We divide 17203475 by 145
The aim is to understand the frequency of 145 in 17203475.

Moving on to step 1:
1 divided by 145 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 145

Let's proceed to step 2:
If we divide 17 by 145, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 145

On to step 3:
172 divided by 145 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 27 after subtracting 145 from 172.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 145

Step 4:
If we divide 270 by 145, we get 1 and a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 145 from 270 to get 125.
Bring next digit (3) of the dividend behind the 125 and repeat the process: 1253 / 145

Step 5:
145 goes into 1253 8 times with a remainder of 93.
The next digit of our result is 8. 
Result so far: 118.0
Subtract 1160 from 1253 to get 93.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 145

Going ahead to step 6:
If we divide 934 by 145, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 1186.0
Subtracting 870 from 934 leaves us with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 145

Moving on to step 7:
The number 145 fits into 647 4 times, leaving a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 11864.0
If we subtract 580 from 647, we get 67.
Fetch the next digit (5) from the dividend, attach it to 67 and continue: 675 / 145

Going ahead to step 8:
When dividing 675 by 145, we get 4 with a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 118644.0
Subtract 580 from 675 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
950 divided by 145 is 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 118644.6
If we subtract 870 from 950, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
The number 145 fits into 800 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 118644.65
The remainder is 75 after subtracting 725 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
145 can be fit into 750 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 118644.655
Subtract 725 from 750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 118644.655 and a remainder of 0.0025.
