We're dividing 392151 by 78 
The aim is to understand the frequency of 78 in 392151.

Moving on to step 1:
78 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 78

Advancing to step 2:
78 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 78

Step 3:
When dividing 392 by 78, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 390 from 392 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 78

Moving on to step 4:
78 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 78

Advancing to step 5:
The number 78 fits into 215 2 times, leaving a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 502.0
The remainder is 59 after subtracting 156 from 215.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 78

Advancing to step 6:
The number 78 fits into 591 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 5027.0
Subtracting 546 from 591 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
If we divide 450 by 78, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 5027.5
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 5027.57
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
540 divided by 78 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 5027.576
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 5027.5769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 78 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5027.57692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
78 goes into 240 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 5027.576923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 78 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5027.576923
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
600 divided by 78 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5027.57692307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 5027.57692307, and the remainder is 5.4e-08.
