We're dividing 5189723 by 425 
Let's see how many times 425 fits into 5189723.

Going ahead to step 1:
The number 425 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 425

On to step 2:
The number 425 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 425

Going ahead to step 3:
425 goes into 518 1 times with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 425 from 518 leaves us with 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 425

Let's proceed to step 4:
When dividing 939 by 425, we get 2 with a remainder of 89.
The next digit of our result is 2. 
Result so far: 12.0
If we take 850 away from 939, we end up with 89.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 425

Going ahead to step 5:
If we divide 897 by 425, we get 2 and a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Subtracting 850 from 897 leaves us with 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 425

Going ahead to step 6:
472 divided by 425 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
Subtract 425 from 472 to get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 425

Step 7:
When dividing 473 by 425, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 12211.0
If we subtract 425 from 473, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
When dividing 480 by 425, we get 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 12211.1
If we subtract 425 from 480, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
550 divided by 425 is 1 with a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 12211.11
The remainder is 125 after subtracting 425 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 12211.11 and a remainder of 0.125.
