We're dividing 39426361 by 501 
The aim is to understand the frequency of 501 in 39426361.

Step 1:
When dividing 3 by 501, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 501

On to step 2:
When dividing 39 by 501, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 501

Step 3:
The number 501 fits into 394 0 times, leaving a remainder of 394.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Bring next digit (2) of the dividend behind the 394 and repeat the process: 3942 / 501

Let's proceed to step 4:
3942 divided by 501 is 7 with a remainder of 435.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 435 after subtracting 3507 from 3942.
Take the next digit (6) from the dividend and append it to 435, then repeat: 4356 / 501

Going ahead to step 5:
If we divide 4356 by 501, we get 8 and a remainder of 348.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 348 after subtracting 4008 from 4356.
Include the next digit (3) from the dividend after 348, then repeat: 3483 / 501

Let's proceed to step 6:
When dividing 3483 by 501, we get 6 with a remainder of 477.
Record the quotient 6 as the next digit in the result. 
Result so far: 786.0
If we subtract 3006 from 3483, we get 477.
Bring next digit (6) of the dividend behind the 477 and repeat the process: 4776 / 501

Going ahead to step 7:
If we divide 4776 by 501, we get 9 and a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 7869.0
Deduct 4509 from 4776 and we're left with 267.
Include the next digit (1) from the dividend after 267, then repeat: 2671 / 501

Advancing to step 8:
501 can be fit into 2671 5 times, resulting in a remainder of 166.
The next digit of our result is 5. 
Result so far: 78695.0
The remainder is 166 after subtracting 2505 from 2671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 9:
When dividing 1660 by 501, we get 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 78695.3
Subtracting 1503 from 1660 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 10:
1570 divided by 501 is 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 78695.33
If we subtract 1503 from 1570, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 78695.33, and the remainder is 0.067.
