Let's divide 672893 by 45
The aim is to understand the frequency of 45 in 672893.

Going ahead to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 45

Advancing to step 2:
The number 45 fits into 67 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 22 after subtracting 45 from 67.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 45

Going ahead to step 3:
45 goes into 222 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 180 from 222 and we're left with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 45

Step 4:
The number 45 fits into 428 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Deduct 405 from 428 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Moving on to step 5:
45 goes into 239 5 times with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 1495.0
Subtract 225 from 239 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 45

Going ahead to step 6:
143 divided by 45 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 14953.0
Subtract 135 from 143 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 45 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 14953.1
If we subtract 45 from 80, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 14953.17
Subtracting 315 from 350 leaves us with 35.
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 9:
45 goes into 350 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 14953.177
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 14953.177, with a leftover of 0.0035.
