We divide 808429 by 75
The aim is to understand the frequency of 75 in 808429.

Advancing to step 1:
75 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 75

Moving on to step 2:
75 goes into 80 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 80 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 75

Moving on to step 3:
If we divide 58 by 75, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 58 to get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 75

Going ahead to step 4:
If we divide 584 by 75, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 525 away from 584, we end up with 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 75

Advancing to step 5:
75 goes into 592 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 1077.0
Subtract 525 from 592 to get 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 75

Going ahead to step 6:
If we divide 679 by 75, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 10779.0
Deduct 675 from 679 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 75, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10779.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 75, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10779.05
Subtracting 375 from 400 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 10779.053
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 10779.0533
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 10779.0533, and the remainder is 0.00025.
