We divide 87857732 by 817
The aim is to understand the frequency of 817 in 87857732.

On to step 1:
8 divided by 817 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 817

Advancing to step 2:
When dividing 87 by 817, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 817

Going ahead to step 3:
The number 817 fits into 878 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 61 after subtracting 817 from 878.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 817

Going ahead to step 4:
615 divided by 817 is 0 with a remainder of 615.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 615, we get 615.
Take the next digit (7) from the dividend and append it to 615, then repeat: 6157 / 817

Step 5:
817 goes into 6157 7 times with a remainder of 438.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 438 after subtracting 5719 from 6157.
Grab the next digit (7) from the dividend, add it to 438, then carry on: 4387 / 817

Let's proceed to step 6:
817 goes into 4387 5 times with a remainder of 302.
Put 5 as the next digit of the answer. 
Result so far: 1075.0
If we take 4085 away from 4387, we end up with 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 817

Step 7:
3023 divided by 817 is 3 with a remainder of 572.
Use 3 as the next digit of our solution. 
Result so far: 10753.0
If we subtract 2451 from 3023, we get 572.
Bring next digit (2) of the dividend behind the 572 and repeat the process: 5722 / 817

Let's proceed to step 8:
817 goes into 5722 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 107537.0
If we subtract 5719 from 5722, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 817 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 107537.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
300 divided by 817 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 107537.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 107537.0 and a remainder of 0.3.
