We look at the division of 499098 by 40 
The aim is to understand the frequency of 40 in 499098.

Let's proceed to step 1:
4 divided by 40 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 40

Advancing to step 2:
40 goes into 49 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 9 after subtracting 40 from 49.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 40

On to step 3:
When dividing 99 by 40, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 80 from 99 to get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 40

Going ahead to step 4:
190 divided by 40 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Deduct 160 from 190 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 40

Moving on to step 5:
309 divided by 40 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1247.0
Subtracting 280 from 309 leaves us with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 40

Let's proceed to step 6:
40 can be fit into 298 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 12477.0
Subtracting 280 from 298 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 40 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 12477.4
The remainder is 20 after subtracting 160 from 180.
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 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12477.45
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12477.45
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12477.45
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12477.45, with a leftover of 0.0.
