Let's divide 187948 by 78
The aim is to understand the frequency of 78 in 187948.

Moving on to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 78

Advancing to step 2:
The number 78 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 78

Advancing to step 3:
The number 78 fits into 187 2 times, leaving a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 31 after subtracting 156 from 187.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 78

On to step 4:
319 divided by 78 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 312 away from 319, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 78

On to step 5:
78 can be fit into 74 0 times, resulting in a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we subtract 0 from 74, we get 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 78

Moving on to step 6:
78 goes into 748 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 2409.0
Subtract 702 from 748 to get 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 7:
460 divided by 78 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2409.5
Deduct 390 from 460 and we're left 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 8:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 2409.58
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.

Advancing to step 9:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 2409.589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
78 goes into 580 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 2409.5897
Subtracting 546 from 580 leaves us 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.

On to step 11:
When dividing 340 by 78, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 2409.58974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 2409.589743
Subtract 234 from 280 to get 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:
460 divided by 78 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 2409.5897435
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.

Going ahead to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 2409.58974358
Subtracting 624 from 700 leaves us 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.

After the division, we end up with 2409.58974358 and a remainder of 7.6e-08.
