We look at the division of 67379 by 45 
The aim is to understand the frequency of 45 in 67379.

Advancing to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 45

Going ahead to step 2:
If we divide 67 by 45, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 67, we end up with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 45

Going ahead to step 3:
The number 45 fits into 223 4 times, leaving a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 180 from 223 and we're left with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 45

Moving on to step 4:
437 divided by 45 is 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 149.0
Deduct 405 from 437 and we're left with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 45

On to step 5:
The number 45 fits into 329 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
The remainder is 14 after subtracting 315 from 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 6:
45 can be fit into 140 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1497.3
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1497.31
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1497.311
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1497.311, with a leftover of 0.0005.
