372779 divided by 78 
The aim is to understand the frequency of 78 in 372779.

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
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 78

Let's proceed to step 2:
78 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 78

On to step 3:
372 divided by 78 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 312 from 372, we get 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 78

On to step 4:
When dividing 607 by 78, we get 7 with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 61 after subtracting 546 from 607.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 78

On to step 5:
The number 78 fits into 617 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Subtracting 546 from 617 leaves us with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 78

Let's proceed to step 6:
78 can be fit into 719 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 4779.0
Subtract 702 from 719 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 78 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 4779.2
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
When dividing 140 by 78, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 4779.21
If we take 78 away from 140, we end up with 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 9:
If we divide 620 by 78, we get 7 and a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 4779.217
If we subtract 546 from 620, we 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.

Advancing to step 10:
78 goes into 740 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4779.2179
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.

Let's proceed to step 11:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 4779.21794
Deduct 312 from 380 and we're left 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.

Step 12:
78 goes into 680 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 4779.217948
If we take 624 away from 680, we end up 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.

Going ahead to step 13:
When dividing 560 by 78, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4779.2179487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 4779.21794871
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.

In conclusion, the division gives 4779.21794871 with a balance of 6.2e-08.
