259021 ÷ 79 
We want to figure out the number of times 259021 can be divided by 79.

Let's proceed to step 1:
2 divided by 79 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 79

On to step 2:
79 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 79

Let's proceed to step 3:
The number 79 fits into 259 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 3.0
If we take 237 away from 259, we end up with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 79

Step 4:
If we divide 220 by 79, we get 2 and a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 158 away from 220, we end up with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 79

On to step 5:
79 can be fit into 622 7 times, resulting in a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
If we take 553 away from 622, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 79

Step 6:
79 can be fit into 691 8 times, resulting in a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 3278.0
Subtracting 632 from 691 leaves us 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.

Advancing to step 7:
79 can be fit into 590 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 3278.7
Subtracting 553 from 590 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
79 goes into 370 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 3278.74
Subtracting 316 from 370 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 79, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 3278.746
Subtracting 474 from 540 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
79 can be fit into 660 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3278.7468
If we subtract 632 from 660, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 79, we get 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 3278.74683
Subtract 237 from 280 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3278.746835
If we subtract 395 from 430, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
350 divided by 79 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 3278.7468354
Subtracting 316 from 350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
79 can be fit into 340 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 3278.74683544
Subtracting 316 from 340 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3278.74683544 and a remainder of 2.4e-08.
