27275243 divided by 129 
Let's see how many times 129 fits into 27275243.

Going ahead to step 1:
If we divide 2 by 129, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 129

Advancing to step 2:
When dividing 27 by 129, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 129

Going ahead to step 3:
129 goes into 272 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 14 after subtracting 258 from 272.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 129

Advancing to step 4:
The number 129 fits into 147 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 129 from 147 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 129

Moving on to step 5:
When dividing 185 by 129, we get 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
Subtract 129 from 185 to get 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 129

Going ahead to step 6:
129 goes into 562 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 2114.0
The remainder is 46 after subtracting 516 from 562.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 129

Going ahead to step 7:
If we divide 464 by 129, we get 3 and a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 21143.0
The remainder is 77 after subtracting 387 from 464.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 129

Moving on to step 8:
When dividing 773 by 129, we get 5 with a remainder of 128.
The next digit of our result is 5. 
Result so far: 211435.0
If we take 645 away from 773, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
1280 divided by 129 is 9 with a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 211435.9
If we take 1161 away from 1280, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 10:
129 can be fit into 1190 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 211435.99
Subtracting 1161 from 1190 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 211435.99 and a remainder of 0.029.
