We're dividing 71539083 by 129 
We want to figure out the number of times 71539083 can be divided by 129.

Going ahead to step 1:
7 divided by 129 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 129

Moving on to step 2:
129 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 129

Going ahead to step 3:
If we divide 715 by 129, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 645 from 715 and we're left with 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 129

Moving on to step 4:
If we divide 703 by 129, we get 5 and a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 645 from 703 and we're left with 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 129

Moving on to step 5:
129 goes into 589 4 times with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 554.0
If we take 516 away from 589, we end up with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 129

Let's proceed to step 6:
129 can be fit into 730 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 5545.0
Subtracting 645 from 730 leaves us with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 129

Going ahead to step 7:
858 divided by 129 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 55456.0
If we take 774 away from 858, we end up with 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 129

Let's proceed to step 8:
129 goes into 843 6 times with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 554566.0
If we subtract 774 from 843, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
690 divided by 129 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 554566.5
The remainder is 45 after subtracting 645 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
450 divided by 129 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 554566.53
Subtract 387 from 450 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
630 divided by 129 is 4 with a remainder of 114.
The next digit of our result is 4. 
Result so far: 554566.534
If we take 516 away from 630, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 12:
129 can be fit into 1140 8 times, resulting in a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 554566.5348
Deduct 1032 from 1140 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
When dividing 1080 by 129, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 554566.53488
Subtract 1032 from 1080 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 554566.53488 and a remainder of 4.8e-05.
