Let's divide 58587062 by 144
The aim is to understand the frequency of 144 in 58587062.

On to step 1:
144 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 144

Moving on to step 2:
144 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 144

Going ahead to step 3:
If we divide 585 by 144, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 9 after subtracting 576 from 585.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 144

Step 4:
144 goes into 98 0 times with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 98 after subtracting 0 from 98.
Take the next digit (7) from the dividend and append it to 98, then repeat: 987 / 144

Step 5:
If we divide 987 by 144, we get 6 and a remainder of 123.
The next digit of our result is 6. 
Result so far: 406.0
Subtract 864 from 987 to get 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 144

Advancing to step 6:
When dividing 1230 by 144, we get 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 4068.0
Subtracting 1152 from 1230 leaves us with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 144

Moving on to step 7:
144 can be fit into 786 5 times, resulting in a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 40685.0
Deduct 720 from 786 and we're left with 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 144

On to step 8:
The number 144 fits into 662 4 times, leaving a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 406854.0
The remainder is 86 after subtracting 576 from 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
144 can be fit into 860 5 times, resulting in a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 406854.5
If we subtract 720 from 860, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
The number 144 fits into 1400 9 times, leaving a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 406854.59
If we subtract 1296 from 1400, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
The number 144 fits into 1040 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 406854.597
If we take 1008 away from 1040, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
144 goes into 320 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 406854.5972
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
If we divide 320 by 144, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 406854.59722
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 406854.59722 and a remainder of 3.2e-05.
