We divide 73558439 by 909
The aim is to understand the frequency of 909 in 73558439.

Moving on to step 1:
7 divided by 909 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 909

On to step 2:
When dividing 73 by 909, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 909

Advancing to step 3:
If we divide 735 by 909, we get 0 and a remainder of 735.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 735 after subtracting 0 from 735.
Include the next digit (5) from the dividend after 735, then repeat: 7355 / 909

Step 4:
If we divide 7355 by 909, we get 8 and a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7272 from 7355, we get 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 909

Moving on to step 5:
The number 909 fits into 838 0 times, leaving a remainder of 838.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 838 leaves us with 838.
Bring next digit (4) of the dividend behind the 838 and repeat the process: 8384 / 909

On to step 6:
8384 divided by 909 is 9 with a remainder of 203.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we subtract 8181 from 8384, we get 203.
Take the next digit (3) from the dividend and append it to 203, then repeat: 2033 / 909

Moving on to step 7:
When dividing 2033 by 909, we get 2 with a remainder of 215.
The next digit of our result is 2. 
Result so far: 8092.0
Subtract 1818 from 2033 to get 215.
Bring next digit (9) of the dividend behind the 215 and repeat the process: 2159 / 909

Step 8:
909 can be fit into 2159 2 times, resulting in a remainder of 341.
Use 2 as the next digit of our solution. 
Result so far: 80922.0
If we take 1818 away from 2159, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
The number 909 fits into 3410 3 times, leaving a remainder of 683.
Write down 3 as next digit of the result. 
Result so far: 80922.3
If we subtract 2727 from 3410, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Step 10:
If we divide 6830 by 909, we get 7 and a remainder of 467.
The next digit of our result is 7. 
Result so far: 80922.37
Subtracting 6363 from 6830 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 11:
The number 909 fits into 4670 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 80922.375
Subtract 4545 from 4670 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
909 can be fit into 1250 1 times, resulting in a remainder of 341.
Use 1 as the next digit of our solution. 
Result so far: 80922.3751
If we take 909 away from 1250, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 13:
909 can be fit into 3410 3 times, resulting in a remainder of 683.
Record the quotient 3 as the next digit in the result. 
Result so far: 80922.37513
If we subtract 2727 from 3410, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 14:
The number 909 fits into 6830 7 times, leaving a remainder of 467.
The next digit of our result is 7. 
Result so far: 80922.375137
If we take 6363 away from 6830, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 15:
When dividing 4670 by 909, we get 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 80922.3751375
Subtracting 4545 from 4670 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
If we divide 1250 by 909, we get 1 and a remainder of 341.
Use 1 as the next digit of our solution. 
Result so far: 80922.37513751
Subtracting 909 from 1250 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The quotient of the division is 80922.37513751, and the remainder is 3.41e-07.
