The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 143

On to step 2:
10 divided by 143 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 143

Going ahead to step 3:
The number 143 fits into 103 0 times, leaving a remainder of 103.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 103 after subtracting 0 from 103.
Append the next digit (3) from the dividend to 103 and continue with: 1033 / 143

Moving on to step 4:
When dividing 1033 by 143, we get 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 1001 from 1033 to get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 143

Moving on to step 5:
When dividing 323 by 143, we get 2 with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 286 from 323 to get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 143

Moving on to step 6:
The number 143 fits into 379 2 times, leaving a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 722.0
If we take 286 away from 379, we end up with 93.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 143

Advancing to step 7:
If we divide 938 by 143, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 7226.0
Subtract 858 from 938 to get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 143

Advancing to step 8:
143 can be fit into 803 5 times, resulting in a remainder of 88.
The number 5 becomes the next digit in our result. 
Result so far: 72265.0
If we subtract 715 from 803, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
880 divided by 143 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 72265.6
Subtracting 858 from 880 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
143 can be fit into 220 1 times, resulting in a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 72265.61
The remainder is 77 after subtracting 143 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 11:
The number 143 fits into 770 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 72265.615
Deduct 715 from 770 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
The number 143 fits into 550 3 times, leaving a remainder of 121.
The next digit of our result is 3. 
Result so far: 72265.6153
The remainder is 121 after subtracting 429 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 13:
If we divide 1210 by 143, we get 8 and a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 72265.61538
The remainder is 66 after subtracting 1144 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
660 divided by 143 is 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 72265.615384
If we take 572 away from 660, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
880 divided by 143 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 72265.6153846
If we subtract 858 from 880, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 16:
143 goes into 220 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 72265.61538461
Subtract 143 from 220 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The quotient of the division is 72265.61538461, and the remainder is 7.7e-08.
