615188 divided by 40 
Our goal is to divide 615188 by 40.

Moving on to step 1:
The number 40 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 40

Moving on to step 2:
61 divided by 40 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 40 from 61, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 40

Let's proceed to step 3:
If we divide 215 by 40, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 200 from 215, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 40

Moving on to step 4:
If we divide 151 by 40, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 153.0
Subtract 120 from 151 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 40

Advancing to step 5:
40 can be fit into 318 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1537.0
Subtracting 280 from 318 leaves us with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 40

On to step 6:
The number 40 fits into 388 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 15379.0
Deduct 360 from 388 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
280 divided by 40 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 15379.7
If we take 280 away from 280, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15379.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 15379.7
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15379.7, with a leftover of 0.0.
