We divide 830915 by 45
Let's see how many times 45 fits into 830915.

Step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 45

Step 2:
If we divide 83 by 45, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 83 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 45

Moving on to step 3:
45 can be fit into 380 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 360 from 380 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 45

Going ahead to step 4:
209 divided by 45 is 4 with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 180 from 209, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 45

Going ahead to step 5:
45 can be fit into 291 6 times, resulting in a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 1846.0
Deduct 270 from 291 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 45

Advancing to step 6:
The number 45 fits into 215 4 times, leaving a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 18464.0
If we take 180 away from 215, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
45 goes into 350 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 18464.7
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 18464.77
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 18464.77 with a remaining 0.035.
