We're dividing 12739578 by 745 
The aim is to understand the frequency of 745 in 12739578.

Moving on to step 1:
When dividing 1 by 745, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 745

On to step 2:
745 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 745

Advancing to step 3:
If we divide 127 by 745, we get 0 and a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 745

On to step 4:
745 can be fit into 1273 1 times, resulting in a remainder of 528.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 745 from 1273 leaves us with 528.
Append the next digit (9) from the dividend to 528 and continue with: 5289 / 745

Moving on to step 5:
5289 divided by 745 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 74 after subtracting 5215 from 5289.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 745

Going ahead to step 6:
The number 745 fits into 745 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 171.0
Deduct 745 from 745 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 745

Step 7:
The number 745 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 1710.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 745

Step 8:
When dividing 78 by 745, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 17100.0
If we subtract 0 from 78, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
780 divided by 745 is 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 17100.1
The remainder is 35 after subtracting 745 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 745 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 17100.1
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
745 goes into 3500 4 times with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 17100.104
Subtract 2980 from 3500 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 12:
745 goes into 5200 6 times with a remainder of 730.
Put 6 as the next digit of the answer. 
Result so far: 17100.1046
Deduct 4470 from 5200 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Advancing to step 13:
745 goes into 7300 9 times with a remainder of 595.
Write down 9 as next digit of the result. 
Result so far: 17100.10469
If we take 6705 away from 7300, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 14:
5950 divided by 745 is 7 with a remainder of 735.
Write down 7 as next digit of the result. 
Result so far: 17100.104697
The remainder is 735 after subtracting 5215 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 15:
If we divide 7350 by 745, we get 9 and a remainder of 645.
The next digit of our result is 9. 
Result so far: 17100.1046979
If we subtract 6705 from 7350, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 16:
6450 divided by 745 is 8 with a remainder of 490.
The next digit of our result is 8. 
Result so far: 17100.10469798
If we take 5960 away from 6450, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 17100.10469798 with a balance of 4.9e-07.
