Let's divide 221419 by 77
The aim is to understand the frequency of 77 in 221419.

Advancing 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.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 77

Advancing to step 2:
If we divide 22 by 77, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 77

Advancing to step 3:
If we divide 221 by 77, we get 2 and a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 154 from 221, we get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 77

Going ahead to step 4:
77 goes into 674 8 times with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 58 after subtracting 616 from 674.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 77

Step 5:
77 goes into 581 7 times with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 287.0
If we take 539 away from 581, we end up with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 77

Step 6:
77 can be fit into 429 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 2875.0
Subtracting 385 from 429 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
440 divided by 77 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 2875.5
The remainder is 55 after subtracting 385 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
77 can be fit into 550 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 2875.57
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
The number 77 fits into 110 1 times, leaving a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 2875.571
Deduct 77 from 110 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
77 can be fit into 330 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 2875.5714
Subtract 308 from 330 to 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.

On to step 11:
77 can be fit into 220 2 times, resulting in a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 2875.57142
If we take 154 away from 220, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
660 divided by 77 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 2875.571428
Subtracting 616 from 660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
77 can be fit into 440 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2875.5714285
Subtracting 385 from 440 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
The number 77 fits into 550 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 2875.57142857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 2875.57142857, with a leftover of 1.1e-08.
