We look at the division of 29121309 by 159 
We want to divide 29121309 by 159.

Advancing to step 1:
The number 159 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 159

Step 2:
The number 159 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 159

Let's proceed to step 3:
The number 159 fits into 291 1 times, leaving a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 159 from 291 leaves us with 132.
Bring next digit (2) of the dividend behind the 132 and repeat the process: 1322 / 159

Going ahead to step 4:
The number 159 fits into 1322 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 1272 from 1322 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 159

Step 5:
The number 159 fits into 501 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 183.0
Subtracting 477 from 501 leaves us with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 159

Let's proceed to step 6:
159 can be fit into 243 1 times, resulting in a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 1831.0
Subtracting 159 from 243 leaves us with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 159

Step 7:
When dividing 840 by 159, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 18315.0
Subtracting 795 from 840 leaves us with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 159

Step 8:
159 goes into 459 2 times with a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 183152.0
Subtract 318 from 459 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 9:
The number 159 fits into 1410 8 times, leaving a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 183152.8
The remainder is 138 after subtracting 1272 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
1380 divided by 159 is 8 with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 183152.88
Subtract 1272 from 1380 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 183152.88, with a leftover of 0.108.
