Let's divide 494671 by 45
The aim is to understand the frequency of 45 in 494671.

Step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 45

On to step 2:
45 goes into 49 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 49 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

On to step 3:
44 divided by 45 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 45

On to step 4:
If we divide 446 by 45, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 41 after subtracting 405 from 446.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 45

Going ahead to step 5:
The number 45 fits into 417 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 1099.0
Deduct 405 from 417 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 45

Going ahead to step 6:
If we divide 121 by 45, we get 2 and a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 10992.0
If we take 90 away from 121, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
If we divide 310 by 45, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 10992.6
The remainder is 40 after subtracting 270 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
45 goes into 400 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 10992.68
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 10992.688
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 10992.688 with a balance of 0.004.
