830445 divided by 45 
We want to figure out the number of times 830445 can be divided by 45.

Going ahead to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 45

Step 2:
45 can be fit into 83 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 83, we end up with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 45

Step 3:
45 goes into 380 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 360 from 380 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 45

Step 4:
204 divided by 45 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 180 away from 204, we end up with 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 45

Advancing to step 5:
244 divided by 45 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 1845.0
Subtract 225 from 244 to get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 45

Moving on to step 6:
The number 45 fits into 195 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 18454.0
If we subtract 180 from 195, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 18454.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 18454.33
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 18454.33, with a leftover of 0.015.
