We look at the division of 15407863 by 617 
Let's see how many times 617 fits into 15407863.

Advancing to step 1:
617 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 617

On to step 2:
617 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 617

Advancing to step 3:
154 divided by 617 is 0 with a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 617

Step 4:
617 goes into 1540 2 times with a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 306 after subtracting 1234 from 1540.
Include the next digit (7) from the dividend after 306, then repeat: 3067 / 617

Advancing to step 5:
617 goes into 3067 4 times with a remainder of 599.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 2468 from 3067 to get 599.
Take the next digit (8) from the dividend and append it to 599, then repeat: 5998 / 617

Advancing to step 6:
617 goes into 5998 9 times with a remainder of 445.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
If we subtract 5553 from 5998, we get 445.
Grab the next digit (6) from the dividend, add it to 445, then carry on: 4456 / 617

Advancing to step 7:
If we divide 4456 by 617, we get 7 and a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 2497.0
Subtracting 4319 from 4456 leaves us with 137.
Bring next digit (3) of the dividend behind the 137 and repeat the process: 1373 / 617

Let's proceed to step 8:
If we divide 1373 by 617, we get 2 and a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 24972.0
If we take 1234 away from 1373, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
When dividing 1390 by 617, we get 2 with a remainder of 156.
The next digit of our result is 2. 
Result so far: 24972.2
Subtract 1234 from 1390 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 10:
1560 divided by 617 is 2 with a remainder of 326.
The next digit of our result is 2. 
Result so far: 24972.22
The remainder is 326 after subtracting 1234 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

After the division, we end up with 24972.22 and a remainder of 0.326.
