We look at the division of 860900 by 78 
The aim is to understand the frequency of 78 in 860900.

Going ahead to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 78

Step 2:
If we divide 86 by 78, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 78 from 86 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 78

Let's proceed to step 3:
80 divided by 78 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 78 from 80 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 78

Let's proceed to step 4:
78 can be fit into 29 0 times, resulting in a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 29, we get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 78

Moving on to step 5:
When dividing 290 by 78, we get 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
Subtracting 234 from 290 leaves us with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 78

Step 6:
If we divide 560 by 78, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11037.0
If we subtract 546 from 560, 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.

On to step 7:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 11037.1
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 11037.17
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 11037.179
The remainder is 38 after subtracting 702 from 740.
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 10:
When dividing 380 by 78, we get 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 11037.1794
Subtract 312 from 380 to 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.

On to step 11:
78 can be fit into 680 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 11037.17948
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.

Going ahead to step 12:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 11037.179487
Subtracting 546 from 560 leaves us 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 13:
If we divide 140 by 78, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 11037.1794871
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.

Going ahead to step 14:
If we divide 620 by 78, we get 7 and a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 11037.17948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 11037.17948717 with a balance of 7.4e-08.
