Let's divide 516661 by 45
We want to figure out the number of times 516661 can be divided by 45.

Step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 45

Let's proceed to step 2:
45 can be fit into 51 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 51 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 45

On to step 3:
The number 45 fits into 66 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 45 from 66 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 45

Let's proceed to step 4:
If we divide 216 by 45, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtract 180 from 216 to get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 45

On to step 5:
When dividing 366 by 45, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1148.0
The remainder is 6 after subtracting 360 from 366.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 45

Advancing to step 6:
The number 45 fits into 61 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 11481.0
Deduct 45 from 61 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 45, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 11481.3
If we subtract 135 from 160, 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:
When dividing 250 by 45, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11481.35
Subtract 225 from 250 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.

On to step 9:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 11481.355
Subtract 225 from 250 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.

After the division, we end up with 11481.355 and a remainder of 0.0025.
