23215252 ÷ 858 
Our goal is to divide 23215252 by 858.

Let's proceed to step 1:
If we divide 2 by 858, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 858

Let's proceed to step 2:
858 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 858

Step 3:
When dividing 232 by 858, we get 0 with a remainder of 232.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 232, we end up with 232.
Take the next digit (1) from the dividend and append it to 232, then repeat: 2321 / 858

Going ahead to step 4:
858 can be fit into 2321 2 times, resulting in a remainder of 605.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1716 away from 2321, we end up with 605.
Grab the next digit (5) from the dividend, add it to 605, then carry on: 6055 / 858

Step 5:
If we divide 6055 by 858, we get 7 and a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 6006 from 6055 to get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 858

Step 6:
858 goes into 492 0 times with a remainder of 492.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we subtract 0 from 492, we get 492.
Take the next digit (5) from the dividend and append it to 492, then repeat: 4925 / 858

Step 7:
When dividing 4925 by 858, we get 5 with a remainder of 635.
Put 5 as the next digit of the answer. 
Result so far: 2705.0
If we subtract 4290 from 4925, we get 635.
Append the next digit (2) from the dividend to 635 and continue with: 6352 / 858

Moving on to step 8:
When dividing 6352 by 858, we get 7 with a remainder of 346.
The number 7 becomes the next digit in our result. 
Result so far: 27057.0
If we take 6006 away from 6352, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 9:
858 can be fit into 3460 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 27057.4
If we take 3432 away from 3460, we end up 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.

Going ahead to step 10:
858 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 27057.4
If we subtract 0 from 280, we 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.

Let's proceed to step 11:
The number 858 fits into 2800 3 times, leaving a remainder of 226.
The next digit of our result is 3. 
Result so far: 27057.403
Subtracting 2574 from 2800 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 12:
When dividing 2260 by 858, we get 2 with a remainder of 544.
Record the quotient 2 as the next digit in the result. 
Result so far: 27057.4032
Subtract 1716 from 2260 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 13:
5440 divided by 858 is 6 with a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 27057.40326
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.

Going ahead to step 14:
2920 divided by 858 is 3 with a remainder of 346.
Put 3 as the next digit of the answer. 
Result so far: 27057.403263
If we take 2574 away from 2920, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 15:
858 goes into 3460 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 27057.4032634
The remainder is 28 after subtracting 3432 from 3460.
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 16:
280 divided by 858 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 27057.4032634
If we take 0 away from 280, we end up 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.

Our division results in 27057.4032634 with a remaining 2.8e-07.
