612797 divided by 45 
We want to figure out the number of times 612797 can be divided by 45.

Going ahead to step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

Moving on to step 2:
45 goes into 61 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 61, we end up with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 45

On to step 3:
162 divided by 45 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 135 from 162, we get 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 45

Let's proceed to step 4:
If we divide 277 by 45, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 270 from 277, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 45

On to step 5:
When dividing 79 by 45, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1361.0
Subtract 45 from 79 to get 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 45

Step 6:
If we divide 347 by 45, we get 7 and a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 13617.0
Subtracting 315 from 347 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
45 goes into 320 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 13617.7
If we take 315 away from 320, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 13617.71
Deduct 45 from 50 and we're left with 5.
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:
When dividing 50 by 45, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 13617.711
If we subtract 45 from 50, 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.

After the division, we end up with 13617.711 and a remainder of 0.0005.
