80910920 ÷ 779 
The aim is to understand the frequency of 779 in 80910920.

Moving on to step 1:
The number 779 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 779

Moving on to step 2:
779 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 779

Let's proceed to step 3:
When dividing 809 by 779, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 30 after subtracting 779 from 809.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 779

Let's proceed to step 4:
779 can be fit into 301 0 times, resulting in a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 301, we end up with 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 779

Moving on to step 5:
779 goes into 3010 3 times with a remainder of 673.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 2337 away from 3010, we end up with 673.
Append the next digit (9) from the dividend to 673 and continue with: 6739 / 779

Let's proceed to step 6:
The number 779 fits into 6739 8 times, leaving a remainder of 507.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
If we subtract 6232 from 6739, we get 507.
Fetch the next digit (2) from the dividend, attach it to 507 and continue: 5072 / 779

Going ahead to step 7:
779 goes into 5072 6 times with a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 10386.0
The remainder is 398 after subtracting 4674 from 5072.
Grab the next digit (0) from the dividend, add it to 398, then carry on: 3980 / 779

Going ahead to step 8:
779 can be fit into 3980 5 times, resulting in a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 103865.0
If we take 3895 away from 3980, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
779 can be fit into 850 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 103865.1
Deduct 779 from 850 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
If we divide 710 by 779, we get 0 and a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 103865.1
If we take 0 away from 710, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 11:
The number 779 fits into 7100 9 times, leaving a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 103865.109
Subtract 7011 from 7100 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 12:
The number 779 fits into 890 1 times, leaving a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 103865.1091
If we take 779 away from 890, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 13:
If we divide 1110 by 779, we get 1 and a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 103865.10911
Subtracting 779 from 1110 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final result is 103865.10911 with a remainder of 0.000331.
