We divide 147663 by 78
The aim is to understand the frequency of 78 in 147663.

Going ahead to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 78

Advancing to step 2:
If we divide 14 by 78, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 78

Moving on to step 3:
78 goes into 147 1 times with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 78 from 147, we get 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 78

Advancing to step 4:
78 can be fit into 696 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 624 from 696, we get 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 78

Going ahead to step 5:
726 divided by 78 is 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 189.0
Deduct 702 from 726 and we're left with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 78

On to step 6:
If we divide 243 by 78, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 1893.0
Subtracting 234 from 243 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 78 fits into 90 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1893.1
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 78, we get 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1893.11
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 1893.11 with a remainder of 0.042.
