We're dividing 801596 by 45 
We want to figure out the number of times 801596 can be divided by 45.

Step 1:
45 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
80 divided by 45 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 80, we end up with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 45

Let's proceed to step 3:
45 goes into 351 7 times with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 315 from 351 to get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 45

Let's proceed to step 4:
The number 45 fits into 365 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
The remainder is 5 after subtracting 360 from 365.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 45

Moving on to step 5:
45 goes into 59 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1781.0
If we subtract 45 from 59, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 45

Step 6:
45 goes into 146 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 17813.0
Deduct 135 from 146 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 45 fits into 110 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 17813.2
If we subtract 90 from 110, 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.

Going ahead to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 17813.24
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 17813.244
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 17813.244 with a balance of 0.002.
