We're dividing 91517841 by 779 
The aim is to understand the frequency of 779 in 91517841.

Advancing to step 1:
779 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 779

Let's proceed to step 2:
When dividing 91 by 779, we get 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 779

Let's proceed to step 3:
If we divide 915 by 779, we get 1 and a remainder of 136.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 779 from 915 leaves us with 136.
Take the next digit (1) from the dividend and append it to 136, then repeat: 1361 / 779

On to step 4:
779 can be fit into 1361 1 times, resulting in a remainder of 582.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 779 from 1361 leaves us with 582.
Take the next digit (7) from the dividend and append it to 582, then repeat: 5827 / 779

On to step 5:
When dividing 5827 by 779, we get 7 with a remainder of 374.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 5453 from 5827 to get 374.
Append the next digit (8) from the dividend to 374 and continue with: 3748 / 779

Let's proceed to step 6:
3748 divided by 779 is 4 with a remainder of 632.
Use 4 as the next digit of our solution. 
Result so far: 1174.0
If we take 3116 away from 3748, we end up with 632.
Append the next digit (4) from the dividend to 632 and continue with: 6324 / 779

Let's proceed to step 7:
When dividing 6324 by 779, we get 8 with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 11748.0
Deduct 6232 from 6324 and we're left with 92.
Fetch the next digit (1) from the dividend, attach it to 92 and continue: 921 / 779

Step 8:
779 goes into 921 1 times with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 117481.0
If we subtract 779 from 921, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
The number 779 fits into 1420 1 times, leaving a remainder of 641.
Record the quotient 1 as the next digit in the result. 
Result so far: 117481.1
The remainder is 641 after subtracting 779 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Advancing to step 10:
If we divide 6410 by 779, we get 8 and a remainder of 178.
Use 8 as the next digit of our solution. 
Result so far: 117481.18
If we take 6232 away from 6410, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 11:
1780 divided by 779 is 2 with a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 117481.182
If we subtract 1558 from 1780, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 12:
779 can be fit into 2220 2 times, resulting in a remainder of 662.
Put 2 as the next digit of the answer. 
Result so far: 117481.1822
Deduct 1558 from 2220 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

The quotient of the division is 117481.1822, and the remainder is 0.00662.
