56428729 divided by 820 
The aim is to understand the frequency of 820 in 56428729.

Advancing to step 1:
When dividing 5 by 820, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 820

Going ahead to step 2:
If we divide 56 by 820, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 820

Let's proceed to step 3:
564 divided by 820 is 0 with a remainder of 564.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 564, we get 564.
Take the next digit (2) from the dividend and append it to 564, then repeat: 5642 / 820

Advancing to step 4:
820 goes into 5642 6 times with a remainder of 722.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4920 away from 5642, we end up with 722.
Take the next digit (8) from the dividend and append it to 722, then repeat: 7228 / 820

Advancing to step 5:
When dividing 7228 by 820, we get 8 with a remainder of 668.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 6560 away from 7228, we end up with 668.
Bring next digit (7) of the dividend behind the 668 and repeat the process: 6687 / 820

Let's proceed to step 6:
The number 820 fits into 6687 8 times, leaving a remainder of 127.
The next digit of our result is 8. 
Result so far: 688.0
If we subtract 6560 from 6687, we get 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 820

Advancing to step 7:
If we divide 1272 by 820, we get 1 and a remainder of 452.
Use 1 as the next digit of our solution. 
Result so far: 6881.0
Deduct 820 from 1272 and we're left with 452.
Bring next digit (9) of the dividend behind the 452 and repeat the process: 4529 / 820

Let's proceed to step 8:
820 can be fit into 4529 5 times, resulting in a remainder of 429.
The number 5 becomes the next digit in our result. 
Result so far: 68815.0
Subtracting 4100 from 4529 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
When dividing 4290 by 820, we get 5 with a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 68815.5
Subtracting 4100 from 4290 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
1900 divided by 820 is 2 with a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 68815.52
If we take 1640 away from 1900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
820 goes into 2600 3 times with a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 68815.523
If we take 2460 away from 2600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
When dividing 1400 by 820, we get 1 with a remainder of 580.
Write down 1 as next digit of the result. 
Result so far: 68815.5231
If we take 820 away from 1400, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 13:
The number 820 fits into 5800 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 68815.52317
Subtracting 5740 from 5800 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 820, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 68815.52317
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
820 can be fit into 6000 7 times, resulting in a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 68815.5231707
The remainder is 260 after subtracting 5740 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
820 can be fit into 2600 3 times, resulting in a remainder of 140.
The next digit of our result is 3. 
Result so far: 68815.52317073
If we take 2460 away from 2600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 68815.52317073 and a remainder of 1.4e-07.
