860537 ÷ 78 
The aim is to understand the frequency of 78 in 860537.

Step 1:
8 divided by 78 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 78

Advancing to step 2:
If we divide 86 by 78, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 86, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 78

Let's proceed to step 3:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 78 from 80 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 78

Advancing to step 4:
The number 78 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 25 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 78

Moving on to step 5:
When dividing 253 by 78, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 1103.0
Subtracting 234 from 253 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 78

Advancing to step 6:
When dividing 197 by 78, we get 2 with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 11032.0
Subtracting 156 from 197 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
78 can be fit into 410 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 11032.5
If we take 390 away from 410, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 11032.52
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 78, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 11032.525
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 78, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 11032.5256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 78, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 11032.52564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
78 goes into 80 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11032.525641
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11032.525641
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
78 goes into 200 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 11032.52564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 11032.52564102 with a remainder of 4.4e-08.
