Let's divide 612887 by 45
We're looking to find how many times 45 goes into 612887.

Going ahead to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

Advancing to step 2:
45 can be fit into 61 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 61 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 45

Going ahead to step 3:
45 can be fit into 162 3 times, resulting in 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.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 45

Let's proceed to step 4:
If we divide 278 by 45, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 270 from 278 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 45

On to step 5:
If we divide 88 by 45, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 1361.0
Deduct 45 from 88 and we're left with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 45

On to step 6:
The number 45 fits into 437 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 13619.0
The remainder is 32 after subtracting 405 from 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 45 fits into 320 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 13619.7
The remainder is 5 after subtracting 315 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
45 goes into 50 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 13619.71
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.

Advancing to step 9:
45 goes into 50 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 13619.711
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.

The final outcome is 13619.711, with a leftover of 0.0005.
