40257238 ÷ 934 
We want to divide 40257238 by 934.

Advancing to step 1:
4 divided by 934 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 934

Going ahead to step 2:
The number 934 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 934

Going ahead to step 3:
The number 934 fits into 402 0 times, leaving a remainder of 402.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 402 to get 402.
Fetch the next digit (5) from the dividend, attach it to 402 and continue: 4025 / 934

Moving on to step 4:
When dividing 4025 by 934, we get 4 with a remainder of 289.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3736 from 4025, we get 289.
Include the next digit (7) from the dividend after 289, then repeat: 2897 / 934

Advancing to step 5:
The number 934 fits into 2897 3 times, leaving a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 95 after subtracting 2802 from 2897.
Include the next digit (2) from the dividend after 95, then repeat: 952 / 934

On to step 6:
934 can be fit into 952 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 431.0
Deduct 934 from 952 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 934

Moving on to step 7:
934 goes into 183 0 times with a remainder of 183.
The next digit of our result is 0. 
Result so far: 4310.0
The remainder is 183 after subtracting 0 from 183.
Take the next digit (8) from the dividend and append it to 183, then repeat: 1838 / 934

Step 8:
934 can be fit into 1838 1 times, resulting in a remainder of 904.
Write down 1 as next digit of the result. 
Result so far: 43101.0
If we take 934 away from 1838, we end up with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Going ahead to step 9:
When dividing 9040 by 934, we get 9 with a remainder of 634.
Put 9 as the next digit of the answer. 
Result so far: 43101.9
If we subtract 8406 from 9040, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 10:
934 goes into 6340 6 times with a remainder of 736.
Use 6 as the next digit of our solution. 
Result so far: 43101.96
Subtracting 5604 from 6340 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

On to step 11:
934 can be fit into 7360 7 times, resulting in a remainder of 822.
Write down 7 as next digit of the result. 
Result so far: 43101.967
Subtract 6538 from 7360 to get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Advancing to step 12:
When dividing 8220 by 934, we get 8 with a remainder of 748.
The number 8 becomes the next digit in our result. 
Result so far: 43101.9678
Deduct 7472 from 8220 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Let's proceed to step 13:
934 can be fit into 7480 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 43101.96788
The remainder is 8 after subtracting 7472 from 7480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 43101.96788 and a remainder of 8e-06.
