We look at the division of 115400 by 29 
We're looking to find how many times 29 goes into 115400.

On to step 1:
The number 29 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 29

Step 2:
When dividing 11 by 29, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 29

Advancing to step 3:
115 divided by 29 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 28 after subtracting 87 from 115.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 29

Let's proceed to step 4:
29 goes into 284 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 261 from 284 to get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 29

On to step 5:
29 can be fit into 230 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 397.0
If we take 203 away from 230, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 29

Moving on to step 6:
29 can be fit into 270 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 3979.0
Subtracting 261 from 270 leaves us with 9.
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 7:
29 goes into 90 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3979.3
Subtracting 87 from 90 leaves us 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.

Moving on to step 8:
29 goes into 30 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 3979.31
If we subtract 29 from 30, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 29 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3979.31
Subtract 0 from 10 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.

Let's proceed to step 10:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3979.3103
Subtracting 87 from 100 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.

On to step 11:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3979.31034
Deduct 116 from 130 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
140 divided by 29 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3979.310344
Subtract 116 from 140 to 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.

In conclusion, the division gives 3979.310344 with a balance of 2.4e-06.
