64305699 ÷ 412 
The aim is to understand the frequency of 412 in 64305699.

Step 1:
If we divide 6 by 412, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 412

On to step 2:
64 divided by 412 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 412

Going ahead to step 3:
412 can be fit into 643 1 times, resulting in a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 412 from 643 and we're left with 231.
Bring next digit (0) of the dividend behind the 231 and repeat the process: 2310 / 412

Going ahead to step 4:
412 goes into 2310 5 times with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2060 from 2310 to get 250.
Fetch the next digit (5) from the dividend, attach it to 250 and continue: 2505 / 412

Moving on to step 5:
If we divide 2505 by 412, we get 6 and a remainder of 33.
The next digit of our result is 6. 
Result so far: 156.0
Deduct 2472 from 2505 and we're left with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 412

Moving on to step 6:
412 goes into 336 0 times with a remainder of 336.
Write down 0 as next digit of the result. 
Result so far: 1560.0
If we subtract 0 from 336, we get 336.
Bring next digit (9) of the dividend behind the 336 and repeat the process: 3369 / 412

Moving on to step 7:
When dividing 3369 by 412, we get 8 with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 15608.0
The remainder is 73 after subtracting 3296 from 3369.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 412

Advancing to step 8:
If we divide 739 by 412, we get 1 and a remainder of 327.
The next digit of our result is 1. 
Result so far: 156081.0
Subtracting 412 from 739 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 9:
If we divide 3270 by 412, we get 7 and a remainder of 386.
Write down 7 as next digit of the result. 
Result so far: 156081.7
Subtract 2884 from 3270 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
412 goes into 3860 9 times with a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 156081.79
Subtract 3708 from 3860 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 11:
When dividing 1520 by 412, we get 3 with a remainder of 284.
The number 3 becomes the next digit in our result. 
Result so far: 156081.793
Deduct 1236 from 1520 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 12:
If we divide 2840 by 412, we get 6 and a remainder of 368.
The next digit of our result is 6. 
Result so far: 156081.7936
If we subtract 2472 from 2840, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 13:
3680 divided by 412 is 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 156081.79368
The remainder is 384 after subtracting 3296 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 14:
When dividing 3840 by 412, we get 9 with a remainder of 132.
The next digit of our result is 9. 
Result so far: 156081.793689
Subtracting 3708 from 3840 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 15:
412 can be fit into 1320 3 times, resulting in a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 156081.7936893
If we subtract 1236 from 1320, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
When dividing 840 by 412, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 156081.79368932
The remainder is 16 after subtracting 824 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 156081.79368932 with a remainder of 1.6e-08.
