We divide 218918 by 77
The aim is to understand the frequency of 77 in 218918.

Let's proceed to step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 77

Step 2:
If we divide 21 by 77, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 77

Advancing to step 3:
The number 77 fits into 218 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 154 from 218, we get 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 77

Step 4:
77 can be fit into 649 8 times, resulting in a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 33 after subtracting 616 from 649.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 77

Step 5:
331 divided by 77 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 284.0
Subtracting 308 from 331 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 77

Step 6:
77 can be fit into 238 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 2843.0
Deduct 231 from 238 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 77, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2843.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 2843.09
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 77, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2843.09
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 77 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 2843.0909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
The number 77 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 2843.0909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
77 goes into 700 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 2843.090909
Deduct 693 from 700 and we're left with 7.
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:
When dividing 70 by 77, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 2843.090909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2843.09090909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 2843.09090909, with a leftover of 7e-09.
