We divide 757529 by 77
The aim is to understand the frequency of 77 in 757529.

Step 1:
77 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 77

Let's proceed to step 2:
When dividing 75 by 77, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 77

Step 3:
If we divide 757 by 77, we get 9 and a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 757, we end up with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 77

Moving on to step 4:
77 can be fit into 645 8 times, resulting in a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 616 from 645 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 77

On to step 5:
77 goes into 292 3 times with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 983.0
If we take 231 away from 292, we end up with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 77

Step 6:
619 divided by 77 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 9838.0
If we subtract 616 from 619, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
77 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9838.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 9838.03
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 9838.038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
When dividing 740 by 77, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 9838.0389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
When dividing 470 by 77, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 9838.03896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 77, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 9838.038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
77 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9838.038961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 77 is 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 9838.03896103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 9838.03896103, and the remainder is 6.9e-08.
