Let's divide 23259031 by 143
Our goal is to divide 23259031 by 143.

On to step 1:
143 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 143

Advancing to step 2:
23 divided by 143 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 143

On to step 3:
232 divided by 143 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 143 from 232 leaves us with 89.
Append the next digit (5) from the dividend to 89 and continue with: 895 / 143

On to step 4:
895 divided by 143 is 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 858 from 895 leaves us with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 143

Advancing to step 5:
379 divided by 143 is 2 with a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtracting 286 from 379 leaves us with 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 143

Step 6:
When dividing 930 by 143, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 1626.0
If we take 858 away from 930, we end up with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 143

Moving on to step 7:
143 can be fit into 723 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 16265.0
The remainder is 8 after subtracting 715 from 723.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 143

On to step 8:
When dividing 81 by 143, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 162650.0
The remainder is 81 after subtracting 0 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
The number 143 fits into 810 5 times, leaving a remainder of 95.
The next digit of our result is 5. 
Result so far: 162650.5
Subtract 715 from 810 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
143 goes into 950 6 times with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 162650.56
If we take 858 away from 950, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
143 goes into 920 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 162650.566
The remainder is 62 after subtracting 858 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 162650.566 with a remainder of 0.0062.
