We look at the division of 2349645 by 745 
The aim is to understand the frequency of 745 in 2349645.

Advancing to step 1:
745 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 745

Let's proceed to step 2:
23 divided by 745 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 745

Going ahead to step 3:
745 can be fit into 234 0 times, resulting in a remainder of 234.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 234, we get 234.
Grab the next digit (9) from the dividend, add it to 234, then carry on: 2349 / 745

Let's proceed to step 4:
The number 745 fits into 2349 3 times, leaving a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2235 from 2349 and we're left with 114.
Append the next digit (6) from the dividend to 114 and continue with: 1146 / 745

Step 5:
If we divide 1146 by 745, we get 1 and a remainder of 401.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 745 from 1146 and we're left with 401.
Take the next digit (4) from the dividend and append it to 401, then repeat: 4014 / 745

Advancing to step 6:
When dividing 4014 by 745, we get 5 with a remainder of 289.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtracting 3725 from 4014 leaves us with 289.
Append the next digit (5) from the dividend to 289 and continue with: 2895 / 745

Moving on to step 7:
745 can be fit into 2895 3 times, resulting in a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 3153.0
The remainder is 660 after subtracting 2235 from 2895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 8:
6600 divided by 745 is 8 with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 3153.8
If we take 5960 away from 6600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 9:
The number 745 fits into 6400 8 times, leaving a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 3153.88
Subtracting 5960 from 6400 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 3153.88 with a remaining 0.44.
