We look at the division of 18245790 by 812 
We're looking to find how many times 812 goes into 18245790.

Going ahead to step 1:
1 divided by 812 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 812

Advancing to step 2:
If we divide 18 by 812, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 812

Step 3:
When dividing 182 by 812, we get 0 with a remainder of 182.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 182 after subtracting 0 from 182.
Bring next digit (4) of the dividend behind the 182 and repeat the process: 1824 / 812

Step 4:
1824 divided by 812 is 2 with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1624 from 1824 to get 200.
Take the next digit (5) from the dividend and append it to 200, then repeat: 2005 / 812

Moving on to step 5:
If we divide 2005 by 812, we get 2 and a remainder of 381.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 1624 from 2005 and we're left with 381.
Include the next digit (7) from the dividend after 381, then repeat: 3817 / 812

Let's proceed to step 6:
If we divide 3817 by 812, we get 4 and a remainder of 569.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtracting 3248 from 3817 leaves us with 569.
Include the next digit (9) from the dividend after 569, then repeat: 5699 / 812

Step 7:
When dividing 5699 by 812, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 2247.0
The remainder is 15 after subtracting 5684 from 5699.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 812

On to step 8:
150 divided by 812 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 22470.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
812 goes into 1500 1 times with a remainder of 688.
The number 1 becomes the next digit in our result. 
Result so far: 22470.1
If we take 812 away from 1500, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 10:
When dividing 6880 by 812, we get 8 with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 22470.18
Subtract 6496 from 6880 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 11:
812 can be fit into 3840 4 times, resulting in a remainder of 592.
The number 4 becomes the next digit in our result. 
Result so far: 22470.184
Subtracting 3248 from 3840 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 12:
The number 812 fits into 5920 7 times, leaving a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 22470.1847
Deduct 5684 from 5920 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 13:
When dividing 2360 by 812, we get 2 with a remainder of 736.
Record the quotient 2 as the next digit in the result. 
Result so far: 22470.18472
Subtracting 1624 from 2360 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 14:
812 goes into 7360 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 22470.184729
Subtract 7308 from 7360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 15:
If we divide 520 by 812, we get 0 and a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 22470.184729
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
The number 812 fits into 5200 6 times, leaving a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 22470.18472906
Subtract 4872 from 5200 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Our division results in 22470.18472906 with a remaining 3.28e-07.
