We look at the division of 678805 by 89 
The aim is to understand the frequency of 89 in 678805.

Advancing to step 1:
When dividing 6 by 89, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 89

Going ahead to step 2:
If we divide 67 by 89, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 89

On to step 3:
678 divided by 89 is 7 with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 623 from 678 and we're left with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 89

Moving on to step 4:
The number 89 fits into 558 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 534 from 558 and we're left with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 89

On to step 5:
89 can be fit into 240 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 762.0
Deduct 178 from 240 and we're left with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 89

Step 6:
If we divide 625 by 89, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7627.0
Subtracting 623 from 625 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 89, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7627.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 89, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 7627.02
Deduct 178 from 200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 89 fits into 220 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 7627.022
If we take 178 away from 220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 7627.022, and the remainder is 0.0042.
