836845 ÷ 45 
We want to figure out the number of times 836845 can be divided by 45.

On to step 1:
If we divide 8 by 45, we get 0 and 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

Advancing to step 2:
When dividing 83 by 45, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 83, we end up with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 45

On to step 3:
When dividing 386 by 45, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 360 from 386 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 45

On to step 4:
If we divide 268 by 45, we get 5 and a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Deduct 225 from 268 and we're left with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 45

Advancing to step 5:
If we divide 434 by 45, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1859.0
If we take 405 away from 434, we end up with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 45

Let's proceed to step 6:
The number 45 fits into 295 6 times, leaving a remainder of 25.
The next digit of our result is 6. 
Result so far: 18596.0
If we take 270 away from 295, 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.

Moving on to step 7:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 18596.5
If we take 225 away from 250, 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.

Let's proceed to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 18596.55
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.

The final outcome is 18596.55, with a leftover of 0.025.
