5012135 ÷ 159 
We want to figure out the number of times 5012135 can be divided by 159.

Let's proceed to step 1:
If we divide 5 by 159, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 159

On to step 2:
159 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 159

Advancing to step 3:
159 can be fit into 501 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
If we take 477 away from 501, we end up with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 159

Step 4:
If we divide 242 by 159, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 159 from 242 and we're left with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 159

Going ahead to step 5:
159 goes into 831 5 times with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 315.0
The remainder is 36 after subtracting 795 from 831.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 159

Step 6:
159 goes into 363 2 times with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 3152.0
If we take 318 away from 363, we end up with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 159

Let's proceed to step 7:
159 can be fit into 455 2 times, resulting in a remainder of 137.
Write down 2 as next digit of the result. 
Result so far: 31522.0
Subtracting 318 from 455 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 8:
When dividing 1370 by 159, we get 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 31522.8
The remainder is 98 after subtracting 1272 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
980 divided by 159 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 31522.86
Subtract 954 from 980 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
If we divide 260 by 159, we get 1 and a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 31522.861
Subtracting 159 from 260 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 11:
159 goes into 1010 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 31522.8616
Subtract 954 from 1010 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
If we divide 560 by 159, we get 3 and a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 31522.86163
Deduct 477 from 560 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
159 goes into 830 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 31522.861635
Subtracting 795 from 830 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
If we divide 350 by 159, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 31522.8616352
Subtract 318 from 350 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 15:
159 goes into 320 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 31522.86163522
Subtracting 318 from 320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 31522.86163522 and a remainder of 2e-09.
