844591 divided by 78 
The aim is to understand the frequency of 78 in 844591.

Let's proceed to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 78

On to step 2:
When dividing 84 by 78, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 78 away from 84, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 78

Moving on to step 3:
If we divide 64 by 78, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 78

Let's proceed to step 4:
78 goes into 645 8 times with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 624 from 645 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 78

Let's proceed to step 5:
78 can be fit into 219 2 times, resulting in a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 1082.0
Subtracting 156 from 219 leaves us with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 78

Moving on to step 6:
631 divided by 78 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 10828.0
Subtracting 624 from 631 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
78 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 10828.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 10828.08
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 10828.089
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
580 divided by 78 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 10828.0897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
78 goes into 340 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 10828.08974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 78, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 10828.089743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 10828.0897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
When dividing 700 by 78, we get 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 10828.08974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 10828.08974358 with a remaining 7.6e-08.
