We divide 850246 by 9
The aim is to understand the frequency of 9 in 850246.

Advancing to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 9

Step 2:
The number 9 fits into 85 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 4 after subtracting 81 from 85.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 9

On to step 3:
If we divide 40 by 9, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtract 36 from 40 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 9

On to step 4:
9 goes into 42 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 944.0
If we subtract 36 from 42, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 9

Advancing to step 5:
When dividing 64 by 9, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 9447.0
If we take 63 away from 64, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 9

On to step 6:
16 divided by 9 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 94471.0
If we subtract 9 from 16, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
9 goes into 70 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 94471.7
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 94471.77
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 94471.77, and the remainder is 0.007.
