We're dividing 2218407 by 546 
The aim is to understand the frequency of 546 in 2218407.

Step 1:
The number 546 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 546

On to step 2:
22 divided by 546 is 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 546

Let's proceed to step 3:
221 divided by 546 is 0 with a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 221, we get 221.
Grab the next digit (8) from the dividend, add it to 221, then carry on: 2218 / 546

On to step 4:
When dividing 2218 by 546, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2184 from 2218, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 546

On to step 5:
If we divide 344 by 546, we get 0 and a remainder of 344.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 344 leaves us with 344.
Include the next digit (0) from the dividend after 344, then repeat: 3440 / 546

Going ahead to step 6:
The number 546 fits into 3440 6 times, leaving a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 406.0
Subtract 3276 from 3440 to get 164.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 546

Let's proceed to step 7:
546 can be fit into 1647 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 4063.0
The remainder is 9 after subtracting 1638 from 1647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
If we divide 90 by 546, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 4063.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
900 divided by 546 is 1 with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 4063.01
If we take 546 away from 900, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 10:
3540 divided by 546 is 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 4063.016
If we subtract 3276 from 3540, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
If we divide 2640 by 546, we get 4 and a remainder of 456.
The next digit of our result is 4. 
Result so far: 4063.0164
Subtracting 2184 from 2640 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 12:
The number 546 fits into 4560 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 4063.01648
The remainder is 192 after subtracting 4368 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 13:
If we divide 1920 by 546, we get 3 and a remainder of 282.
Use 3 as the next digit of our solution. 
Result so far: 4063.016483
The remainder is 282 after subtracting 1638 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 14:
If we divide 2820 by 546, we get 5 and a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 4063.0164835
Subtract 2730 from 2820 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
900 divided by 546 is 1 with a remainder of 354.
Record the quotient 1 as the next digit in the result. 
Result so far: 4063.01648351
Deduct 546 from 900 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final result is 4063.01648351 with a remainder of 3.54e-07.
