We divide 91865 by 78
The aim is to understand the frequency of 78 in 91865.

On to step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 78

Advancing to step 2:
When dividing 91 by 78, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 78 from 91 leaves us with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 78

Going ahead to step 3:
78 goes into 138 1 times with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 78 from 138 and we're left with 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 78

Moving on to step 4:
The number 78 fits into 606 7 times, leaving a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 60 after subtracting 546 from 606.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 78

Advancing to step 5:
605 divided by 78 is 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 1177.0
Subtract 546 from 605 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 6:
590 divided by 78 is 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 1177.7
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1177.75
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1177.756
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1177.7564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 78 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1177.75641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1177.75641
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 78, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1177.7564102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
When dividing 440 by 78, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1177.75641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 1177.75641025 with a balance of 5e-08.
