We look at the division of 18377377 by 144 
Our goal is to divide 18377377 by 144.

On to step 1:
The number 144 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 144

Advancing to step 2:
144 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 144

Step 3:
The number 144 fits into 183 1 times, leaving a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 144 from 183 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 144

On to step 4:
If we divide 397 by 144, we get 2 and a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 288 away from 397, we end up with 109.
Include the next digit (7) from the dividend after 109, then repeat: 1097 / 144

Going ahead to step 5:
When dividing 1097 by 144, we get 7 with a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 127.0
The remainder is 89 after subtracting 1008 from 1097.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 144

On to step 6:
If we divide 893 by 144, we get 6 and a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 1276.0
Subtracting 864 from 893 leaves us with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 144

Moving on to step 7:
144 goes into 297 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12762.0
Subtract 288 from 297 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 144

On to step 8:
The number 144 fits into 97 0 times, leaving a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 127620.0
If we subtract 0 from 97, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 9:
The number 144 fits into 970 6 times, leaving a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 127620.6
Subtracting 864 from 970 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
When dividing 1060 by 144, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 127620.67
Subtracting 1008 from 1060 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 144, we get 3 with a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 127620.673
Subtracting 432 from 520 leaves us 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.

Moving on to step 12:
144 can be fit into 880 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 127620.6736
If we take 864 away from 880, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 144 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 127620.67361
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
If we divide 160 by 144, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 127620.673611
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 127620.673611 and a remainder of 1.6e-06.
