67176616 ÷ 786 
The aim is to understand the frequency of 786 in 67176616.

Advancing to step 1:
When dividing 6 by 786, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 786

Going ahead to step 2:
When dividing 67 by 786, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 786

Step 3:
When dividing 671 by 786, we get 0 with a remainder of 671.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 671, we end up with 671.
Take the next digit (7) from the dividend and append it to 671, then repeat: 6717 / 786

On to step 4:
The number 786 fits into 6717 8 times, leaving a remainder of 429.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 6288 away from 6717, we end up with 429.
Append the next digit (6) from the dividend to 429 and continue with: 4296 / 786

Step 5:
4296 divided by 786 is 5 with a remainder of 366.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 3930 from 4296, we get 366.
Fetch the next digit (6) from the dividend, attach it to 366 and continue: 3666 / 786

Advancing to step 6:
786 goes into 3666 4 times with a remainder of 522.
Put 4 as the next digit of the answer. 
Result so far: 854.0
The remainder is 522 after subtracting 3144 from 3666.
Grab the next digit (1) from the dividend, add it to 522, then carry on: 5221 / 786

Let's proceed to step 7:
786 goes into 5221 6 times with a remainder of 505.
Use 6 as the next digit of our solution. 
Result so far: 8546.0
The remainder is 505 after subtracting 4716 from 5221.
Fetch the next digit (6) from the dividend, attach it to 505 and continue: 5056 / 786

Step 8:
5056 divided by 786 is 6 with a remainder of 340.
Record the quotient 6 as the next digit in the result. 
Result so far: 85466.0
If we take 4716 away from 5056, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 9:
786 goes into 3400 4 times with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 85466.4
Subtracting 3144 from 3400 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 10:
The number 786 fits into 2560 3 times, leaving a remainder of 202.
Use 3 as the next digit of our solution. 
Result so far: 85466.43
If we subtract 2358 from 2560, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 11:
If we divide 2020 by 786, we get 2 and a remainder of 448.
The next digit of our result is 2. 
Result so far: 85466.432
The remainder is 448 after subtracting 1572 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
786 goes into 4480 5 times with a remainder of 550.
The next digit of our result is 5. 
Result so far: 85466.4325
Subtract 3930 from 4480 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 13:
5500 divided by 786 is 6 with a remainder of 784.
The number 6 becomes the next digit in our result. 
Result so far: 85466.43256
If we take 4716 away from 5500, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 14:
786 goes into 7840 9 times with a remainder of 766.
The next digit of our result is 9. 
Result so far: 85466.432569
Deduct 7074 from 7840 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 15:
786 can be fit into 7660 9 times, resulting in a remainder of 586.
Use 9 as the next digit of our solution. 
Result so far: 85466.4325699
Subtract 7074 from 7660 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

The quotient of the division is 85466.4325699, and the remainder is 5.86e-06.
