We look at the division of 12515289 by 753 
The aim is to understand the frequency of 753 in 12515289.

Step 1:
The number 753 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 753

Advancing to step 2:
The number 753 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 753

Going ahead to step 3:
753 can be fit into 125 0 times, resulting in a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 753

Going ahead to step 4:
753 can be fit into 1251 1 times, resulting in a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 498 after subtracting 753 from 1251.
Grab the next digit (5) from the dividend, add it to 498, then carry on: 4985 / 753

Advancing to step 5:
The number 753 fits into 4985 6 times, leaving a remainder of 467.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 4518 from 4985 and we're left with 467.
Include the next digit (2) from the dividend after 467, then repeat: 4672 / 753

Let's proceed to step 6:
When dividing 4672 by 753, we get 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
The remainder is 154 after subtracting 4518 from 4672.
Append the next digit (8) from the dividend to 154 and continue with: 1548 / 753

Going ahead to step 7:
When dividing 1548 by 753, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 1662.0
If we take 1506 away from 1548, we end up with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 753

Moving on to step 8:
When dividing 429 by 753, we get 0 with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 16620.0
The remainder is 429 after subtracting 0 from 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
753 can be fit into 4290 5 times, resulting in a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 16620.5
If we subtract 3765 from 4290, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 10:
If we divide 5250 by 753, we get 6 and a remainder of 732.
Use 6 as the next digit of our solution. 
Result so far: 16620.56
The remainder is 732 after subtracting 4518 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Moving on to step 11:
753 can be fit into 7320 9 times, resulting in a remainder of 543.
Write down 9 as next digit of the result. 
Result so far: 16620.569
If we subtract 6777 from 7320, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Moving on to step 12:
5430 divided by 753 is 7 with a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 16620.5697
If we take 5271 away from 5430, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 13:
753 can be fit into 1590 2 times, resulting in a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 16620.56972
The remainder is 84 after subtracting 1506 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
753 can be fit into 840 1 times, resulting in a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 16620.569721
Deduct 753 from 840 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 15:
870 divided by 753 is 1 with a remainder of 117.
The number 1 becomes the next digit in our result. 
Result so far: 16620.5697211
Subtracting 753 from 870 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

In conclusion, the division gives 16620.5697211 with a balance of 1.17e-06.
