Let's divide 31302505 by 159
Our goal is to divide 31302505 by 159.

Let's proceed to step 1:
When dividing 3 by 159, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 159

Going ahead to step 2:
159 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 159

Advancing to step 3:
313 divided by 159 is 1 with a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 159 from 313 leaves us with 154.
Grab the next digit (0) from the dividend, add it to 154, then carry on: 1540 / 159

Advancing to step 4:
When dividing 1540 by 159, we get 9 with a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 1431 from 1540 leaves us with 109.
Bring next digit (2) of the dividend behind the 109 and repeat the process: 1092 / 159

On to step 5:
When dividing 1092 by 159, we get 6 with a remainder of 138.
The next digit of our result is 6. 
Result so far: 196.0
If we take 954 away from 1092, we end up with 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 159

Step 6:
When dividing 1385 by 159, we get 8 with a remainder of 113.
Use 8 as the next digit of our solution. 
Result so far: 1968.0
If we take 1272 away from 1385, we end up with 113.
Fetch the next digit (0) from the dividend, attach it to 113 and continue: 1130 / 159

On to step 7:
The number 159 fits into 1130 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 19687.0
Subtracting 1113 from 1130 leaves us with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 159

Let's proceed to step 8:
When dividing 175 by 159, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 196871.0
The remainder is 16 after subtracting 159 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 159, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 196871.1
Subtracting 159 from 160 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
When dividing 10 by 159, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 196871.1
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
159 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 196871.1
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 196871.1 and a remainder of 0.01.
