We look at the division of 75896644 by 781 
The aim is to understand the frequency of 781 in 75896644.

Advancing to step 1:
When dividing 7 by 781, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 781

Let's proceed to step 2:
When dividing 75 by 781, we get 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 781

On to step 3:
The number 781 fits into 758 0 times, leaving a remainder of 758.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 758 leaves us with 758.
Include the next digit (9) from the dividend after 758, then repeat: 7589 / 781

Moving on to step 4:
The number 781 fits into 7589 9 times, leaving a remainder of 560.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 560 after subtracting 7029 from 7589.
Bring next digit (6) of the dividend behind the 560 and repeat the process: 5606 / 781

Step 5:
If we divide 5606 by 781, we get 7 and a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 5467 from 5606 leaves us with 139.
Take the next digit (6) from the dividend and append it to 139, then repeat: 1396 / 781

Going ahead to step 6:
781 can be fit into 1396 1 times, resulting in a remainder of 615.
Put 1 as the next digit of the answer. 
Result so far: 971.0
If we take 781 away from 1396, we end up with 615.
Bring next digit (4) of the dividend behind the 615 and repeat the process: 6154 / 781

Step 7:
781 goes into 6154 7 times with a remainder of 687.
The next digit of our result is 7. 
Result so far: 9717.0
If we take 5467 away from 6154, we end up with 687.
Include the next digit (4) from the dividend after 687, then repeat: 6874 / 781

Let's proceed to step 8:
781 can be fit into 6874 8 times, resulting in a remainder of 626.
The next digit of our result is 8. 
Result so far: 97178.0
If we take 6248 away from 6874, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 9:
781 can be fit into 6260 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 97178.8
Subtract 6248 from 6260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
781 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 97178.8
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
When dividing 1200 by 781, we get 1 with a remainder of 419.
Use 1 as the next digit of our solution. 
Result so far: 97178.801
Subtracting 781 from 1200 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 12:
When dividing 4190 by 781, we get 5 with a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 97178.8015
Subtract 3905 from 4190 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 13:
When dividing 2850 by 781, we get 3 with a remainder of 507.
The number 3 becomes the next digit in our result. 
Result so far: 97178.80153
If we subtract 2343 from 2850, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 14:
5070 divided by 781 is 6 with a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 97178.801536
Subtracting 4686 from 5070 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 15:
When dividing 3840 by 781, we get 4 with a remainder of 716.
The next digit of our result is 4. 
Result so far: 97178.8015364
The remainder is 716 after subtracting 3124 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 16:
781 goes into 7160 9 times with a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 97178.80153649
If we take 7029 away from 7160, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

In conclusion, the division gives 97178.80153649 with a balance of 1.31e-07.
