70303181 divided by 129 
We want to divide 70303181 by 129.

Moving on to step 1:
7 divided by 129 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
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

Step 2:
70 divided by 129 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 129

Going ahead to step 3:
703 divided by 129 is 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 645 from 703 to get 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 129

Going ahead to step 4:
When dividing 580 by 129, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 516 from 580, we get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 129

Let's proceed to step 5:
The number 129 fits into 643 4 times, leaving a remainder of 127.
Use 4 as the next digit of our solution. 
Result so far: 544.0
Subtracting 516 from 643 leaves us with 127.
Take the next digit (1) from the dividend and append it to 127, then repeat: 1271 / 129

On to step 6:
129 can be fit into 1271 9 times, resulting in a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 5449.0
If we subtract 1161 from 1271, we get 110.
Grab the next digit (8) from the dividend, add it to 110, then carry on: 1108 / 129

Moving on to step 7:
If we divide 1108 by 129, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 54498.0
If we take 1032 away from 1108, we end up with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 129

Moving on to step 8:
When dividing 761 by 129, we get 5 with a remainder of 116.
The next digit of our result is 5. 
Result so far: 544985.0
Subtracting 645 from 761 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
1160 divided by 129 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 544985.8
If we take 1032 away from 1160, 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 10:
1280 divided by 129 is 9 with a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 544985.89
Deduct 1161 from 1280 and we're left 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 11:
The number 129 fits into 1190 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 544985.899
The remainder is 29 after subtracting 1161 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 544985.899 with a balance of 0.0029.
