We're dividing 40788440 by 990 
The aim is to understand the frequency of 990 in 40788440.

Going ahead to step 1:
The number 990 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 990

Going ahead to step 2:
When dividing 40 by 990, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 990

Let's proceed to step 3:
990 can be fit into 407 0 times, resulting in a remainder of 407.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 407 and we're left with 407.
Append the next digit (8) from the dividend to 407 and continue with: 4078 / 990

Moving on to step 4:
4078 divided by 990 is 4 with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3960 from 4078, we get 118.
Take the next digit (8) from the dividend and append it to 118, then repeat: 1188 / 990

Let's proceed to step 5:
1188 divided by 990 is 1 with a remainder of 198.
The next digit of our result is 1. 
Result so far: 41.0
If we take 990 away from 1188, we end up with 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 990

Moving on to step 6:
If we divide 1984 by 990, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 412.0
Subtracting 1980 from 1984 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 990

Going ahead to step 7:
44 divided by 990 is 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 4120.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 990

On to step 8:
440 divided by 990 is 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 41200.0
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
4400 divided by 990 is 4 with a remainder of 440.
Put 4 as the next digit of the answer. 
Result so far: 41200.4
Subtracting 3960 from 4400 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 10:
990 goes into 4400 4 times with a remainder of 440.
Put 4 as the next digit of the answer. 
Result so far: 41200.44
The remainder is 440 after subtracting 3960 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

After the division, we end up with 41200.44 and a remainder of 0.44.
