Let's divide 61275648 by 129
Our goal is to divide 61275648 by 129.

Step 1:
The number 129 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 129

Step 2:
129 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 129

On to step 3:
129 can be fit into 612 4 times, resulting in a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 516 away from 612, we end up with 96.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 129

Advancing to step 4:
If we divide 967 by 129, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 47.0
The remainder is 64 after subtracting 903 from 967.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 129

Going ahead to step 5:
129 goes into 645 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 475.0
Subtracting 645 from 645 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 129

Step 6:
129 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 4750.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 129

Moving on to step 7:
If we divide 64 by 129, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 47500.0
Subtract 0 from 64 to get 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 129

Going ahead to step 8:
129 goes into 648 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 475005.0
If we subtract 645 from 648, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 129 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 475005.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 129 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 475005.02
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
The number 129 fits into 420 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 475005.023
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
When dividing 330 by 129, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 475005.0232
The remainder is 72 after subtracting 258 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
The number 129 fits into 720 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 475005.02325
Deduct 645 from 720 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 129 is 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 475005.023255
Subtract 645 from 750 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 475005.023255 with a remainder of 1.05e-05.
