216935 divided by 77 
The aim is to understand the frequency of 77 in 216935.

Advancing to step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 77

On to step 2:
77 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 77

On to step 3:
If we divide 216 by 77, we get 2 and a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 154 away from 216, we end up with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 77

Step 4:
77 goes into 629 8 times with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 616 away from 629, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 77

Going ahead to step 5:
When dividing 133 by 77, we get 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Deduct 77 from 133 and we're left with 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 77

Let's proceed to step 6:
When dividing 565 by 77, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 2817.0
Subtract 539 from 565 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
77 can be fit into 260 3 times, resulting in a remainder of 29.
The next digit of our result is 3. 
Result so far: 2817.3
If we subtract 231 from 260, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
77 goes into 290 3 times with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 2817.33
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 2817.33 with a remainder of 0.059.
