We divide 788821 by 10
The aim is to understand the frequency of 10 in 788821.

On to step 1:
If we divide 7 by 10, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 10

Advancing to step 2:
The number 10 fits into 78 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 70 from 78 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 10

Step 3:
If we divide 88 by 10, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 8 after subtracting 80 from 88.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 10

Moving on to step 4:
10 can be fit into 88 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 788.0
Subtract 80 from 88 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 10

Moving on to step 5:
10 can be fit into 82 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7888.0
If we take 80 away from 82, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Advancing to step 6:
10 can be fit into 21 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 78882.0
The remainder is 1 after subtracting 20 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 10, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 78882.1
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 78882.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 78882.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 78882.1, with a leftover of 0.0.
