We're dividing 801401 by 45 
We want to figure out the number of times 801401 can be divided by 45.

Going ahead to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 45

Let's proceed to step 2:
If we divide 80 by 45, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 80 leaves us with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 45

Advancing to step 3:
When dividing 351 by 45, we get 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 17.0
If we take 315 away from 351, we end up with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 45

Going ahead to step 4:
364 divided by 45 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 178.0
If we subtract 360 from 364, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 45

Going ahead to step 5:
The number 45 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1780.0
If we subtract 0 from 40, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 45

Advancing to step 6:
When dividing 401 by 45, we get 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 17808.0
Subtracting 360 from 401 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
When dividing 410 by 45, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 17808.9
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 17808.91
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 17808.911
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 17808.911, and the remainder is 0.0005.
