We divide 816157 by 45
Our goal is to divide 816157 by 45.

Step 1:
8 divided by 45 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 45

Step 2:
When dividing 81 by 45, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 81 and we're left with 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 45

Step 3:
When dividing 366 by 45, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 360 from 366 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 45

Step 4:
45 can be fit into 61 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Subtracting 45 from 61 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 45

On to step 5:
165 divided by 45 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 1813.0
Subtract 135 from 165 to get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 45

Going ahead to step 6:
If we divide 307 by 45, we get 6 and a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 18136.0
If we subtract 270 from 307, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 45, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 18136.8
If we take 360 away from 370, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 45 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 18136.82
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
45 goes into 100 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 18136.822
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 18136.822 with a balance of 0.001.
