Let's divide 129541 by 30
Let's see how many times 30 fits into 129541.

Step 1:
1 divided by 30 is 0 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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Step 2:
The number 30 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 30

On to step 3:
30 can be fit into 129 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 9 after subtracting 120 from 129.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 30

Advancing to step 4:
95 divided by 30 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 90 from 95 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 30

Advancing to step 5:
54 divided by 30 is 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
If we take 30 away from 54, we end up with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 30

Moving on to step 6:
When dividing 241 by 30, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 4318.0
Deduct 240 from 241 and we're left 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.

Going ahead to step 7:
30 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4318.0
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.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 4318.03
Subtract 90 from 100 to get 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 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 4318.033
Deduct 90 from 100 and we're left 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.

The final outcome is 4318.033, with a leftover of 0.001.
