 from 2099 to get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 259

Going ahead to step 6:
271 divided by 259 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
If we subtract 259 from 271, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 259

Step 7:
When dividing 125 by 259, we get 0 with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 7810.0
Deduct 0 from 125 and we're left with 125.
Append the next digit (9) from the dividend to 125 and continue with: 1259 / 259

Moving on to step 8:
1259 divided by 259 is 4 with a remainder of 223.
Write down 4 as next digit of the result. 
Result so far: 78104.0
If we subtract 1036 from 1259, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 9:
2230 divided by 259 is 8 with a remainder of 158.
The number 8 becomes the next digit in our result. 
Result so far: 78104.8
Subtract 2072 from 2230 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
When dividing 1580 by 259, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 78104.86
If we take 1554 away from 1580, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
259 goes into 260 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 78104.861
Subtracting 259 from 260 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
259 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 78104.861
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
The number 259 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 78104.861
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 78104.861 with a remaining 0.0001.
