We're dividing 401634 by 45 
We want to divide 401634 by 45.

On to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 45

On to step 2:
45 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 45

Advancing to step 3:
The number 45 fits into 401 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 360 from 401 and we're left with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 45

Advancing to step 4:
When dividing 416 by 45, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 405 from 416, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 45

Advancing to step 5:
If we divide 113 by 45, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 892.0
Deduct 90 from 113 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 45

Going ahead to step 6:
The number 45 fits into 234 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 8925.0
If we subtract 225 from 234, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 45, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 8925.2
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 45 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8925.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8925.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8925.2 and a remainder of 0.0.
