Let's divide 69448960 by 129
Our goal is to divide 69448960 by 129.

Going ahead to step 1:
6 divided by 129 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 129

Step 2:
The number 129 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 129

Moving on to step 3:
694 divided by 129 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 645 from 694 to get 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 129

Step 4:
The number 129 fits into 494 3 times, leaving a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 387 from 494 leaves us with 107.
Bring next digit (8) of the dividend behind the 107 and repeat the process: 1078 / 129

Advancing to step 5:
If we divide 1078 by 129, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 538.0
Subtracting 1032 from 1078 leaves us with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 129

Step 6:
129 goes into 469 3 times with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 5383.0
The remainder is 82 after subtracting 387 from 469.
Fetch the next digit (6) from the dividend, attach it to 82 and continue: 826 / 129

Let's proceed to step 7:
When dividing 826 by 129, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 53836.0
If we take 774 away from 826, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 129

Let's proceed to step 8:
If we divide 520 by 129, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 538364.0
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
129 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 538364.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 129 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 538364.03
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
129 can be fit into 130 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 538364.031
If we subtract 129 from 130, 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.

On to step 12:
The number 129 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 538364.031
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 129, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 538364.031
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 538364.031 with a remaining 0.0001.
