Let's divide 25595226 by 858
Our goal is to divide 25595226 by 858.

Advancing to step 1:
858 can be fit into 2 0 times, resulting in 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.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 858

Let's proceed to step 2:
When dividing 25 by 858, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 858

Moving on to step 3:
858 can be fit into 255 0 times, resulting in a remainder of 255.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Append the next digit (9) from the dividend to 255 and continue with: 2559 / 858

Step 4:
The number 858 fits into 2559 2 times, leaving a remainder of 843.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1716 from 2559 leaves us with 843.
Include the next digit (5) from the dividend after 843, then repeat: 8435 / 858

Moving on to step 5:
8435 divided by 858 is 9 with a remainder of 713.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 7722 from 8435, we get 713.
Fetch the next digit (2) from the dividend, attach it to 713 and continue: 7132 / 858

On to step 6:
7132 divided by 858 is 8 with a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 298.0
Subtract 6864 from 7132 to get 268.
Fetch the next digit (2) from the dividend, attach it to 268 and continue: 2682 / 858

Let's proceed to step 7:
When dividing 2682 by 858, we get 3 with a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 2983.0
If we subtract 2574 from 2682, we get 108.
Bring next digit (6) of the dividend behind the 108 and repeat the process: 1086 / 858

Let's proceed to step 8:
When dividing 1086 by 858, we get 1 with a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 29831.0
Subtract 858 from 1086 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 9:
When dividing 2280 by 858, we get 2 with a remainder of 564.
The next digit of our result is 2. 
Result so far: 29831.2
If we subtract 1716 from 2280, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 10:
The number 858 fits into 5640 6 times, leaving a remainder of 492.
Put 6 as the next digit of the answer. 
Result so far: 29831.26
Subtracting 5148 from 5640 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 11:
If we divide 4920 by 858, we get 5 and a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 29831.265
Subtract 4290 from 4920 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 12:
858 goes into 6300 7 times with a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 29831.2657
Deduct 6006 from 6300 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 13:
If we divide 2940 by 858, we get 3 and a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 29831.26573
If we subtract 2574 from 2940, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 14:
The number 858 fits into 3660 4 times, leaving a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 29831.265734
Subtract 3432 from 3660 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
When dividing 2280 by 858, we get 2 with a remainder of 564.
Write down 2 as next digit of the result. 
Result so far: 29831.2657342
Deduct 1716 from 2280 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 16:
When dividing 5640 by 858, we get 6 with a remainder of 492.
Write down 6 as next digit of the result. 
Result so far: 29831.26573426
If we subtract 5148 from 5640, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The quotient of the division is 29831.26573426, and the remainder is 4.92e-07.
