We're dividing 70004559 by 129 
We want to divide 70004559 by 129.

Step 1:
129 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 129

Let's proceed to step 2:
70 divided by 129 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 129

Going ahead to step 3:
The number 129 fits into 700 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 55 after subtracting 645 from 700.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 129

Advancing to step 4:
129 goes into 550 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 34 after subtracting 516 from 550.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 129

Going ahead to step 5:
129 can be fit into 344 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
Subtracting 258 from 344 leaves us with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 129

On to step 6:
If we divide 865 by 129, we get 6 and a remainder of 91.
The next digit of our result is 6. 
Result so far: 5426.0
If we take 774 away from 865, we end up with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 129

Advancing to step 7:
129 can be fit into 915 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 54267.0
Subtract 903 from 915 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 129

On to step 8:
If we divide 129 by 129, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 542671.0
Subtracting 129 from 129 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 129, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 542671.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 129 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 542671.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 542671.0 with a remainder of 0.0.
