We're dividing 20458 by 79 
We're looking to find how many times 79 goes into 20458.

Going ahead to step 1:
When dividing 2 by 79, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 79

Moving on to step 2:
20 divided by 79 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 79

Let's proceed to step 3:
The number 79 fits into 204 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 158 from 204 leaves us with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 79

Let's proceed to step 4:
If we divide 465 by 79, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 395 from 465 to get 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 79

On to step 5:
79 goes into 708 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we subtract 632 from 708, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 6:
When dividing 760 by 79, we get 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 258.9
Deduct 711 from 760 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
When dividing 490 by 79, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 258.96
If we take 474 away from 490, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
79 can be fit into 160 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 258.962
Deduct 158 from 160 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 79, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 258.962
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 79, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 258.96202
The remainder is 42 after subtracting 158 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
The number 79 fits into 420 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 258.962025
The remainder is 25 after subtracting 395 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
The number 79 fits into 250 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 258.9620253
Subtract 237 from 250 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
79 goes into 130 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 258.96202531
If we subtract 79 from 130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 258.96202531, and the remainder is 5.1e-08.
