We divide 893491 by 45
The aim is to understand the frequency of 45 in 893491.

Advancing to step 1:
45 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 45

Step 2:
When dividing 89 by 45, we get 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 89 leaves us with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 45

Step 3:
The number 45 fits into 443 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 38 after subtracting 405 from 443.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 45

Going ahead to step 4:
If we divide 384 by 45, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 198.0
The remainder is 24 after subtracting 360 from 384.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 45

Moving on to step 5:
The number 45 fits into 249 5 times, leaving a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 1985.0
If we subtract 225 from 249, we get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 45

Advancing to step 6:
45 goes into 241 5 times with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 19855.0
Subtract 225 from 241 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 45, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 19855.3
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 19855.35
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 19855.355
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 19855.355 and a remainder of 0.0025.
