Let's divide 125319 by 4
Let's see how many times 4 fits into 125319.

Advancing to step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Advancing to step 2:
12 divided by 4 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Step 3:
4 goes into 5 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Advancing to step 4:
If we divide 13 by 4, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 313.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 4

Step 5:
When dividing 11 by 4, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 3132.0
Subtract 8 from 11 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

On to step 6:
The number 4 fits into 39 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 31329.0
If we subtract 36 from 39, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 4 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 31329.7
Deduct 28 from 30 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.

Step 8:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 31329.75
If we subtract 20 from 20, 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 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31329.75
If we take 0 away from 0, we end up 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.

Moving on to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31329.75
If we subtract 0 from 0, 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.

After the division, we end up with 31329.75 and a remainder of 0.0.
