We're dividing 12486903 by 617 
We want to divide 12486903 by 617.

Moving on to step 1:
617 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 617

Let's proceed to step 2:
If we divide 12 by 617, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 617

On to step 3:
617 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Fetch the next digit (8) from the dividend, attach it to 124 and continue: 1248 / 617

On to step 4:
617 can be fit into 1248 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1234 from 1248 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 617

Advancing to step 5:
When dividing 146 by 617, we get 0 with a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 146 after subtracting 0 from 146.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 617

Let's proceed to step 6:
617 can be fit into 1469 2 times, resulting in a remainder of 235.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Subtracting 1234 from 1469 leaves us with 235.
Grab the next digit (0) from the dividend, add it to 235, then carry on: 2350 / 617

Moving on to step 7:
617 goes into 2350 3 times with a remainder of 499.
Put 3 as the next digit of the answer. 
Result so far: 2023.0
If we take 1851 away from 2350, we end up with 499.
Fetch the next digit (3) from the dividend, attach it to 499 and continue: 4993 / 617

Let's proceed to step 8:
4993 divided by 617 is 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 20238.0
Deduct 4936 from 4993 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
617 can be fit into 570 0 times, resulting in a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 20238.0
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 10:
5700 divided by 617 is 9 with a remainder of 147.
The next digit of our result is 9. 
Result so far: 20238.09
If we take 5553 away from 5700, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 11:
If we divide 1470 by 617, we get 2 and a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 20238.092
Deduct 1234 from 1470 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 12:
The number 617 fits into 2360 3 times, leaving a remainder of 509.
Write down 3 as next digit of the result. 
Result so far: 20238.0923
The remainder is 509 after subtracting 1851 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 13:
The number 617 fits into 5090 8 times, leaving a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 20238.09238
Subtract 4936 from 5090 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 14:
617 goes into 1540 2 times with a remainder of 306.
The number 2 becomes the next digit in our result. 
Result so far: 20238.092382
Subtracting 1234 from 1540 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 15:
When dividing 3060 by 617, we get 4 with a remainder of 592.
Record the quotient 4 as the next digit in the result. 
Result so far: 20238.0923824
Deduct 2468 from 3060 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 16:
When dividing 5920 by 617, we get 9 with a remainder of 367.
Put 9 as the next digit of the answer. 
Result so far: 20238.09238249
If we subtract 5553 from 5920, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

After the division, we end up with 20238.09238249 and a remainder of 3.67e-07.
