612355 ÷ 15 
Let's see how many times 15 fits into 612355.

On to step 1:
15 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

Step 2:
61 divided by 15 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 60 from 61.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 15

Step 3:
12 divided by 15 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 15

Going ahead to step 4:
When dividing 123 by 15, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 408.0
Subtract 120 from 123 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 15

Advancing to step 5:
15 goes into 35 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 4082.0
Subtract 30 from 35 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 15

Going ahead to step 6:
If we divide 55 by 15, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 40823.0
If we take 45 away from 55, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 40823.6
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 40823.66
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 40823.66, with a leftover of 0.01.
