Let's divide 403765 by 45
Let's see how many times 45 fits into 403765.

Going ahead to step 1:
45 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 45

On to step 2:
40 divided by 45 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 45

On to step 3:
When dividing 403 by 45, we get 8 with a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 360 from 403 to get 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 45

Moving on to step 4:
45 goes into 437 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 405 from 437, we get 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 45

On to step 5:
326 divided by 45 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Deduct 315 from 326 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 45

Moving on to step 6:
When dividing 115 by 45, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 8972.0
Subtract 90 from 115 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
If we divide 250 by 45, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8972.5
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8972.55
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 quotient of the division is 8972.55, and the remainder is 0.025.
