We're dividing 31440291 by 307 
We want to divide 31440291 by 307.

Let's proceed to step 1:
307 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 307

Let's proceed to step 2:
If we divide 31 by 307, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 307

On to step 3:
When dividing 314 by 307, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 307 from 314 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 307

Moving on to step 4:
74 divided by 307 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 74 and we're left with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 307

Step 5:
The number 307 fits into 740 2 times, leaving a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 614 from 740 to get 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 307

Advancing to step 6:
When dividing 1262 by 307, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1024.0
Subtracting 1228 from 1262 leaves us with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 307

On to step 7:
307 goes into 349 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 10241.0
Subtract 307 from 349 to get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 307

On to step 8:
If we divide 421 by 307, we get 1 and a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 102411.0
The remainder is 114 after subtracting 307 from 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 9:
307 can be fit into 1140 3 times, resulting in a remainder of 219.
Put 3 as the next digit of the answer. 
Result so far: 102411.3
The remainder is 219 after subtracting 921 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 10:
When dividing 2190 by 307, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 102411.37
Subtract 2149 from 2190 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
410 divided by 307 is 1 with a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 102411.371
If we subtract 307 from 410, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 12:
When dividing 1030 by 307, we get 3 with a remainder of 109.
The next digit of our result is 3. 
Result so far: 102411.3713
Subtracting 921 from 1030 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 13:
307 can be fit into 1090 3 times, resulting in a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 102411.37133
The remainder is 169 after subtracting 921 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Our division results in 102411.37133 with a remaining 0.000169.
