125811 ÷ 5 
Let's see how many times 5 fits into 125811.

Moving on to step 1:
1 divided by 5 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 5

Step 2:
If we divide 12 by 5, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 10 from 12, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 5

Advancing to step 3:
The number 5 fits into 25 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 25 away from 25, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 5

Moving on to step 4:
When dividing 8 by 5, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
Subtracting 5 from 8 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 5

Step 5:
31 divided by 5 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 2516.0
If we take 30 away from 31, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 5

Let's proceed to step 6:
When dividing 11 by 5, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 25162.0
Subtract 10 from 11 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 5 fits into 10 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 25162.2
If we subtract 10 from 10, we 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.

Step 8:
5 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25162.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25162.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 25162.2 with a remaining 0.0.
