We're dividing 31147758 by 129 
We're looking to find how many times 129 goes into 31147758.

On to step 1:
129 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 129

Going ahead to step 2:
129 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 129

Going ahead to step 3:
129 goes into 311 2 times with a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 258 away from 311, we end up with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 129

Advancing to step 4:
If we divide 534 by 129, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 516 away from 534, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 129

Step 5:
187 divided by 129 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
Deduct 129 from 187 and we're left with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 129

Moving on to step 6:
587 divided by 129 is 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 2414.0
If we subtract 516 from 587, we get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 129

Going ahead to step 7:
If we divide 715 by 129, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 24145.0
If we take 645 away from 715, we end up with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 129

Advancing to step 8:
708 divided by 129 is 5 with a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 241455.0
Deduct 645 from 708 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
When dividing 630 by 129, we get 4 with a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 241455.4
If we subtract 516 from 630, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
1140 divided by 129 is 8 with a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 241455.48
If we take 1032 away from 1140, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
1080 divided by 129 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 241455.488
The remainder is 48 after subtracting 1032 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 241455.488 with a balance of 0.0048.
