Let's divide 37773821 by 501
The aim is to understand the frequency of 501 in 37773821.

On to step 1:
The number 501 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 501

Advancing to step 2:
The number 501 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 501

Going ahead to step 3:
501 can be fit into 377 0 times, resulting in a remainder of 377.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 377 to get 377.
Bring next digit (7) of the dividend behind the 377 and repeat the process: 3777 / 501

Going ahead to step 4:
The number 501 fits into 3777 7 times, leaving a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 3507 from 3777, we get 270.
Append the next digit (3) from the dividend to 270 and continue with: 2703 / 501

On to step 5:
If we divide 2703 by 501, we get 5 and a remainder of 198.
The next digit of our result is 5. 
Result so far: 75.0
The remainder is 198 after subtracting 2505 from 2703.
Grab the next digit (8) from the dividend, add it to 198, then carry on: 1988 / 501

Moving on to step 6:
When dividing 1988 by 501, we get 3 with a remainder of 485.
Record the quotient 3 as the next digit in the result. 
Result so far: 753.0
If we subtract 1503 from 1988, we get 485.
Include the next digit (2) from the dividend after 485, then repeat: 4852 / 501

Step 7:
501 goes into 4852 9 times with a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 7539.0
Deduct 4509 from 4852 and we're left with 343.
Include the next digit (1) from the dividend after 343, then repeat: 3431 / 501

Let's proceed to step 8:
501 can be fit into 3431 6 times, resulting in a remainder of 425.
The next digit of our result is 6. 
Result so far: 75396.0
If we subtract 3006 from 3431, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 9:
501 can be fit into 4250 8 times, resulting in a remainder of 242.
Record the quotient 8 as the next digit in the result. 
Result so far: 75396.8
Subtract 4008 from 4250 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 10:
501 goes into 2420 4 times with a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 75396.84
If we take 2004 away from 2420, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
When dividing 4160 by 501, we get 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 75396.848
Subtracting 4008 from 4160 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
501 goes into 1520 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 75396.8483
If we subtract 1503 from 1520, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
The number 501 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 75396.8483
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
When dividing 1700 by 501, we get 3 with a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 75396.848303
Deduct 1503 from 1700 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 15:
If we divide 1970 by 501, we get 3 and a remainder of 467.
Record the quotient 3 as the next digit in the result. 
Result so far: 75396.8483033
Subtract 1503 from 1970 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final outcome is 75396.8483033, with a leftover of 4.67e-06.
