We divide 87869 by 45
The aim is to understand the frequency of 45 in 87869.

Let's proceed to step 1:
45 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 45

Advancing to step 2:
45 goes into 87 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 87, we get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 45

On to step 3:
428 divided by 45 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 23 after subtracting 405 from 428.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 45

On to step 4:
45 can be fit into 236 5 times, resulting in a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
The remainder is 11 after subtracting 225 from 236.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 45

Going ahead to step 5:
When dividing 119 by 45, we get 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 1952.0
If we take 90 away from 119, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 6:
The number 45 fits into 290 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1952.6
If we subtract 270 from 290, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 45, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1952.64
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1952.644
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1952.644 and a remainder of 0.002.
