133012 ÷ 31 
We want to divide 133012 by 31.

On to step 1:
If we divide 1 by 31, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 31

Going ahead to step 2:
31 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 31

Let's proceed to step 3:
31 can be fit into 133 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 124 away from 133, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 31

On to step 4:
90 divided by 31 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 62 from 90 leaves us with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 31

Going ahead to step 5:
281 divided by 31 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 429.0
Deduct 279 from 281 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 31

On to step 6:
The number 31 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 4290.0
Subtracting 0 from 22 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4290.7
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4290.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
If we divide 300 by 31, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 4290.709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4290.7096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 31 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 4290.70967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
230 divided by 31 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 4290.709677
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 4290.709677, with a leftover of 1.3e-06.
