859499 ÷ 45 
We want to divide 859499 by 45.

On to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 45

Going ahead to step 2:
45 can be fit into 85 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 40 after subtracting 45 from 85.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 45

Moving on to step 3:
If we divide 409 by 45, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 405 from 409 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 45

Step 4:
45 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Subtract 0 from 44 to get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 45

Moving on to step 5:
When dividing 449 by 45, we get 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 1909.0
The remainder is 44 after subtracting 405 from 449.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 45

On to step 6:
If we divide 449 by 45, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 19099.0
Deduct 405 from 449 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
45 goes into 440 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 19099.9
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
45 goes into 350 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 19099.97
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 19099.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 19099.977, and the remainder is 0.0035.
