We divide 777435 by 89
The aim is to understand the frequency of 89 in 777435.

Advancing to step 1:
The number 89 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 89

On to step 2:
89 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 89

Going ahead to step 3:
89 can be fit into 777 8 times, resulting in a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 712 from 777, we get 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 89

On to step 4:
If we divide 654 by 89, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 623 from 654 to get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 89

Going ahead to step 5:
89 goes into 313 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
If we subtract 267 from 313, we get 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 89

Going ahead to step 6:
89 goes into 465 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 8735.0
Subtracting 445 from 465 leaves us 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 7:
200 divided by 89 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 8735.2
If we subtract 178 from 200, we get 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 8:
If we divide 220 by 89, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 8735.22
Deduct 178 from 220 and we're left 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 final result is 8735.22 with a remainder of 0.042.
