Let's divide 983606 by 45
The aim is to understand the frequency of 45 in 983606.

Going ahead to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 45

On to step 2:
When dividing 98 by 45, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 90 from 98 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 45

Moving on to step 3:
45 can be fit into 83 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 45 from 83, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 45

Advancing to step 4:
When dividing 386 by 45, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 218.0
Subtracting 360 from 386 leaves us with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 45

Step 5:
45 can be fit into 260 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 2185.0
If we take 225 away from 260, we end up with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 45

On to step 6:
356 divided by 45 is 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 21857.0
If we subtract 315 from 356, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
45 can be fit into 410 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 21857.9
If we subtract 405 from 410, we 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.

On to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 21857.91
If we subtract 45 from 50, we 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.

On to step 9:
45 goes into 50 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 21857.911
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.

Our division results in 21857.911 with a remaining 0.0005.
