73701924 divided by 809 
The aim is to understand the frequency of 809 in 73701924.

Advancing to step 1:
7 divided by 809 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 809

Advancing to step 2:
The number 809 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 809

Going ahead to step 3:
809 can be fit into 737 0 times, resulting in a remainder of 737.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 737, we end up with 737.
Bring next digit (0) of the dividend behind the 737 and repeat the process: 7370 / 809

Moving on to step 4:
809 can be fit into 7370 9 times, resulting in a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7281 from 7370 to get 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 809

Let's proceed to step 5:
When dividing 891 by 809, we get 1 with a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 809 away from 891, we end up with 82.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 809

Let's proceed to step 6:
If we divide 829 by 809, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 911.0
The remainder is 20 after subtracting 809 from 829.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 809

Let's proceed to step 7:
If we divide 202 by 809, we get 0 and a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 9110.0
If we subtract 0 from 202, we get 202.
Append the next digit (4) from the dividend to 202 and continue with: 2024 / 809

On to step 8:
The number 809 fits into 2024 2 times, leaving a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 91102.0
Subtracting 1618 from 2024 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 9:
If we divide 4060 by 809, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 91102.5
If we subtract 4045 from 4060, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
If we divide 150 by 809, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 91102.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
If we divide 1500 by 809, we get 1 and a remainder of 691.
Use 1 as the next digit of our solution. 
Result so far: 91102.501
The remainder is 691 after subtracting 809 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 12:
809 goes into 6910 8 times with a remainder of 438.
The number 8 becomes the next digit in our result. 
Result so far: 91102.5018
If we take 6472 away from 6910, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 13:
809 goes into 4380 5 times with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 91102.50185
The remainder is 335 after subtracting 4045 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 14:
When dividing 3350 by 809, we get 4 with a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 91102.501854
Subtract 3236 from 3350 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 15:
809 goes into 1140 1 times with a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 91102.5018541
If we subtract 809 from 1140, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 16:
809 goes into 3310 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 91102.50185414
Subtract 3236 from 3310 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 91102.50185414 and a remainder of 7.4e-08.
