We divide 75767915 by 770
The aim is to understand the frequency of 770 in 75767915.

On to step 1:
If we divide 7 by 770, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 770

Step 2:
770 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 770

Advancing to step 3:
770 goes into 757 0 times with a remainder of 757.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 757, we get 757.
Append the next digit (6) from the dividend to 757 and continue with: 7576 / 770

Moving on to step 4:
7576 divided by 770 is 9 with a remainder of 646.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 6930 away from 7576, we end up with 646.
Fetch the next digit (7) from the dividend, attach it to 646 and continue: 6467 / 770

Step 5:
The number 770 fits into 6467 8 times, leaving a remainder of 307.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we subtract 6160 from 6467, we get 307.
Fetch the next digit (9) from the dividend, attach it to 307 and continue: 3079 / 770

Advancing to step 6:
770 goes into 3079 3 times with a remainder of 769.
Write down 3 as next digit of the result. 
Result so far: 983.0
Deduct 2310 from 3079 and we're left with 769.
Grab the next digit (1) from the dividend, add it to 769, then carry on: 7691 / 770

Advancing to step 7:
The number 770 fits into 7691 9 times, leaving a remainder of 761.
Use 9 as the next digit of our solution. 
Result so far: 9839.0
Subtracting 6930 from 7691 leaves us with 761.
Include the next digit (5) from the dividend after 761, then repeat: 7615 / 770

Moving on to step 8:
If we divide 7615 by 770, we get 9 and a remainder of 685.
Use 9 as the next digit of our solution. 
Result so far: 98399.0
Deduct 6930 from 7615 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 9:
The number 770 fits into 6850 8 times, leaving a remainder of 690.
The next digit of our result is 8. 
Result so far: 98399.8
The remainder is 690 after subtracting 6160 from 6850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 10:
If we divide 6900 by 770, we get 8 and a remainder of 740.
Put 8 as the next digit of the answer. 
Result so far: 98399.88
Subtracting 6160 from 6900 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The quotient of the division is 98399.88, and the remainder is 0.74.
