671432 divided by 45 
The aim is to understand the frequency of 45 in 671432.

Step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 45

On to step 2:
The number 45 fits into 67 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 67 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 45

Let's proceed to step 3:
45 goes into 221 4 times with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 41 after subtracting 180 from 221.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 45

Moving on to step 4:
45 can be fit into 414 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 9 after subtracting 405 from 414.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 45

Advancing to step 5:
45 can be fit into 93 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 1492.0
The remainder is 3 after subtracting 90 from 93.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 45

Moving on to step 6:
45 can be fit into 32 0 times, resulting in a remainder of 32.
The next digit of our result is 0. 
Result so far: 14920.0
Subtracting 0 from 32 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
The number 45 fits into 320 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 14920.7
Subtract 315 from 320 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.
Use 1 as the next digit of our solution. 
Result so far: 14920.71
Deduct 45 from 50 and we're left with 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 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 14920.711
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.

The quotient of the division is 14920.711, and the remainder is 0.0005.
