We're dividing 783186 by 9 
The aim is to understand the frequency of 9 in 783186.

Step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 9

Going ahead to step 2:
The number 9 fits into 78 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 72 from 78 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 9

Step 3:
9 can be fit into 63 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 63 away from 63, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 9

Moving on to step 4:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 870.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 9

Step 5:
When dividing 18 by 9, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 8702.0
If we subtract 18 from 18, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 9

Step 6:
9 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 87020.0
Subtract 0 from 6 to get 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:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 87020.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 87020.66
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 87020.66 with a balance of 0.006.
