We look at the division of 18372518 by 753 
The aim is to understand the frequency of 753 in 18372518.

On to step 1:
1 divided by 753 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 753

Moving on to step 2:
753 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 753

Step 3:
If we divide 183 by 753, we get 0 and a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 183 leaves us with 183.
Append the next digit (7) from the dividend to 183 and continue with: 1837 / 753

Moving on to step 4:
If we divide 1837 by 753, we get 2 and a remainder of 331.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1506 from 1837, we get 331.
Fetch the next digit (2) from the dividend, attach it to 331 and continue: 3312 / 753

On to step 5:
3312 divided by 753 is 4 with a remainder of 300.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 300 after subtracting 3012 from 3312.
Fetch the next digit (5) from the dividend, attach it to 300 and continue: 3005 / 753

Going ahead to step 6:
3005 divided by 753 is 3 with a remainder of 746.
Write down 3 as next digit of the result. 
Result so far: 243.0
If we subtract 2259 from 3005, we get 746.
Include the next digit (1) from the dividend after 746, then repeat: 7461 / 753

On to step 7:
When dividing 7461 by 753, we get 9 with a remainder of 684.
Put 9 as the next digit of the answer. 
Result so far: 2439.0
Deduct 6777 from 7461 and we're left with 684.
Bring next digit (8) of the dividend behind the 684 and repeat the process: 6848 / 753

Advancing to step 8:
The number 753 fits into 6848 9 times, leaving a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 24399.0
If we take 6777 away from 6848, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
753 can be fit into 710 0 times, resulting in a remainder of 710.
Put 0 as the next digit of the answer. 
Result so far: 24399.0
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 10:
The number 753 fits into 7100 9 times, leaving a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 24399.09
Deduct 6777 from 7100 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 11:
When dividing 3230 by 753, we get 4 with a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 24399.094
If we subtract 3012 from 3230, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
If we divide 2180 by 753, we get 2 and a remainder of 674.
Record the quotient 2 as the next digit in the result. 
Result so far: 24399.0942
Subtracting 1506 from 2180 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Let's proceed to step 13:
If we divide 6740 by 753, we get 8 and a remainder of 716.
Use 8 as the next digit of our solution. 
Result so far: 24399.09428
The remainder is 716 after subtracting 6024 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Let's proceed to step 14:
When dividing 7160 by 753, we get 9 with a remainder of 383.
Write down 9 as next digit of the result. 
Result so far: 24399.094289
If we subtract 6777 from 7160, we get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 15:
3830 divided by 753 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 24399.0942895
If we take 3765 away from 3830, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 16:
The number 753 fits into 650 0 times, leaving a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 24399.0942895
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 24399.0942895, with a leftover of 6.5e-07.
