We're dividing 131201 by 45 
We're looking to find how many times 45 goes into 131201.

On to step 1:
45 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 45

Moving on to step 2:
If we divide 13 by 45, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 45

On to step 3:
131 divided by 45 is 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 90 away from 131, we end up with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 45

Let's proceed to step 4:
412 divided by 45 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 405 from 412 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 45

Advancing to step 5:
If we divide 70 by 45, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Subtract 45 from 70 to get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 45

On to step 6:
If we divide 251 by 45, we get 5 and a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 2915.0
If we take 225 away from 251, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
45 goes into 260 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2915.5
Deduct 225 from 260 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 2915.57
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 2915.577
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 2915.577 with a balance of 0.0035.
