807365 ÷ 45 
We're looking to find how many times 45 goes into 807365.

Advancing to step 1:
The number 45 fits into 8 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

Advancing to step 2:
If we divide 80 by 45, we get 1 and a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 80 and we're left with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 45

Moving on to step 3:
45 can be fit into 357 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 315 away from 357, we end up with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 45

Advancing to step 4:
When dividing 423 by 45, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 179.0
Deduct 405 from 423 and we're left with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 45

Going ahead to step 5:
If we divide 186 by 45, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1794.0
Subtracting 180 from 186 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 45

Moving on to step 6:
When dividing 65 by 45, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 17941.0
Subtract 45 from 65 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 17941.4
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
45 goes into 200 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17941.44
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 17941.44 and a remainder of 0.02.
