453354 ÷ 77 
The aim is to understand the frequency of 77 in 453354.

Step 1:
4 divided by 77 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 77

Advancing to step 2:
The number 77 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 77

On to step 3:
77 goes into 453 5 times with a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 385 from 453, we get 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 77

Step 4:
683 divided by 77 is 8 with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 616 from 683 to get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 77

Advancing to step 5:
If we divide 675 by 77, we get 8 and a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 588.0
The remainder is 59 after subtracting 616 from 675.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 77

Let's proceed to step 6:
77 can be fit into 594 7 times, resulting in a remainder of 55.
The next digit of our result is 7. 
Result so far: 5887.0
Subtracting 539 from 594 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.

Advancing to step 7:
77 goes into 550 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 5887.7
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 8:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 5887.71
Subtracting 77 from 110 leaves us 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.

Going ahead to step 9:
330 divided by 77 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 5887.714
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.

Advancing to step 10:
The number 77 fits into 220 2 times, leaving a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 5887.7142
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 11:
77 goes into 660 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 5887.71428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 77, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5887.714285
If we take 385 away from 440, we end up 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.

Advancing to step 13:
550 divided by 77 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 5887.7142857
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.

Let's proceed to step 14:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 5887.71428571
If we take 77 away from 110, we end up 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.

The final outcome is 5887.71428571, with a leftover of 3.3e-08.
