Let's divide 981832 by 45
The aim is to understand the frequency of 45 in 981832.

Going ahead to step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 45

Moving on to step 2:
98 divided by 45 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 90 away from 98, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

Let's proceed to step 3:
When dividing 81 by 45, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 45 from 81, we get 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 45

Going ahead to step 4:
368 divided by 45 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Subtract 360 from 368 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 45

Advancing to step 5:
83 divided by 45 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 2181.0
If we subtract 45 from 83, we get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 45

Let's proceed to step 6:
45 goes into 382 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 21818.0
If we take 360 away from 382, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 45, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 21818.4
Deduct 180 from 220 and we're left 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.

Advancing to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 21818.48
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.

Advancing to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 21818.488
Subtract 360 from 400 to 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.

The final result is 21818.488 with a remainder of 0.004.
