We divide 343374 by 45
The aim is to understand the frequency of 45 in 343374.

Moving on to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 45

Moving on to step 2:
45 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 45

Going ahead to step 3:
343 divided by 45 is 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 315 from 343 to get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 45

Advancing to step 4:
45 can be fit into 283 6 times, resulting in a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 270 from 283 leaves us with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 45

On to step 5:
If we divide 137 by 45, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
Subtract 135 from 137 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 45

Step 6:
24 divided by 45 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 7630.0
Subtract 0 from 24 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
45 can be fit into 240 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 7630.5
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 7630.53
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 7630.533
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 7630.533 with a remainder of 0.0015.
