Let's divide 453109 by 77
The aim is to understand the frequency of 77 in 453109.

On to step 1:
If we divide 4 by 77, we get 0 and 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.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 77

Going ahead to step 3:
The number 77 fits into 453 5 times, leaving a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 385 from 453 and we're left with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 77

Moving on to step 4:
681 divided by 77 is 8 with a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we subtract 616 from 681, we get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 77

Moving on to step 5:
650 divided by 77 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 588.0
If we take 616 away from 650, we end up with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 77

On to step 6:
77 goes into 349 4 times with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 5884.0
If we take 308 away from 349, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
410 divided by 77 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5884.5
The remainder is 25 after subtracting 385 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
The number 77 fits into 250 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 5884.53
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
If we divide 190 by 77, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 5884.532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
77 can be fit into 360 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 5884.5324
Subtract 308 from 360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
When dividing 520 by 77, we get 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 5884.53246
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
77 goes into 580 7 times with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 5884.532467
Deduct 539 from 580 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
When dividing 410 by 77, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5884.5324675
If we take 385 away from 410, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
77 can be fit into 250 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 5884.53246753
If we subtract 231 from 250, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 5884.53246753, with a leftover of 1.9e-08.
