We're dividing 126530 by 31 
We want to divide 126530 by 31.

On to step 1:
31 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 31

Step 2:
If we divide 12 by 31, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 31

Let's proceed to step 3:
126 divided by 31 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 124 away from 126, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 31

Let's proceed to step 4:
31 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 31

Step 5:
If we divide 253 by 31, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
The remainder is 5 after subtracting 248 from 253.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 31

Advancing to step 6:
50 divided by 31 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 4081.0
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
31 goes into 190 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4081.6
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
31 goes into 40 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 4081.61
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4081.612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
When dividing 280 by 31, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4081.6129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
When dividing 10 by 31, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4081.6129
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 31, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4081.612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
31 can be fit into 70 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4081.6129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 4081.61290322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 4081.61290322 with a remainder of 1.8e-08.
