31236017 ÷ 143 
Our goal is to divide 31236017 by 143.

Let's proceed to step 1:
The number 143 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 143

Advancing to step 2:
If we divide 31 by 143, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 143

Let's proceed to step 3:
The number 143 fits into 312 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 286 from 312, we get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 143

On to step 4:
The number 143 fits into 263 1 times, leaving a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 143 from 263, we get 120.
Bring next digit (6) of the dividend behind the 120 and repeat the process: 1206 / 143

Advancing to step 5:
If we divide 1206 by 143, we get 8 and a remainder of 62.
The next digit of our result is 8. 
Result so far: 218.0
The remainder is 62 after subtracting 1144 from 1206.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 143

Step 6:
If we divide 620 by 143, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 2184.0
If we subtract 572 from 620, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 143

Moving on to step 7:
143 can be fit into 481 3 times, resulting in a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 21843.0
If we take 429 away from 481, we end up with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 143

Advancing to step 8:
When dividing 527 by 143, we get 3 with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 218433.0
Subtracting 429 from 527 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
143 goes into 980 6 times with a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 218433.6
Deduct 858 from 980 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
When dividing 1220 by 143, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 218433.68
Subtracting 1144 from 1220 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 143 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 218433.685
If we take 715 away from 760, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
143 goes into 450 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 218433.6853
Deduct 429 from 450 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
143 goes into 210 1 times with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 218433.68531
Subtract 143 from 210 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
If we divide 670 by 143, we get 4 and a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 218433.685314
Subtract 572 from 670 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
143 can be fit into 980 6 times, resulting in a remainder of 122.
The next digit of our result is 6. 
Result so far: 218433.6853146
If we subtract 858 from 980, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 16:
143 goes into 1220 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 218433.68531468
If we subtract 1144 from 1220, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 218433.68531468 with a balance of 7.6e-08.
