991086 divided by 40 
The aim is to understand the frequency of 40 in 991086.

Moving on to step 1:
40 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 40

Going ahead to step 2:
40 goes into 99 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 19 after subtracting 80 from 99.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 40

Moving on to step 3:
If we divide 191 by 40, we get 4 and a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 160 from 191 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 40

Going ahead to step 4:
The number 40 fits into 310 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 247.0
Subtracting 280 from 310 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 40

Let's proceed to step 5:
If we divide 308 by 40, we get 7 and a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 2477.0
If we subtract 280 from 308, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 40

Moving on to step 6:
40 can be fit into 286 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 24777.0
Subtracting 280 from 286 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 40, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 24777.1
Subtract 40 from 60 to 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 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 24777.15
Subtract 200 from 200 to get 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:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24777.15
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24777.15
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 24777.15 with a balance of 0.0.
