12860657 divided by 600 
Our goal is to divide 12860657 by 600.

On to step 1:
The number 600 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 600

Step 2:
600 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 600

Advancing to step 3:
If we divide 128 by 600, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Take the next digit (6) from the dividend and append it to 128, then repeat: 1286 / 600

Moving on to step 4:
If we divide 1286 by 600, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1200 from 1286 leaves us with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 600

Step 5:
If we divide 860 by 600, we get 1 and a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 600 away from 860, we end up with 260.
Take the next digit (6) from the dividend and append it to 260, then repeat: 2606 / 600

Advancing to step 6:
2606 divided by 600 is 4 with a remainder of 206.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
The remainder is 206 after subtracting 2400 from 2606.
Include the next digit (5) from the dividend after 206, then repeat: 2065 / 600

Advancing to step 7:
2065 divided by 600 is 3 with a remainder of 265.
The next digit of our result is 3. 
Result so far: 2143.0
If we take 1800 away from 2065, we end up with 265.
Fetch the next digit (7) from the dividend, attach it to 265 and continue: 2657 / 600

Moving on to step 8:
When dividing 2657 by 600, we get 4 with a remainder of 257.
Put 4 as the next digit of the answer. 
Result so far: 21434.0
Subtracting 2400 from 2657 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 9:
2570 divided by 600 is 4 with a remainder of 170.
The next digit of our result is 4. 
Result so far: 21434.4
If we subtract 2400 from 2570, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
When dividing 1700 by 600, we get 2 with a remainder of 500.
The number 2 becomes the next digit in our result. 
Result so far: 21434.42
Subtracting 1200 from 1700 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
600 goes into 5000 8 times with a remainder of 200.
The next digit of our result is 8. 
Result so far: 21434.428
The remainder is 200 after subtracting 4800 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
If we divide 2000 by 600, we get 3 and a remainder of 200.
The next digit of our result is 3. 
Result so far: 21434.4283
Deduct 1800 from 2000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
The number 600 fits into 2000 3 times, leaving a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 21434.42833
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 21434.42833 with a remaining 0.0002.
