We're dividing 61307681 by 412 
The aim is to understand the frequency of 412 in 61307681.

Step 1:
412 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 412

Moving on to step 2:
If we divide 61 by 412, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 412

Going ahead to step 3:
412 goes into 613 1 times with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 412 from 613 to get 201.
Take the next digit (0) from the dividend and append it to 201, then repeat: 2010 / 412

On to step 4:
If we divide 2010 by 412, we get 4 and a remainder of 362.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 1648 from 2010, we get 362.
Fetch the next digit (7) from the dividend, attach it to 362 and continue: 3627 / 412

Advancing to step 5:
The number 412 fits into 3627 8 times, leaving a remainder of 331.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Deduct 3296 from 3627 and we're left with 331.
Bring next digit (6) of the dividend behind the 331 and repeat the process: 3316 / 412

Step 6:
The number 412 fits into 3316 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1488.0
The remainder is 20 after subtracting 3296 from 3316.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 412

Let's proceed to step 7:
412 goes into 208 0 times with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 14880.0
Subtract 0 from 208 to get 208.
Include the next digit (1) from the dividend after 208, then repeat: 2081 / 412

Going ahead to step 8:
412 goes into 2081 5 times with a remainder of 21.
The next digit of our result is 5. 
Result so far: 148805.0
If we take 2060 away from 2081, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
412 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 148805.0
The remainder is 210 after subtracting 0 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
When dividing 2100 by 412, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 148805.05
Deduct 2060 from 2100 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
412 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 148805.05
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
When dividing 4000 by 412, we get 9 with a remainder of 292.
Use 9 as the next digit of our solution. 
Result so far: 148805.0509
Deduct 3708 from 4000 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 13:
2920 divided by 412 is 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 148805.05097
Subtracting 2884 from 2920 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
When dividing 360 by 412, we get 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 148805.05097
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 15:
If we divide 3600 by 412, we get 8 and a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 148805.0509708
Subtracting 3296 from 3600 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 16:
The number 412 fits into 3040 7 times, leaving a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 148805.05097087
Subtract 2884 from 3040 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final result is 148805.05097087 with a remainder of 1.56e-07.
