We're dividing 63204640 by 312 
We want to divide 63204640 by 312.

Moving on to step 1:
When dividing 6 by 312, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 312

Step 2:
63 divided by 312 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 312

Moving on to step 3:
If we divide 632 by 312, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we take 624 away from 632, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 312

Step 4:
If we divide 80 by 312, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 80, we end up with 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 312

Step 5:
312 goes into 804 2 times with a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 202.0
The remainder is 180 after subtracting 624 from 804.
Append the next digit (6) from the dividend to 180 and continue with: 1806 / 312

On to step 6:
The number 312 fits into 1806 5 times, leaving a remainder of 246.
The next digit of our result is 5. 
Result so far: 2025.0
The remainder is 246 after subtracting 1560 from 1806.
Fetch the next digit (4) from the dividend, attach it to 246 and continue: 2464 / 312

Let's proceed to step 7:
312 goes into 2464 7 times with a remainder of 280.
Put 7 as the next digit of the answer. 
Result so far: 20257.0
Deduct 2184 from 2464 and we're left with 280.
Append the next digit (0) from the dividend to 280 and continue with: 2800 / 312

Moving on to step 8:
When dividing 2800 by 312, we get 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 202578.0
The remainder is 304 after subtracting 2496 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
312 goes into 3040 9 times with a remainder of 232.
Put 9 as the next digit of the answer. 
Result so far: 202578.9
Deduct 2808 from 3040 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 10:
312 goes into 2320 7 times with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 202578.97
Subtracting 2184 from 2320 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 11:
If we divide 1360 by 312, we get 4 and a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 202578.974
Subtracting 1248 from 1360 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
312 goes into 1120 3 times with a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 202578.9743
Subtracting 936 from 1120 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
1840 divided by 312 is 5 with a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 202578.97435
The remainder is 280 after subtracting 1560 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
If we divide 2800 by 312, we get 8 and a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 202578.974358
The remainder is 304 after subtracting 2496 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 15:
312 goes into 3040 9 times with a remainder of 232.
Use 9 as the next digit of our solution. 
Result so far: 202578.9743589
If we take 2808 away from 3040, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 16:
When dividing 2320 by 312, we get 7 with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 202578.97435897
If we subtract 2184 from 2320, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 202578.97435897 and a remainder of 1.36e-07.
