525368 ÷ 78 
The aim is to understand the frequency of 78 in 525368.

Advancing to step 1:
78 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 78

Advancing to step 2:
52 divided by 78 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 78

Let's proceed to step 3:
The number 78 fits into 525 6 times, leaving a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 468 from 525, we get 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 78

Moving on to step 4:
78 can be fit into 573 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 546 from 573 and we're left with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 78

Let's proceed to step 5:
If we divide 276 by 78, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
The remainder is 42 after subtracting 234 from 276.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 78

Let's proceed to step 6:
The number 78 fits into 428 5 times, leaving a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 6735.0
If we subtract 390 from 428, we 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.

Advancing to step 7:
78 goes into 380 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 6735.4
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
78 goes into 680 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 6735.48
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 9:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 6735.487
Deduct 546 from 560 and we're left with 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 10:
78 goes into 140 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 6735.4871
Subtracting 78 from 140 leaves us 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.

Going ahead to step 11:
If we divide 620 by 78, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 6735.48717
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.

Step 12:
740 divided by 78 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 6735.487179
Deduct 702 from 740 and we're left 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.

Advancing to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 6735.4871794
Subtracting 312 from 380 leaves us 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.

Going ahead to step 14:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6735.48717948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 6735.48717948 with a remainder of 5.6e-08.
