We look at the division of 99921637 by 9 
We want to figure out the number of times 99921637 can be divided by 9.

Step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 9

Let's proceed to step 2:
When dividing 9 by 9, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 9 from 9 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 9

Let's proceed to step 3:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 9 away from 9, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 9

Going ahead to step 4:
2 divided by 9 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1110.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Moving on to step 5:
If we divide 21 by 9, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 11102.0
Subtract 18 from 21 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 9

Moving on to step 6:
If we divide 36 by 9, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 111024.0
If we take 36 away from 36, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Step 7:
9 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 1110240.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 9

On to step 8:
If we divide 37 by 9, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 11102404.0
The remainder is 1 after subtracting 36 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 9 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11102404.1
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
When dividing 10 by 9, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11102404.11
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 11102404.11 with a balance of 0.001.
