We're dividing 69588479 by 773 
The aim is to understand the frequency of 773 in 69588479.

On to step 1:
6 divided by 773 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 773

Going ahead to step 2:
When dividing 69 by 773, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 773

Let's proceed to step 3:
773 can be fit into 695 0 times, resulting in a remainder of 695.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 695 and we're left with 695.
Take the next digit (8) from the dividend and append it to 695, then repeat: 6958 / 773

Advancing to step 4:
6958 divided by 773 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 1 after subtracting 6957 from 6958.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 773

Step 5:
When dividing 18 by 773, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 18 to get 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 773

On to step 6:
773 goes into 184 0 times with a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
Subtracting 0 from 184 leaves us with 184.
Append the next digit (7) from the dividend to 184 and continue with: 1847 / 773

Step 7:
773 can be fit into 1847 2 times, resulting in a remainder of 301.
The next digit of our result is 2. 
Result so far: 9002.0
Subtracting 1546 from 1847 leaves us with 301.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 773

Advancing to step 8:
773 goes into 3019 3 times with a remainder of 700.
Put 3 as the next digit of the answer. 
Result so far: 90023.0
If we subtract 2319 from 3019, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 9:
773 goes into 7000 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 90023.9
If we subtract 6957 from 7000, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
773 can be fit into 430 0 times, resulting in a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 90023.9
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 11:
When dividing 4300 by 773, we get 5 with a remainder of 435.
The number 5 becomes the next digit in our result. 
Result so far: 90023.905
If we subtract 3865 from 4300, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 12:
If we divide 4350 by 773, we get 5 and a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 90023.9055
If we subtract 3865 from 4350, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Our division results in 90023.9055 with a remaining 0.00485.
