56752308 ÷ 129 
We're looking to find how many times 129 goes into 56752308.

Advancing to step 1:
When dividing 5 by 129, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 129

Going ahead to step 2:
56 divided by 129 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 129

Step 3:
When dividing 567 by 129, we get 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 516 from 567 leaves us with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 129

Going ahead to step 4:
515 divided by 129 is 3 with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 387 from 515 and we're left with 128.
Take the next digit (2) from the dividend and append it to 128, then repeat: 1282 / 129

Going ahead to step 5:
The number 129 fits into 1282 9 times, leaving a remainder of 121.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
If we take 1161 away from 1282, we end up with 121.
Fetch the next digit (3) from the dividend, attach it to 121 and continue: 1213 / 129

Moving on to step 6:
129 can be fit into 1213 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 4399.0
Deduct 1161 from 1213 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 129

On to step 7:
129 can be fit into 520 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 43994.0
Subtracting 516 from 520 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 129

Advancing to step 8:
The number 129 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 439940.0
The remainder is 48 after subtracting 0 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 129, we get 3 and a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 439940.3
Subtract 387 from 480 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 10:
129 goes into 930 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 439940.37
If we subtract 903 from 930, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
129 goes into 270 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 439940.372
If we take 258 away from 270, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
129 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 439940.372
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
The number 129 fits into 1200 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 439940.37209
Deduct 1161 from 1200 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 14:
129 can be fit into 390 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 439940.372093
Deduct 387 from 390 and we're left 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.

Advancing to step 15:
When dividing 30 by 129, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 439940.372093
If we take 0 away from 30, 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.

On to step 16:
If we divide 300 by 129, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 439940.37209302
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 439940.37209302 with a balance of 4.2e-08.
