919171 divided by 45 
Let's see how many times 45 fits into 919171.

Advancing to step 1:
9 divided by 45 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 45

Advancing to step 2:
The number 45 fits into 91 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 90 from 91, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 45

Moving on to step 3:
If we divide 19 by 45, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 19 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 45

Going ahead to step 4:
When dividing 191 by 45, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 204.0
Deduct 180 from 191 and we're left with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 45

Advancing to step 5:
The number 45 fits into 117 2 times, leaving a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 2042.0
If we subtract 90 from 117, we get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 45

Step 6:
45 goes into 271 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 20426.0
Deduct 270 from 271 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 45 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20426.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 45 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 20426.02
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 20426.022
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 20426.022 with a remainder of 0.001.
