77308244 ÷ 770 
The aim is to understand the frequency of 770 in 77308244.

Moving on to step 1:
If we divide 7 by 770, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 770

Moving on to step 2:
770 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 770

On to step 3:
If we divide 773 by 770, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 770 from 773 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 770

Moving on to step 4:
When dividing 30 by 770, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 770

Step 5:
770 goes into 308 0 times with a remainder of 308.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 308 after subtracting 0 from 308.
Grab the next digit (2) from the dividend, add it to 308, then carry on: 3082 / 770

On to step 6:
770 goes into 3082 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1004.0
Subtracting 3080 from 3082 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 770

Step 7:
The number 770 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 10040.0
Subtract 0 from 24 to get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 770

Step 8:
244 divided by 770 is 0 with a remainder of 244.
Use 0 as the next digit of our solution. 
Result so far: 100400.0
Deduct 0 from 244 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 9:
770 can be fit into 2440 3 times, resulting in a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 100400.3
If we take 2310 away from 2440, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
The number 770 fits into 1300 1 times, leaving a remainder of 530.
Put 1 as the next digit of the answer. 
Result so far: 100400.31
The remainder is 530 after subtracting 770 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 11:
When dividing 5300 by 770, we get 6 with a remainder of 680.
Write down 6 as next digit of the result. 
Result so far: 100400.316
Subtracting 4620 from 5300 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 12:
The number 770 fits into 6800 8 times, leaving a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 100400.3168
If we take 6160 away from 6800, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
770 can be fit into 6400 8 times, resulting in a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 100400.31688
Deduct 6160 from 6400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 100400.31688 and a remainder of 0.00024.
