We divide 40257931 by 105
Let's see how many times 105 fits into 40257931.

Step 1:
4 divided by 105 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 105

Going ahead to step 2:
105 goes into 40 0 times 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.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 105

Advancing to step 3:
105 goes into 402 3 times with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 87 after subtracting 315 from 402.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 105

Advancing to step 4:
When dividing 875 by 105, we get 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we subtract 840 from 875, we get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 105

Step 5:
When dividing 357 by 105, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 383.0
Subtracting 315 from 357 leaves us with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 105

Let's proceed to step 6:
105 can be fit into 429 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 3834.0
Subtract 420 from 429 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 105

Advancing to step 7:
105 can be fit into 93 0 times, resulting in a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 38340.0
Deduct 0 from 93 and we're left with 93.
Take the next digit (1) from the dividend and append it to 93, then repeat: 931 / 105

On to step 8:
If we divide 931 by 105, we get 8 and a remainder of 91.
The number 8 becomes the next digit in our result. 
Result so far: 383408.0
The remainder is 91 after subtracting 840 from 931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
The number 105 fits into 910 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 383408.8
If we take 840 away from 910, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 105, we get 6 and a remainder of 70.
The next digit of our result is 6. 
Result so far: 383408.86
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
The number 105 fits into 700 6 times, leaving a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 383408.866
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 383408.866 and a remainder of 0.007.
