18145570 divided by 825 
We want to figure out the number of times 18145570 can be divided by 825.

On to step 1:
The number 825 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 825

Moving on to step 2:
The number 825 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 825

Moving on to step 3:
181 divided by 825 is 0 with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 825

On to step 4:
The number 825 fits into 1814 2 times, leaving a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1650 from 1814 to get 164.
Grab the next digit (5) from the dividend, add it to 164, then carry on: 1645 / 825

Advancing to step 5:
825 can be fit into 1645 1 times, resulting in a remainder of 820.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 825 away from 1645, we end up with 820.
Include the next digit (5) from the dividend after 820, then repeat: 8205 / 825

Moving on to step 6:
The number 825 fits into 8205 9 times, leaving a remainder of 780.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
Subtracting 7425 from 8205 leaves us with 780.
Fetch the next digit (7) from the dividend, attach it to 780 and continue: 7807 / 825

Moving on to step 7:
7807 divided by 825 is 9 with a remainder of 382.
The next digit of our result is 9. 
Result so far: 2199.0
Subtract 7425 from 7807 to get 382.
Grab the next digit (0) from the dividend, add it to 382, then carry on: 3820 / 825

Moving on to step 8:
3820 divided by 825 is 4 with a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 21994.0
If we subtract 3300 from 3820, 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.

Let's proceed to step 9:
If we divide 5200 by 825, we get 6 and a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 21994.6
Subtract 4950 from 5200 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
825 can be fit into 2500 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 21994.63
Subtract 2475 from 2500 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
825 can be fit into 250 0 times, resulting in a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 21994.63
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
If we divide 2500 by 825, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 21994.6303
Deduct 2475 from 2500 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
250 divided by 825 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 21994.6303
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
If we divide 2500 by 825, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 21994.630303
If we subtract 2475 from 2500, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
825 can be fit into 250 0 times, resulting in a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 21994.630303
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 16:
The number 825 fits into 2500 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 21994.63030303
If we take 2475 away from 2500, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 21994.63030303 with a remaining 2.5e-08.
