We divide 73712099 by 9
We want to figure out the number of times 73712099 can be divided by 9.

Moving on to step 1:
7 divided by 9 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 9

Advancing to step 2:
9 can be fit into 73 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 72 from 73 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 9

Step 3:
9 can be fit into 17 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 9 away from 17, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 9

Moving on to step 4:
If we divide 81 by 9, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 819.0
Deduct 81 from 81 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 9

Advancing to step 5:
9 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 8190.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 9

Step 6:
When dividing 20 by 9, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 81902.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Going ahead to step 7:
9 goes into 29 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 819023.0
Subtracting 27 from 29 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 9

Step 8:
9 can be fit into 29 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 8190233.0
Deduct 27 from 29 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 9, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 8190233.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 8190233.22
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 8190233.22, and the remainder is 0.002.
