We're dividing 83473660 by 809 
The aim is to understand the frequency of 809 in 83473660.

Going ahead to step 1:
When dividing 8 by 809, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 809

Let's proceed to step 2:
809 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 809

Step 3:
When dividing 834 by 809, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 809 from 834 and we're left with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 809

Moving on to step 4:
809 can be fit into 257 0 times, resulting in a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 257, we end up with 257.
Take the next digit (3) from the dividend and append it to 257, then repeat: 2573 / 809

Advancing to step 5:
2573 divided by 809 is 3 with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 2427 from 2573 to get 146.
Fetch the next digit (6) from the dividend, attach it to 146 and continue: 1466 / 809

Let's proceed to step 6:
1466 divided by 809 is 1 with a remainder of 657.
Write down 1 as next digit of the result. 
Result so far: 1031.0
Subtracting 809 from 1466 leaves us with 657.
Bring next digit (6) of the dividend behind the 657 and repeat the process: 6576 / 809

On to step 7:
809 can be fit into 6576 8 times, resulting in a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 10318.0
The remainder is 104 after subtracting 6472 from 6576.
Bring next digit (0) of the dividend behind the 104 and repeat the process: 1040 / 809

Going ahead to step 8:
809 goes into 1040 1 times with a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 103181.0
Subtract 809 from 1040 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

On to step 9:
If we divide 2310 by 809, we get 2 and a remainder of 692.
Use 2 as the next digit of our solution. 
Result so far: 103181.2
Deduct 1618 from 2310 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Let's proceed to step 10:
The number 809 fits into 6920 8 times, leaving a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 103181.28
Subtracting 6472 from 6920 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 11:
4480 divided by 809 is 5 with a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 103181.285
The remainder is 435 after subtracting 4045 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 12:
If we divide 4350 by 809, we get 5 and a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 103181.2855
Subtracting 4045 from 4350 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

In conclusion, the division gives 103181.2855 with a balance of 0.00305.
