37317569 divided by 809 
The aim is to understand the frequency of 809 in 37317569.

Let's proceed to step 1:
809 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 809

Step 2:
If we divide 37 by 809, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 809

Step 3:
373 divided by 809 is 0 with a remainder of 373.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 373 to get 373.
Take the next digit (1) from the dividend and append it to 373, then repeat: 3731 / 809

Advancing to step 4:
If we divide 3731 by 809, we get 4 and a remainder of 495.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3236 from 3731 leaves us with 495.
Bring next digit (7) of the dividend behind the 495 and repeat the process: 4957 / 809

Step 5:
The number 809 fits into 4957 6 times, leaving a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 103 after subtracting 4854 from 4957.
Fetch the next digit (5) from the dividend, attach it to 103 and continue: 1035 / 809

Advancing to step 6:
The number 809 fits into 1035 1 times, leaving a remainder of 226.
The next digit of our result is 1. 
Result so far: 461.0
If we subtract 809 from 1035, we get 226.
Grab the next digit (6) from the dividend, add it to 226, then carry on: 2266 / 809

Let's proceed to step 7:
809 goes into 2266 2 times with a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 4612.0
If we take 1618 away from 2266, we end up with 648.
Grab the next digit (9) from the dividend, add it to 648, then carry on: 6489 / 809

Step 8:
The number 809 fits into 6489 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 46128.0
Subtracting 6472 from 6489 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
170 divided by 809 is 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 46128.0
If we subtract 0 from 170, we get 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 10:
When dividing 1700 by 809, we get 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 46128.02
Subtract 1618 from 1700 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
When dividing 820 by 809, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 46128.021
If we subtract 809 from 820, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
The number 809 fits into 110 0 times, leaving a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 46128.021
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
1100 divided by 809 is 1 with a remainder of 291.
The next digit of our result is 1. 
Result so far: 46128.02101
Subtract 809 from 1100 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 14:
809 can be fit into 2910 3 times, resulting in a remainder of 483.
Write down 3 as next digit of the result. 
Result so far: 46128.021013
If we subtract 2427 from 2910, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Step 15:
4830 divided by 809 is 5 with a remainder of 785.
The number 5 becomes the next digit in our result. 
Result so far: 46128.0210135
Subtracting 4045 from 4830 leaves us with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Let's proceed to step 16:
809 can be fit into 7850 9 times, resulting in a remainder of 569.
Put 9 as the next digit of the answer. 
Result so far: 46128.02101359
If we take 7281 away from 7850, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

The final result is 46128.02101359 with a remainder of 5.69e-07.
