We're dividing 18802830 by 412 
The aim is to understand the frequency of 412 in 18802830.

Going ahead to step 1:
The number 412 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 412

Moving on to step 2:
412 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 412

On to step 3:
412 goes into 188 0 times with a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 188 and we're left with 188.
Bring next digit (0) of the dividend behind the 188 and repeat the process: 1880 / 412

Going ahead to step 4:
The number 412 fits into 1880 4 times, leaving a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1648 from 1880 leaves us with 232.
Append the next digit (2) from the dividend to 232 and continue with: 2322 / 412

Moving on to step 5:
412 can be fit into 2322 5 times, resulting in a remainder of 262.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 2060 from 2322 and we're left with 262.
Include the next digit (8) from the dividend after 262, then repeat: 2628 / 412

On to step 6:
If we divide 2628 by 412, we get 6 and a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
Subtract 2472 from 2628 to get 156.
Include the next digit (3) from the dividend after 156, then repeat: 1563 / 412

Let's proceed to step 7:
The number 412 fits into 1563 3 times, leaving a remainder of 327.
Write down 3 as next digit of the result. 
Result so far: 4563.0
If we subtract 1236 from 1563, we get 327.
Fetch the next digit (0) from the dividend, attach it to 327 and continue: 3270 / 412

Step 8:
When dividing 3270 by 412, we get 7 with a remainder of 386.
Record the quotient 7 as the next digit in the result. 
Result so far: 45637.0
Subtracting 2884 from 3270 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
412 goes into 3860 9 times with a remainder of 152.
Record the quotient 9 as the next digit in the result. 
Result so far: 45637.9
The remainder is 152 after subtracting 3708 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
If we divide 1520 by 412, we get 3 and a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 45637.93
If we take 1236 away from 1520, we end up 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.

On to step 11:
2840 divided by 412 is 6 with a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 45637.936
Subtract 2472 from 2840 to 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.

Moving on to step 12:
When dividing 3680 by 412, we get 8 with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 45637.9368
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.

Step 13:
The number 412 fits into 3840 9 times, leaving a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 45637.93689
Subtract 3708 from 3840 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
412 can be fit into 1320 3 times, resulting in a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 45637.936893
Subtracting 1236 from 1320 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
The number 412 fits into 840 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 45637.9368932
Subtracting 824 from 840 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
If we divide 160 by 412, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 45637.9368932
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 45637.9368932, with a leftover of 1.6e-07.
