We're dividing 85507834 by 144 
The aim is to understand the frequency of 144 in 85507834.

On to step 1:
The number 144 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 144

Step 2:
When dividing 85 by 144, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 144

Advancing to step 3:
144 goes into 855 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 720 from 855 leaves us with 135.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 144

On to step 4:
When dividing 1350 by 144, we get 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtract 1296 from 1350 to get 54.
Take the next digit (7) from the dividend and append it to 54, then repeat: 547 / 144

Going ahead to step 5:
547 divided by 144 is 3 with a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.0
The remainder is 115 after subtracting 432 from 547.
Grab the next digit (8) from the dividend, add it to 115, then carry on: 1158 / 144

On to step 6:
144 goes into 1158 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 5938.0
Deduct 1152 from 1158 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 144

Advancing to step 7:
144 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 59380.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 144

Step 8:
144 can be fit into 634 4 times, resulting in a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 593804.0
Subtract 576 from 634 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
If we divide 580 by 144, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 593804.4
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 144 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 593804.4
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
144 goes into 400 2 times with a remainder of 112.
The next digit of our result is 2. 
Result so far: 593804.402
The remainder is 112 after subtracting 288 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
If we divide 1120 by 144, we get 7 and a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 593804.4027
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
The number 144 fits into 1120 7 times, leaving a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 593804.40277
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Our division results in 593804.40277 with a remaining 0.000112.
