Let's divide 420197 by 9
We want to divide 420197 by 9.

On to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

Step 2:
The number 9 fits into 42 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 36 from 42 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 9

Going ahead to step 3:
When dividing 60 by 9, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 46.0
Deduct 54 from 60 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 9

Going ahead to step 4:
When dividing 61 by 9, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
The remainder is 7 after subtracting 54 from 61.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Moving on to step 5:
If we divide 79 by 9, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 4668.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Going ahead to step 6:
When dividing 77 by 9, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 46688.0
Subtract 72 from 77 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 9 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46688.5
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 46688.55
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 46688.55 with a balance of 0.005.
