We look at the division of 26035575 by 990 
The aim is to understand the frequency of 990 in 26035575.

Going ahead to step 1:
When dividing 2 by 990, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 990

On to step 2:
When dividing 26 by 990, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 990

On to step 3:
990 can be fit into 260 0 times, resulting in a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 260 leaves us with 260.
Fetch the next digit (3) from the dividend, attach it to 260 and continue: 2603 / 990

Advancing to step 4:
When dividing 2603 by 990, we get 2 with a remainder of 623.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1980 from 2603, we get 623.
Append the next digit (5) from the dividend to 623 and continue with: 6235 / 990

Step 5:
When dividing 6235 by 990, we get 6 with a remainder of 295.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 5940 from 6235, we get 295.
Fetch the next digit (5) from the dividend, attach it to 295 and continue: 2955 / 990

Advancing to step 6:
If we divide 2955 by 990, we get 2 and a remainder of 975.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
The remainder is 975 after subtracting 1980 from 2955.
Append the next digit (7) from the dividend to 975 and continue with: 9757 / 990

Advancing to step 7:
990 goes into 9757 9 times with a remainder of 847.
Write down 9 as next digit of the result. 
Result so far: 2629.0
Deduct 8910 from 9757 and we're left with 847.
Fetch the next digit (5) from the dividend, attach it to 847 and continue: 8475 / 990

Step 8:
When dividing 8475 by 990, we get 8 with a remainder of 555.
The number 8 becomes the next digit in our result. 
Result so far: 26298.0
Subtracting 7920 from 8475 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 9:
When dividing 5550 by 990, we get 5 with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 26298.5
Subtract 4950 from 5550 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 10:
990 goes into 6000 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 26298.56
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 990, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 26298.56
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
The number 990 fits into 6000 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 26298.5606
If we subtract 5940 from 6000, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
When dividing 600 by 990, we get 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 26298.5606
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
6000 divided by 990 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 26298.560606
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
990 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 26298.560606
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
The number 990 fits into 6000 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 26298.56060606
If we take 5940 away from 6000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 26298.56060606 with a remainder of 6e-08.
