We divide 87398755 by 802
The aim is to understand the frequency of 802 in 87398755.

Advancing to step 1:
802 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 802

Step 2:
802 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 802

Let's proceed to step 3:
When dividing 873 by 802, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 802 from 873 leaves us with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 802

Step 4:
When dividing 719 by 802, we get 0 with a remainder of 719.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 719, we get 719.
Grab the next digit (8) from the dividend, add it to 719, then carry on: 7198 / 802

Step 5:
The number 802 fits into 7198 8 times, leaving a remainder of 782.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 6416 from 7198 leaves us with 782.
Append the next digit (7) from the dividend to 782 and continue with: 7827 / 802

Step 6:
When dividing 7827 by 802, we get 9 with a remainder of 609.
The next digit of our result is 9. 
Result so far: 1089.0
If we subtract 7218 from 7827, we get 609.
Take the next digit (5) from the dividend and append it to 609, then repeat: 6095 / 802

Going ahead to step 7:
802 goes into 6095 7 times with a remainder of 481.
Write down 7 as next digit of the result. 
Result so far: 10897.0
If we take 5614 away from 6095, we end up with 481.
Take the next digit (5) from the dividend and append it to 481, then repeat: 4815 / 802

Moving on to step 8:
802 can be fit into 4815 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 108976.0
Subtracting 4812 from 4815 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
802 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 108976.0
If we subtract 0 from 30, we 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.

Let's proceed to step 10:
The number 802 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 108976.0
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.

The final result is 108976.0 with a remainder of 0.3.
