612104 ÷ 45 
Our goal is to divide 612104 by 45.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 45

Going ahead to step 2:
If we divide 61 by 45, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 61 leaves us with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 45

On to step 3:
When dividing 162 by 45, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 135 from 162 leaves us with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 45

Going ahead to step 4:
The number 45 fits into 271 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Deduct 270 from 271 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 45

Going ahead to step 5:
The number 45 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1360.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 45

Going ahead to step 6:
When dividing 104 by 45, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 13602.0
If we subtract 90 from 104, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 45, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 13602.3
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
45 goes into 50 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 13602.31
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 13602.311
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 13602.311, and the remainder is 0.0005.
