We divide 152525 by 78
The aim is to understand the frequency of 78 in 152525.

Advancing to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 78

On to step 2:
78 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 78

Going ahead to step 3:
If we divide 152 by 78, we get 1 and a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 152 to get 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 78

Advancing to step 4:
When dividing 745 by 78, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 43 after subtracting 702 from 745.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 78

Advancing to step 5:
If we divide 432 by 78, we get 5 and a remainder of 42.
The next digit of our result is 5. 
Result so far: 195.0
Deduct 390 from 432 and we're left with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 78

Step 6:
When dividing 425 by 78, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1955.0
If we take 390 away from 425, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
78 goes into 350 4 times with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 1955.4
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
When dividing 380 by 78, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 1955.44
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 1955.44, and the remainder is 0.068.
