283998 ÷ 45 
We want to figure out the number of times 283998 can be divided by 45.

Advancing to step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 45

Step 2:
If we divide 28 by 45, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 45

Advancing to step 3:
The number 45 fits into 283 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 270 from 283 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 45

Let's proceed to step 4:
The number 45 fits into 139 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 135 from 139 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 45

Step 5:
When dividing 49 by 45, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 631.0
If we take 45 away from 49, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

On to step 6:
The number 45 fits into 48 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 6311.0
The remainder is 3 after subtracting 45 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 45, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6311.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6311.06
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6311.066
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 6311.066, with a leftover of 0.003.
