68397546 ÷ 781 
The aim is to understand the frequency of 781 in 68397546.

Step 1:
If we divide 6 by 781, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 781

Moving on to step 2:
If we divide 68 by 781, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 781

On to step 3:
781 goes into 683 0 times with a remainder of 683.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 683 leaves us with 683.
Include the next digit (9) from the dividend after 683, then repeat: 6839 / 781

Moving on to step 4:
6839 divided by 781 is 8 with a remainder of 591.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 591 after subtracting 6248 from 6839.
Include the next digit (7) from the dividend after 591, then repeat: 5917 / 781

Advancing to step 5:
781 goes into 5917 7 times with a remainder of 450.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 5467 away from 5917, we end up with 450.
Fetch the next digit (5) from the dividend, attach it to 450 and continue: 4505 / 781

Moving on to step 6:
The number 781 fits into 4505 5 times, leaving a remainder of 600.
Use 5 as the next digit of our solution. 
Result so far: 875.0
The remainder is 600 after subtracting 3905 from 4505.
Include the next digit (4) from the dividend after 600, then repeat: 6004 / 781

Let's proceed to step 7:
The number 781 fits into 6004 7 times, leaving a remainder of 537.
Use 7 as the next digit of our solution. 
Result so far: 8757.0
Deduct 5467 from 6004 and we're left with 537.
Take the next digit (6) from the dividend and append it to 537, then repeat: 5376 / 781

Step 8:
The number 781 fits into 5376 6 times, leaving a remainder of 690.
The next digit of our result is 6. 
Result so far: 87576.0
Deduct 4686 from 5376 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 9:
The number 781 fits into 6900 8 times, leaving a remainder of 652.
The next digit of our result is 8. 
Result so far: 87576.8
Subtract 6248 from 6900 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 10:
When dividing 6520 by 781, we get 8 with a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 87576.88
Subtract 6248 from 6520 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 87576.88 with a balance of 0.272.
