56717221 ÷ 546 
The aim is to understand the frequency of 546 in 56717221.

Moving on to step 1:
If we divide 5 by 546, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 546

On to step 2:
546 can be fit into 56 0 times, resulting in a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 546

Step 3:
The number 546 fits into 567 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 546 from 567 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 546

Moving on to step 4:
When dividing 211 by 546, we get 0 with a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 211 after subtracting 0 from 211.
Grab the next digit (7) from the dividend, add it to 211, then carry on: 2117 / 546

Let's proceed to step 5:
If we divide 2117 by 546, we get 3 and a remainder of 479.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 1638 away from 2117, we end up with 479.
Fetch the next digit (2) from the dividend, attach it to 479 and continue: 4792 / 546

Advancing to step 6:
4792 divided by 546 is 8 with a remainder of 424.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
Subtract 4368 from 4792 to get 424.
Bring next digit (2) of the dividend behind the 424 and repeat the process: 4242 / 546

Going ahead to step 7:
The number 546 fits into 4242 7 times, leaving a remainder of 420.
The next digit of our result is 7. 
Result so far: 10387.0
If we take 3822 away from 4242, we end up with 420.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 546

Going ahead to step 8:
546 can be fit into 4201 7 times, resulting in a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 103877.0
If we subtract 3822 from 4201, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 9:
3790 divided by 546 is 6 with a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 103877.6
Deduct 3276 from 3790 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 10:
The number 546 fits into 5140 9 times, leaving a remainder of 226.
The next digit of our result is 9. 
Result so far: 103877.69
Deduct 4914 from 5140 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 11:
The number 546 fits into 2260 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 103877.694
Subtracting 2184 from 2260 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
If we divide 760 by 546, we get 1 and a remainder of 214.
The next digit of our result is 1. 
Result so far: 103877.6941
If we subtract 546 from 760, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
The number 546 fits into 2140 3 times, leaving a remainder of 502.
Put 3 as the next digit of the answer. 
Result so far: 103877.69413
Subtract 1638 from 2140 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 14:
546 can be fit into 5020 9 times, resulting in a remainder of 106.
The number 9 becomes the next digit in our result. 
Result so far: 103877.694139
Deduct 4914 from 5020 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 15:
1060 divided by 546 is 1 with a remainder of 514.
Put 1 as the next digit of the answer. 
Result so far: 103877.6941391
Deduct 546 from 1060 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 16:
546 can be fit into 5140 9 times, resulting in a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 103877.69413919
Subtracting 4914 from 5140 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 103877.69413919, with a leftover of 2.26e-07.
