Let's divide 749670 by 77
The aim is to understand the frequency of 77 in 749670.

Moving on to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 77

On to step 2:
When dividing 74 by 77, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 77

Let's proceed to step 3:
When dividing 749 by 77, we get 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 749, we end up with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 77

Moving on to step 4:
When dividing 566 by 77, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 97.0
If we take 539 away from 566, we end up with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 77

Step 5:
The number 77 fits into 277 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 973.0
Subtract 231 from 277 to get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 77

Moving on to step 6:
If we divide 460 by 77, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 9735.0
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
750 divided by 77 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 9735.9
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
The number 77 fits into 570 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 9735.97
If we subtract 539 from 570, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
77 goes into 310 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 9735.974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9735.974
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 77, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 9735.97402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
77 goes into 460 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 9735.974025
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 9735.9740259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 14:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 9735.97402597
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 9735.97402597 and a remainder of 3.1e-08.
