We look at the division of 258149 by 5 
We want to figure out the number of times 258149 can be divided by 5.

Advancing to step 1:
The number 5 fits into 2 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 5

Step 2:
If we divide 25 by 5, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 25 from 25 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 5

Step 3:
5 goes into 8 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 5 from 8 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 5

On to step 4:
5 can be fit into 31 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 516.0
The remainder is 1 after subtracting 30 from 31.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 5

Moving on to step 5:
5 goes into 14 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 5162.0
If we take 10 away from 14, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

Going ahead to step 6:
If we divide 49 by 5, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 51629.0
Deduct 45 from 49 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 51629.8
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51629.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51629.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 51629.8, and the remainder is 0.0.
