We look at the division of 81143227 by 144 
We want to divide 81143227 by 144.

Going ahead to step 1:
The number 144 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 144

Moving on to step 2:
If we divide 81 by 144, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 144

Step 3:
144 can be fit into 811 5 times, resulting in a remainder of 91.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 91 after subtracting 720 from 811.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 144

Going ahead to step 4:
914 divided by 144 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 864 from 914 and we're left with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 144

Let's proceed to step 5:
503 divided by 144 is 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 563.0
Subtracting 432 from 503 leaves us with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 144

Advancing to step 6:
The number 144 fits into 712 4 times, leaving a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 5634.0
If we take 576 away from 712, we end up with 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 144

On to step 7:
1362 divided by 144 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 56349.0
If we take 1296 away from 1362, we end up with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 144

Let's proceed to step 8:
144 can be fit into 667 4 times, resulting in a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 563494.0
If we subtract 576 from 667, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
When dividing 910 by 144, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 563494.6
The remainder is 46 after subtracting 864 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
144 goes into 460 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 563494.63
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
144 goes into 280 1 times with a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 563494.631
Subtracting 144 from 280 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 12:
When dividing 1360 by 144, we get 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 563494.6319
If we subtract 1296 from 1360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
If we divide 640 by 144, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 563494.63194
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
640 divided by 144 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 563494.631944
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 563494.631944, with a leftover of 6.4e-06.
