We divide 1623134 by 144
The aim is to understand the frequency of 144 in 1623134.

Step 1:
1 divided by 144 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 144

On to step 2:
The number 144 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 144

Advancing to step 3:
If we divide 162 by 144, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 144 from 162 to get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 144

On to step 4:
If we divide 183 by 144, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 144 from 183 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 144

On to step 5:
144 goes into 391 2 times with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 103 after subtracting 288 from 391.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 144

Advancing to step 6:
If we divide 1033 by 144, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 1127.0
Deduct 1008 from 1033 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 144

Moving on to step 7:
If we divide 254 by 144, we get 1 and a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 11271.0
Subtract 144 from 254 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 8:
When dividing 1100 by 144, we get 7 with a remainder of 92.
Write down 7 as next digit of the result. 
Result so far: 11271.7
Subtracting 1008 from 1100 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
920 divided by 144 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 11271.76
The remainder is 56 after subtracting 864 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
144 goes into 560 3 times with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 11271.763
If we take 432 away from 560, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 11:
1280 divided by 144 is 8 with a remainder of 128.
The next digit of our result is 8. 
Result so far: 11271.7638
If we take 1152 away from 1280, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
144 goes into 1280 8 times with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 11271.76388
Deduct 1152 from 1280 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 11271.76388 and a remainder of 0.000128.
