99100383 ÷ 122 
We want to figure out the number of times 99100383 can be divided by 122.

On to step 1:
If we divide 9 by 122, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 122

Let's proceed to step 2:
99 divided by 122 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 122

Let's proceed to step 3:
122 can be fit into 991 8 times, resulting in a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 976 away from 991, we end up with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 122

On to step 4:
When dividing 150 by 122, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 122 from 150 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 122

Let's proceed to step 5:
280 divided by 122 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 812.0
Subtract 244 from 280 to get 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 122

Step 6:
122 goes into 363 2 times with a remainder of 119.
Use 2 as the next digit of our solution. 
Result so far: 8122.0
If we take 244 away from 363, we end up with 119.
Append the next digit (8) from the dividend to 119 and continue with: 1198 / 122

Going ahead to step 7:
The number 122 fits into 1198 9 times, leaving a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 81229.0
If we subtract 1098 from 1198, we get 100.
Fetch the next digit (3) from the dividend, attach it to 100 and continue: 1003 / 122

Advancing to step 8:
1003 divided by 122 is 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 812298.0
Subtract 976 from 1003 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
270 divided by 122 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 812298.2
Subtract 244 from 270 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
260 divided by 122 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 812298.22
The remainder is 16 after subtracting 244 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 812298.22 and a remainder of 0.016.
