Let's divide 769673 by 77
The aim is to understand the frequency of 77 in 769673.

Let's proceed to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 77

On to step 2:
If we divide 76 by 77, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 77

On to step 3:
If we divide 769 by 77, we get 9 and a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 769, we end up with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 77

Let's proceed to step 4:
When dividing 766 by 77, we get 9 with a remainder of 73.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 693 from 766 leaves us with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 77

Moving on to step 5:
77 goes into 737 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtracting 693 from 737 leaves us with 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 77

Step 6:
The number 77 fits into 443 5 times, leaving a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 9995.0
If we subtract 385 from 443, we 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.

On to step 7:
If we divide 580 by 77, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 9995.7
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 8:
77 can be fit into 410 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 9995.75
If we subtract 385 from 410, we get 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 9:
77 can be fit into 250 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 9995.753
The remainder is 19 after subtracting 231 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
77 goes into 190 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 9995.7532
Subtracting 154 from 190 leaves us with 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 11:
The number 77 fits into 360 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 9995.75324
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.

Advancing to step 12:
If we divide 520 by 77, we get 6 and a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 9995.753246
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
If we divide 580 by 77, we get 7 and a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 9995.7532467
The remainder is 41 after subtracting 539 from 580.
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 14:
77 can be fit into 410 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9995.75324675
Subtract 385 from 410 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 9995.75324675 with a remainder of 2.5e-08.
