We're dividing 80779099 by 897 
The aim is to understand the frequency of 897 in 80779099.

Going ahead to step 1:
8 divided by 897 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 897

Let's proceed to step 2:
897 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 897

Let's proceed to step 3:
When dividing 807 by 897, we get 0 with a remainder of 807.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 807, we get 807.
Bring next digit (7) of the dividend behind the 807 and repeat the process: 8077 / 897

Step 4:
897 goes into 8077 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8073 away from 8077, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 897

Step 5:
The number 897 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 49, we get 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 897

Step 6:
490 divided by 897 is 0 with a remainder of 490.
The next digit of our result is 0. 
Result so far: 900.0
If we take 0 away from 490, we end up with 490.
Append the next digit (9) from the dividend to 490 and continue with: 4909 / 897

Advancing to step 7:
The number 897 fits into 4909 5 times, leaving a remainder of 424.
The next digit of our result is 5. 
Result so far: 9005.0
The remainder is 424 after subtracting 4485 from 4909.
Append the next digit (9) from the dividend to 424 and continue with: 4249 / 897

Moving on to step 8:
When dividing 4249 by 897, we get 4 with a remainder of 661.
The number 4 becomes the next digit in our result. 
Result so far: 90054.0
Subtract 3588 from 4249 to get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Let's proceed to step 9:
When dividing 6610 by 897, we get 7 with a remainder of 331.
Put 7 as the next digit of the answer. 
Result so far: 90054.7
Deduct 6279 from 6610 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 10:
If we divide 3310 by 897, we get 3 and a remainder of 619.
The number 3 becomes the next digit in our result. 
Result so far: 90054.73
Subtract 2691 from 3310 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Moving on to step 11:
897 can be fit into 6190 6 times, resulting in a remainder of 808.
The number 6 becomes the next digit in our result. 
Result so far: 90054.736
The remainder is 808 after subtracting 5382 from 6190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Advancing to step 12:
The number 897 fits into 8080 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 90054.7369
The remainder is 7 after subtracting 8073 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
If we divide 70 by 897, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 90054.7369
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
When dividing 700 by 897, we get 0 with a remainder of 700.
The next digit of our result is 0. 
Result so far: 90054.7369
If we subtract 0 from 700, 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.

The final result is 90054.7369 with a remainder of 7e-05.
