We're dividing 14450287 by 745 
The aim is to understand the frequency of 745 in 14450287.

On to step 1:
When dividing 1 by 745, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 745

Moving on to step 2:
When dividing 14 by 745, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 745

Advancing to step 3:
When dividing 144 by 745, we get 0 with a remainder of 144.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 144, we get 144.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 745

On to step 4:
1445 divided by 745 is 1 with a remainder of 700.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 745 from 1445 and we're left with 700.
Include the next digit (0) from the dividend after 700, then repeat: 7000 / 745

Advancing to step 5:
7000 divided by 745 is 9 with a remainder of 295.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 6705 away from 7000, we end up with 295.
Include the next digit (2) from the dividend after 295, then repeat: 2952 / 745

Let's proceed to step 6:
When dividing 2952 by 745, we get 3 with a remainder of 717.
Write down 3 as next digit of the result. 
Result so far: 193.0
If we take 2235 away from 2952, we end up with 717.
Take the next digit (8) from the dividend and append it to 717, then repeat: 7178 / 745

Going ahead to step 7:
When dividing 7178 by 745, we get 9 with a remainder of 473.
Use 9 as the next digit of our solution. 
Result so far: 1939.0
If we take 6705 away from 7178, we end up with 473.
Grab the next digit (7) from the dividend, add it to 473, then carry on: 4737 / 745

Let's proceed to step 8:
If we divide 4737 by 745, we get 6 and a remainder of 267.
Record the quotient 6 as the next digit in the result. 
Result so far: 19396.0
Deduct 4470 from 4737 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 9:
745 goes into 2670 3 times with a remainder of 435.
The number 3 becomes the next digit in our result. 
Result so far: 19396.3
Subtract 2235 from 2670 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 10:
4350 divided by 745 is 5 with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 19396.35
Subtract 3725 from 4350 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 11:
The number 745 fits into 6250 8 times, leaving a remainder of 290.
Write down 8 as next digit of the result. 
Result so far: 19396.358
If we subtract 5960 from 6250, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 12:
745 goes into 2900 3 times with a remainder of 665.
The next digit of our result is 3. 
Result so far: 19396.3583
If we take 2235 away from 2900, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 13:
745 goes into 6650 8 times with a remainder of 690.
Put 8 as the next digit of the answer. 
Result so far: 19396.35838
Deduct 5960 from 6650 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 14:
6900 divided by 745 is 9 with a remainder of 195.
The next digit of our result is 9. 
Result so far: 19396.358389
Subtracting 6705 from 6900 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 15:
If we divide 1950 by 745, we get 2 and a remainder of 460.
Put 2 as the next digit of the answer. 
Result so far: 19396.3583892
Deduct 1490 from 1950 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 16:
745 can be fit into 4600 6 times, resulting in a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 19396.35838926
Subtracting 4470 from 4600 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 19396.35838926, with a leftover of 1.3e-07.
