We look at the division of 369665 by 78 
The aim is to understand the frequency of 78 in 369665.

Moving on to step 1:
78 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

Let's proceed to step 2:
78 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 78

Let's proceed to step 3:
78 goes into 369 4 times with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 312 from 369 to get 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 78

Going ahead to step 4:
576 divided by 78 is 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 546 from 576 and we're left with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 78

Let's proceed to step 5:
When dividing 306 by 78, we get 3 with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 473.0
Deduct 234 from 306 and we're left with 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 78

Let's proceed to step 6:
725 divided by 78 is 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 4739.0
Deduct 702 from 725 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
The number 78 fits into 230 2 times, leaving a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 4739.2
Subtract 156 from 230 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
When dividing 740 by 78, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4739.29
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 78, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4739.294
If we take 312 away from 380, we end up 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.

Moving on to step 10:
If we divide 680 by 78, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 4739.2948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 78 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4739.29487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 78, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 4739.294871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
78 goes into 620 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 4739.2948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 14:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 4739.29487179
If we take 702 away from 740, we end up 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.

The quotient of the division is 4739.29487179, and the remainder is 3.8e-08.
