258286 divided by 79 
Let's see how many times 79 fits into 258286.

On to step 1:
79 goes into 2 0 times 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 79

On to step 2:
The number 79 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 79

On to step 3:
79 can be fit into 258 3 times, resulting in a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 237 from 258 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 79

Advancing to step 4:
79 can be fit into 212 2 times, resulting in a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 158 from 212 to get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 79

Going ahead to step 5:
If we divide 548 by 79, we get 6 and a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 326.0
The remainder is 74 after subtracting 474 from 548.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 79

Moving on to step 6:
When dividing 746 by 79, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 3269.0
If we subtract 711 from 746, 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.

Advancing to step 7:
79 can be fit into 350 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 3269.4
If we take 316 away from 350, we end up 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 8:
If we divide 340 by 79, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3269.44
Deduct 316 from 340 and we're left 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.

The quotient of the division is 3269.44, and the remainder is 0.024.
