830869 ÷ 45 
Our goal is to divide 830869 by 45.

Moving on to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 45

Advancing to step 2:
When dividing 83 by 45, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 45 from 83, we get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 45

Step 3:
380 divided by 45 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 20 after subtracting 360 from 380.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 45

Moving on to step 4:
45 can be fit into 208 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 184.0
Subtracting 180 from 208 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 45

Let's proceed to step 5:
When dividing 286 by 45, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1846.0
If we subtract 270 from 286, we get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 45

Going ahead to step 6:
45 goes into 169 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18463.0
Deduct 135 from 169 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
If we divide 340 by 45, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 18463.7
If we subtract 315 from 340, 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 8:
250 divided by 45 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 18463.75
Subtract 225 from 250 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.

Step 9:
45 goes into 250 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 18463.755
The remainder is 25 after subtracting 225 from 250.
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 18463.755 with a remaining 0.0025.
