56391821 ÷ 501 
The aim is to understand the frequency of 501 in 56391821.

On to step 1:
5 divided by 501 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 501

Advancing to step 2:
If we divide 56 by 501, we get 0 and 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.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 501

Advancing to step 3:
501 can be fit into 563 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 501 away from 563, we end up with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 501

Going ahead to step 4:
The number 501 fits into 629 1 times, leaving a remainder of 128.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 501 from 629, we get 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 501

Let's proceed to step 5:
501 can be fit into 1281 2 times, resulting in a remainder of 279.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 279 after subtracting 1002 from 1281.
Take the next digit (8) from the dividend and append it to 279, then repeat: 2798 / 501

Let's proceed to step 6:
If we divide 2798 by 501, we get 5 and a remainder of 293.
The next digit of our result is 5. 
Result so far: 1125.0
If we take 2505 away from 2798, we end up with 293.
Bring next digit (2) of the dividend behind the 293 and repeat the process: 2932 / 501

Going ahead to step 7:
2932 divided by 501 is 5 with a remainder of 427.
Use 5 as the next digit of our solution. 
Result so far: 11255.0
If we subtract 2505 from 2932, we get 427.
Bring next digit (1) of the dividend behind the 427 and repeat the process: 4271 / 501

Advancing to step 8:
501 goes into 4271 8 times with a remainder of 263.
Write down 8 as next digit of the result. 
Result so far: 112558.0
The remainder is 263 after subtracting 4008 from 4271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
The number 501 fits into 2630 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 112558.5
If we take 2505 away from 2630, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
The number 501 fits into 1250 2 times, leaving a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 112558.52
Subtract 1002 from 1250 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 11:
501 goes into 2480 4 times with a remainder of 476.
Put 4 as the next digit of the answer. 
Result so far: 112558.524
Subtracting 2004 from 2480 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 12:
The number 501 fits into 4760 9 times, leaving a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 112558.5249
The remainder is 251 after subtracting 4509 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 13:
When dividing 2510 by 501, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 112558.52495
Deduct 2505 from 2510 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
501 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 112558.52495
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
The number 501 fits into 500 0 times, leaving a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 112558.52495
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 112558.52495 and a remainder of 5e-06.
