We divide 131115 by 45
We want to divide 131115 by 45.

Going ahead to step 1:
45 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 45

Advancing to step 2:
The number 45 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 45

Let's proceed to step 3:
45 can be fit into 131 2 times, resulting in a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 41 after subtracting 90 from 131.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 45

Step 4:
If we divide 411 by 45, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 6 after subtracting 405 from 411.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

On to step 5:
45 goes into 61 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 291.0
If we take 45 away from 61, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 45

Moving on to step 6:
165 divided by 45 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2913.0
If we take 135 away from 165, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 2913.6
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 2913.66
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 2913.66 with a remainder of 0.03.
