Let's divide 921748 by 45
We want to figure out the number of times 921748 can be divided by 45.

Moving on to step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 45

Going ahead to step 2:
If we divide 92 by 45, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 2 after subtracting 90 from 92.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 45

Going ahead to step 3:
If we divide 21 by 45, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 45

Going ahead to step 4:
If we divide 217 by 45, we get 4 and a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 204.0
Subtracting 180 from 217 leaves us with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 45

Let's proceed to step 5:
When dividing 374 by 45, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2048.0
Subtract 360 from 374 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 45

On to step 6:
148 divided by 45 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 20483.0
If we take 135 away from 148, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
45 can be fit into 130 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 20483.2
If we subtract 90 from 130, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 20483.28
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 20483.288
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 20483.288 and a remainder of 0.004.
