14991215 ÷ 143 
Let's see how many times 143 fits into 14991215.

Going ahead to step 1:
If we divide 1 by 143, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 143

Moving on to step 2:
143 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 143

Advancing to step 3:
If we divide 149 by 143, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 143 from 149.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 143

Going ahead to step 4:
143 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 69, we end up with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 143

Advancing to step 5:
143 goes into 691 4 times with a remainder of 119.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we subtract 572 from 691, we get 119.
Append the next digit (2) from the dividend to 119 and continue with: 1192 / 143

Let's proceed to step 6:
The number 143 fits into 1192 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1048.0
If we subtract 1144 from 1192, we get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 143

Advancing to step 7:
If we divide 481 by 143, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 10483.0
If we take 429 away from 481, we end up with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 143

Moving on to step 8:
If we divide 525 by 143, we get 3 and a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 104833.0
Subtracting 429 from 525 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
The number 143 fits into 960 6 times, leaving a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 104833.6
If we take 858 away from 960, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
If we divide 1020 by 143, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 104833.67
Subtracting 1001 from 1020 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
The number 143 fits into 190 1 times, leaving a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 104833.671
The remainder is 47 after subtracting 143 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
The number 143 fits into 470 3 times, leaving a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 104833.6713
If we subtract 429 from 470, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
The number 143 fits into 410 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 104833.67132
Subtract 286 from 410 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 14:
When dividing 1240 by 143, we get 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 104833.671328
Deduct 1144 from 1240 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 15:
143 goes into 960 6 times with a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 104833.6713286
Subtracting 858 from 960 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 16:
1020 divided by 143 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 104833.67132867
If we subtract 1001 from 1020, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 104833.67132867, with a leftover of 1.9e-08.
