We divide 40297331 by 307
We want to figure out the number of times 40297331 can be divided by 307.

Let's proceed to step 1:
When dividing 4 by 307, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 307

On to step 2:
40 divided by 307 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 307

Advancing to step 3:
When dividing 402 by 307, we get 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 307 from 402 and we're left with 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 307

Moving on to step 4:
959 divided by 307 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 921 from 959 and we're left with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 307

Going ahead to step 5:
387 divided by 307 is 1 with a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtracting 307 from 387 leaves us with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 307

Going ahead to step 6:
307 can be fit into 803 2 times, resulting in a remainder of 189.
Put 2 as the next digit of the answer. 
Result so far: 1312.0
If we subtract 614 from 803, we get 189.
Grab the next digit (3) from the dividend, add it to 189, then carry on: 1893 / 307

Step 7:
1893 divided by 307 is 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 13126.0
The remainder is 51 after subtracting 1842 from 1893.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 307

Step 8:
If we divide 511 by 307, we get 1 and a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 131261.0
Deduct 307 from 511 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 9:
2040 divided by 307 is 6 with a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 131261.6
If we subtract 1842 from 2040, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
307 can be fit into 1980 6 times, resulting in a remainder of 138.
The number 6 becomes the next digit in our result. 
Result so far: 131261.66
The remainder is 138 after subtracting 1842 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

In conclusion, the division gives 131261.66 with a balance of 0.138.
