Let's divide 421774 by 45
Our goal is to divide 421774 by 45.

Let's proceed to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 45

Let's proceed to step 2:
The number 45 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 45

Advancing to step 3:
The number 45 fits into 421 9 times, leaving a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 405 from 421, we get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 45

Step 4:
45 goes into 167 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Deduct 135 from 167 and we're left with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 45

On to step 5:
If we divide 327 by 45, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 937.0
If we subtract 315 from 327, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 45

Step 6:
45 can be fit into 124 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 9372.0
The remainder is 34 after subtracting 90 from 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
45 can be fit into 340 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 9372.7
If we subtract 315 from 340, 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.

Let's proceed to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9372.75
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9372.755
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 9372.755 with a remaining 0.0025.
