We're dividing 14598990 by 143 
Our goal is to divide 14598990 by 143.

On to step 1:
When dividing 1 by 143, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 143

On to step 2:
When dividing 14 by 143, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 143

Let's proceed to step 3:
If we divide 145 by 143, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 143 from 145 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 143

On to step 4:
If we divide 29 by 143, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 143

Advancing to step 5:
143 can be fit into 298 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 12 after subtracting 286 from 298.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 143

Going ahead to step 6:
143 can be fit into 129 0 times, resulting in a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 1020.0
The remainder is 129 after subtracting 0 from 129.
Fetch the next digit (9) from the dividend, attach it to 129 and continue: 1299 / 143

Going ahead to step 7:
143 goes into 1299 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 10209.0
The remainder is 12 after subtracting 1287 from 1299.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 143

Step 8:
143 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 102090.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
1200 divided by 143 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 102090.8
Subtract 1144 from 1200 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
If we divide 560 by 143, we get 3 and a remainder of 131.
The next digit of our result is 3. 
Result so far: 102090.83
The remainder is 131 after subtracting 429 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 11:
1310 divided by 143 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 102090.839
If we take 1287 away from 1310, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
The number 143 fits into 230 1 times, leaving a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 102090.8391
Deduct 143 from 230 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 13:
If we divide 870 by 143, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 102090.83916
If we take 858 away from 870, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
The number 143 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 102090.83916
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
The number 143 fits into 1200 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 102090.8391608
If we subtract 1144 from 1200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
When dividing 560 by 143, we get 3 with a remainder of 131.
The next digit of our result is 3. 
Result so far: 102090.83916083
If we take 429 away from 560, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final outcome is 102090.83916083, with a leftover of 1.31e-07.
