We divide 72550 by 78
The aim is to understand the frequency of 78 in 72550.

Going ahead to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 78

Going ahead to step 2:
72 divided by 78 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 78

Let's proceed to step 3:
The number 78 fits into 725 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 702 from 725 leaves us with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 78

Moving on to step 4:
The number 78 fits into 235 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtract 234 from 235 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 78

On to step 5:
78 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 930.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
When dividing 100 by 78, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 930.1
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 930.12
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 930.128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 78 fits into 160 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 930.1282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 930.1282
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 78 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 930.128205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 930.1282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
If we divide 220 by 78, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 930.12820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 930.12820512 with a balance of 6.4e-08.
