We're dividing 921021 by 9 
We're looking to find how many times 9 goes into 921021.

On to step 1:
9 divided by 9 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 9

Let's proceed to step 2:
If we divide 2 by 9, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Let's proceed to step 3:
9 can be fit into 21 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 18 from 21 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 9

Step 4:
30 divided by 9 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1023.0
Subtract 27 from 30 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 9

Moving on to step 5:
The number 9 fits into 32 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 10233.0
Subtract 27 from 32 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 9

On to step 6:
When dividing 51 by 9, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 102335.0
If we take 45 away from 51, we end up 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.

Moving on to step 7:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 102335.6
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.

On to step 8:
9 can be fit into 60 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 102335.66
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.

The final outcome is 102335.66, with a leftover of 0.006.
