We divide 839806 by 10
The aim is to understand the frequency of 10 in 839806.

Moving on to step 1:
When dividing 8 by 10, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 10

On to step 2:
83 divided by 10 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 80 from 83 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 10

Let's proceed to step 3:
10 goes into 39 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
If we take 30 away from 39, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 10

Step 4:
98 divided by 10 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
If we take 90 away from 98, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 10

Moving on to step 5:
80 divided by 10 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8398.0
The remainder is 0 after subtracting 80 from 80.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 10

On to step 6:
If we divide 6 by 10, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 83980.0
Subtracting 0 from 6 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 10 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 83980.6
Deduct 60 from 60 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.

Going ahead to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 83980.6
Subtract 0 from 0 to 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.

On to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 83980.6
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.

The final result is 83980.6 with a remainder of 0.0.
