We look at the division of 23511037 by 858 
Let's see how many times 858 fits into 23511037.

Step 1:
858 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 858

Step 2:
If we divide 23 by 858, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 858

Going ahead to step 3:
858 goes into 235 0 times with a remainder of 235.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 235 leaves us with 235.
Append the next digit (1) from the dividend to 235 and continue with: 2351 / 858

Advancing to step 4:
2351 divided by 858 is 2 with a remainder of 635.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1716 from 2351 leaves us with 635.
Include the next digit (1) from the dividend after 635, then repeat: 6351 / 858

Advancing to step 5:
If we divide 6351 by 858, we get 7 and a remainder of 345.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 6006 away from 6351, we end up with 345.
Append the next digit (0) from the dividend to 345 and continue with: 3450 / 858

Advancing to step 6:
858 can be fit into 3450 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Subtracting 3432 from 3450 leaves us with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 858

Advancing to step 7:
If we divide 183 by 858, we get 0 and a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 2740.0
Subtracting 0 from 183 leaves us with 183.
Include the next digit (7) from the dividend after 183, then repeat: 1837 / 858

Moving on to step 8:
1837 divided by 858 is 2 with a remainder of 121.
Use 2 as the next digit of our solution. 
Result so far: 27402.0
Subtract 1716 from 1837 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
When dividing 1210 by 858, we get 1 with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 27402.1
If we take 858 away from 1210, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 10:
When dividing 3520 by 858, we get 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 27402.14
If we take 3432 away from 3520, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
880 divided by 858 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 27402.141
Deduct 858 from 880 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
When dividing 220 by 858, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 27402.141
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
The number 858 fits into 2200 2 times, leaving a remainder of 484.
Put 2 as the next digit of the answer. 
Result so far: 27402.14102
Subtract 1716 from 2200 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 14:
858 goes into 4840 5 times with a remainder of 550.
The next digit of our result is 5. 
Result so far: 27402.141025
Subtract 4290 from 4840 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 15:
858 can be fit into 5500 6 times, resulting in a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 27402.1410256
Subtracting 5148 from 5500 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 16:
3520 divided by 858 is 4 with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 27402.14102564
The remainder is 88 after subtracting 3432 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 27402.14102564 with a remainder of 8.8e-08.
