Let's divide 144960 by 57
The aim is to understand the frequency of 57 in 144960.

Advancing to step 1:
1 divided by 57 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 57

Moving on to step 2:
When dividing 14 by 57, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 57

Let's proceed to step 3:
The number 57 fits into 144 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 114 from 144 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 57

On to step 4:
The number 57 fits into 309 5 times, leaving a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 285 away from 309, we end up with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 57

Advancing to step 5:
57 goes into 246 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Subtracting 228 from 246 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 57

Moving on to step 6:
180 divided by 57 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 2543.0
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 57 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 2543.1
Subtracting 57 from 90 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
If we divide 330 by 57, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2543.15
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
If we divide 450 by 57, we get 7 and a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 2543.157
If we subtract 399 from 450, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
When dividing 510 by 57, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 2543.1578
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
When dividing 540 by 57, we get 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 2543.15789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
The number 57 fits into 270 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 2543.157894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
57 goes into 420 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 2543.1578947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
57 goes into 210 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 2543.15789473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 2543.15789473, and the remainder is 3.9e-08.
