We look at the division of 780678 by 61 
The aim is to understand the frequency of 61 in 780678.

Moving on to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 61

Let's proceed to step 2:
When dividing 78 by 61, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 61 from 78 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 61

Let's proceed to step 3:
The number 61 fits into 170 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 122 from 170, we get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 61

Step 4:
If we divide 486 by 61, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 427 from 486 and we're left with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 61

Advancing to step 5:
61 can be fit into 597 9 times, resulting in a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 1279.0
The remainder is 48 after subtracting 549 from 597.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 61

Advancing to step 6:
61 goes into 488 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 12798.0
If we subtract 488 from 488, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 61 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12798.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
61 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12798.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 12798.0 with a balance of 0.0.
