We divide 670519 by 45
The aim is to understand the frequency of 45 in 670519.

Advancing to step 1:
6 divided by 45 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 45

Moving on to step 2:
45 can be fit into 67 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 67 to get 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 45

Step 3:
220 divided by 45 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 180 away from 220, we end up with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 45

On to step 4:
45 goes into 405 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Subtract 405 from 405 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 45

Step 5:
1 divided by 45 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1490.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 45

On to step 6:
45 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 14900.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 45 fits into 190 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 14900.4
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 14900.42
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 45 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 14900.422
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 14900.422 and a remainder of 0.001.
