We're dividing 61945295 by 809 
The aim is to understand the frequency of 809 in 61945295.

On to step 1:
809 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 809

Step 2:
The number 809 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 809

Step 3:
809 can be fit into 619 0 times, resulting in a remainder of 619.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 619, we end up with 619.
Take the next digit (4) from the dividend and append it to 619, then repeat: 6194 / 809

Moving on to step 4:
When dividing 6194 by 809, we get 7 with a remainder of 531.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 5663 from 6194, we get 531.
Take the next digit (5) from the dividend and append it to 531, then repeat: 5315 / 809

Advancing to step 5:
If we divide 5315 by 809, we get 6 and a remainder of 461.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 4854 from 5315 to get 461.
Take the next digit (2) from the dividend and append it to 461, then repeat: 4612 / 809

Let's proceed to step 6:
If we divide 4612 by 809, we get 5 and a remainder of 567.
Write down 5 as next digit of the result. 
Result so far: 765.0
Subtract 4045 from 4612 to get 567.
Append the next digit (9) from the dividend to 567 and continue with: 5679 / 809

On to step 7:
809 goes into 5679 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7657.0
Deduct 5663 from 5679 and we're left with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 809

Moving on to step 8:
809 goes into 165 0 times with a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 76570.0
Deduct 0 from 165 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
The number 809 fits into 1650 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 76570.2
If we subtract 1618 from 1650, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 809, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 76570.2
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 11:
If we divide 3200 by 809, we get 3 and a remainder of 773.
Write down 3 as next digit of the result. 
Result so far: 76570.203
If we subtract 2427 from 3200, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Advancing to step 12:
809 goes into 7730 9 times with a remainder of 449.
The number 9 becomes the next digit in our result. 
Result so far: 76570.2039
Subtracting 7281 from 7730 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Step 13:
809 goes into 4490 5 times with a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 76570.20395
Subtracting 4045 from 4490 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 14:
If we divide 4450 by 809, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 76570.203955
If we subtract 4045 from 4450, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

After the division, we end up with 76570.203955 and a remainder of 4.05e-05.
