Let's divide 21440905 by 143
Let's see how many times 143 fits into 21440905.

On to step 1:
143 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 143

On to step 2:
143 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 143

Step 3:
143 can be fit into 214 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 143 from 214 to get 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 143

On to step 4:
143 goes into 714 4 times with a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 572 from 714 leaves us with 142.
Take the next digit (0) from the dividend and append it to 142, then repeat: 1420 / 143

Going ahead to step 5:
If we divide 1420 by 143, we get 9 and a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 149.0
The remainder is 133 after subtracting 1287 from 1420.
Fetch the next digit (9) from the dividend, attach it to 133 and continue: 1339 / 143

On to step 6:
1339 divided by 143 is 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 1499.0
Subtract 1287 from 1339 to get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 143

Advancing to step 7:
143 goes into 520 3 times with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 14993.0
Subtracting 429 from 520 leaves us with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 143

Advancing to step 8:
143 goes into 915 6 times with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 149936.0
Deduct 858 from 915 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
143 goes into 570 3 times with a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 149936.3
If we subtract 429 from 570, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 10:
143 goes into 1410 9 times with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 149936.39
The remainder is 123 after subtracting 1287 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 11:
1230 divided by 143 is 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 149936.398
Subtracting 1144 from 1230 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
If we divide 860 by 143, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 149936.3986
The remainder is 2 after subtracting 858 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
When dividing 20 by 143, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 149936.3986
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 143, we get 1 and a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 149936.398601
Deduct 143 from 200 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
When dividing 570 by 143, we get 3 with a remainder of 141.
The next digit of our result is 3. 
Result so far: 149936.3986013
If we take 429 away from 570, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 16:
When dividing 1410 by 143, we get 9 with a remainder of 123.
Write down 9 as next digit of the result. 
Result so far: 149936.39860139
The remainder is 123 after subtracting 1287 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final outcome is 149936.39860139, with a leftover of 1.23e-07.
