We look at the division of 99383103 by 858 
Let's see how many times 858 fits into 99383103.

Let's proceed to step 1:
858 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 858

Step 2:
858 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 858

Moving on to step 3:
If we divide 993 by 858, we get 1 and a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 858 from 993 leaves us with 135.
Grab the next digit (8) from the dividend, add it to 135, then carry on: 1358 / 858

Moving on to step 4:
1358 divided by 858 is 1 with a remainder of 500.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 858 from 1358, we get 500.
Append the next digit (3) from the dividend to 500 and continue with: 5003 / 858

Let's proceed to step 5:
When dividing 5003 by 858, we get 5 with a remainder of 713.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 4290 from 5003 leaves us with 713.
Bring next digit (1) of the dividend behind the 713 and repeat the process: 7131 / 858

Moving on to step 6:
The number 858 fits into 7131 8 times, leaving a remainder of 267.
Record the quotient 8 as the next digit in the result. 
Result so far: 1158.0
If we subtract 6864 from 7131, we get 267.
Grab the next digit (0) from the dividend, add it to 267, then carry on: 2670 / 858

Going ahead to step 7:
2670 divided by 858 is 3 with a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 11583.0
Deduct 2574 from 2670 and we're left with 96.
Grab the next digit (3) from the dividend, add it to 96, then carry on: 963 / 858

Step 8:
858 goes into 963 1 times with a remainder of 105.
The next digit of our result is 1. 
Result so far: 115831.0
Subtracting 858 from 963 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
1050 divided by 858 is 1 with a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 115831.1
Deduct 858 from 1050 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
The number 858 fits into 1920 2 times, leaving a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 115831.12
Deduct 1716 from 1920 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 11:
When dividing 2040 by 858, we get 2 with a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 115831.122
If we subtract 1716 from 2040, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The quotient of the division is 115831.122, and the remainder is 0.0324.
