We divide 31212007 by 304
We want to divide 31212007 by 304.

Step 1:
If we divide 3 by 304, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 304

Going ahead to step 2:
When dividing 31 by 304, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 304

On to step 3:
When dividing 312 by 304, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 304 from 312, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 304

Let's proceed to step 4:
304 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 81, we get 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 304

Step 5:
812 divided by 304 is 2 with a remainder of 204.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 608 from 812 and we're left with 204.
Append the next digit (0) from the dividend to 204 and continue with: 2040 / 304

Step 6:
304 can be fit into 2040 6 times, resulting in a remainder of 216.
Record the quotient 6 as the next digit in the result. 
Result so far: 1026.0
Deduct 1824 from 2040 and we're left with 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 304

Going ahead to step 7:
304 can be fit into 2160 7 times, resulting in a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 10267.0
If we take 2128 away from 2160, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 304

Moving on to step 8:
327 divided by 304 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 102671.0
Subtract 304 from 327 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
304 goes into 230 0 times with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 102671.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
If we divide 2300 by 304, we get 7 and a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 102671.07
If we subtract 2128 from 2300, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 11:
304 can be fit into 1720 5 times, resulting in a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 102671.075
Subtracting 1520 from 1720 leaves us 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.

Let's proceed to step 12:
When dividing 2000 by 304, we get 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 102671.0756
If we subtract 1824 from 2000, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
1760 divided by 304 is 5 with a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 102671.07565
The remainder is 240 after subtracting 1520 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
When dividing 2400 by 304, we get 7 with a remainder of 272.
The next digit of our result is 7. 
Result so far: 102671.075657
Subtract 2128 from 2400 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 15:
304 goes into 2720 8 times with a remainder of 288.
The next digit of our result is 8. 
Result so far: 102671.0756578
If we subtract 2432 from 2720, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 16:
If we divide 2880 by 304, we get 9 and a remainder of 144.
The number 9 becomes the next digit in our result. 
Result so far: 102671.07565789
The remainder is 144 after subtracting 2736 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 102671.07565789 with a remaining 1.44e-07.
