787960 divided by 61 
The aim is to understand the frequency of 61 in 787960.

Step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 61

Moving on to step 2:
61 can be fit into 78 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 61 from 78 leaves us with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 61

On to step 3:
When dividing 177 by 61, we get 2 with a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 122 from 177 to get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 61

On to step 4:
The number 61 fits into 559 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we subtract 549 from 559, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 61

Step 5:
106 divided by 61 is 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1291.0
If we take 61 away from 106, we end up with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 61

Let's proceed to step 6:
When dividing 450 by 61, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 12917.0
Subtracting 427 from 450 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 61 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 12917.3
Subtract 183 from 230 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 8:
61 can be fit into 470 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 12917.37
Deduct 427 from 470 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
The number 61 fits into 430 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12917.377
If we take 427 away from 430, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 12917.377 with a remaining 0.0003.
