Let's divide 780510 by 11
The aim is to understand the frequency of 11 in 780510.

Step 1:
11 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 11

Let's proceed to step 2:
If we divide 78 by 11, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 77 from 78 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 11

Moving on to step 3:
When dividing 10 by 11, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 11

Moving on to step 4:
If we divide 105 by 11, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 709.0
If we take 99 away from 105, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 11

On to step 5:
11 can be fit into 61 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 7095.0
The remainder is 6 after subtracting 55 from 61.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 11

Step 6:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 70955.0
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 70955.4
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
11 goes into 60 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 70955.45
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 70955.454
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 70955.4545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 70955.45454
Subtracting 44 from 50 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 70955.454545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
If we divide 50 by 11, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 70955.4545454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 70955.45454545
Deduct 55 from 60 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 70955.45454545, and the remainder is 5e-09.
