We're dividing 11245834 by 858 
Our goal is to divide 11245834 by 858.

Let's proceed to step 1:
1 divided by 858 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 858

Let's proceed to step 2:
When dividing 11 by 858, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 858

Going ahead to step 3:
The number 858 fits into 112 0 times, leaving a remainder of 112.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 112 leaves us with 112.
Include the next digit (4) from the dividend after 112, then repeat: 1124 / 858

Moving on to step 4:
1124 divided by 858 is 1 with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 858 from 1124, we get 266.
Include the next digit (5) from the dividend after 266, then repeat: 2665 / 858

Advancing to step 5:
858 goes into 2665 3 times with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 2574 from 2665 and we're left with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 858

Moving on to step 6:
918 divided by 858 is 1 with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we subtract 858 from 918, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 858

Let's proceed to step 7:
858 can be fit into 603 0 times, resulting in a remainder of 603.
Write down 0 as next digit of the result. 
Result so far: 1310.0
If we subtract 0 from 603, we get 603.
Bring next digit (4) of the dividend behind the 603 and repeat the process: 6034 / 858

Going ahead to step 8:
The number 858 fits into 6034 7 times, leaving a remainder of 28.
The next digit of our result is 7. 
Result so far: 13107.0
Deduct 6006 from 6034 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
858 can be fit into 280 0 times, resulting in a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 13107.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
858 goes into 2800 3 times with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 13107.03
The remainder is 226 after subtracting 2574 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 11:
The number 858 fits into 2260 2 times, leaving a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 13107.032
Deduct 1716 from 2260 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 12:
When dividing 5440 by 858, we get 6 with a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 13107.0326
If we take 5148 away from 5440, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
858 can be fit into 2920 3 times, resulting in a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 13107.03263
Subtract 2574 from 2920 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 14:
If we divide 3460 by 858, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 13107.032634
Deduct 3432 from 3460 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
When dividing 280 by 858, we get 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 13107.032634
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
When dividing 2800 by 858, we get 3 with a remainder of 226.
The next digit of our result is 3. 
Result so far: 13107.03263403
Subtract 2574 from 2800 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 13107.03263403, with a leftover of 2.26e-07.
