We look at the division of 39249261 by 907 
We want to figure out the number of times 39249261 can be divided by 907.

Moving on to step 1:
The number 907 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 907

Going ahead to step 2:
The number 907 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 907

Advancing to step 3:
907 can be fit into 392 0 times, resulting in a remainder of 392.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 392 leaves us with 392.
Take the next digit (4) from the dividend and append it to 392, then repeat: 3924 / 907

Going ahead to step 4:
When dividing 3924 by 907, we get 4 with a remainder of 296.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3628 away from 3924, we end up with 296.
Fetch the next digit (9) from the dividend, attach it to 296 and continue: 2969 / 907

Going ahead to step 5:
If we divide 2969 by 907, we get 3 and a remainder of 248.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 2721 from 2969 leaves us with 248.
Take the next digit (2) from the dividend and append it to 248, then repeat: 2482 / 907

Going ahead to step 6:
The number 907 fits into 2482 2 times, leaving a remainder of 668.
Use 2 as the next digit of our solution. 
Result so far: 432.0
Subtract 1814 from 2482 to get 668.
Append the next digit (6) from the dividend to 668 and continue with: 6686 / 907

Let's proceed to step 7:
6686 divided by 907 is 7 with a remainder of 337.
The next digit of our result is 7. 
Result so far: 4327.0
Deduct 6349 from 6686 and we're left with 337.
Take the next digit (1) from the dividend and append it to 337, then repeat: 3371 / 907

Step 8:
If we divide 3371 by 907, we get 3 and a remainder of 650.
The number 3 becomes the next digit in our result. 
Result so far: 43273.0
Deduct 2721 from 3371 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 9:
If we divide 6500 by 907, we get 7 and a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 43273.7
Subtract 6349 from 6500 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 10:
1510 divided by 907 is 1 with a remainder of 603.
Use 1 as the next digit of our solution. 
Result so far: 43273.71
If we subtract 907 from 1510, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 11:
If we divide 6030 by 907, we get 6 and a remainder of 588.
Write down 6 as next digit of the result. 
Result so far: 43273.716
If we subtract 5442 from 6030, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 12:
907 goes into 5880 6 times with a remainder of 438.
Use 6 as the next digit of our solution. 
Result so far: 43273.7166
The remainder is 438 after subtracting 5442 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

After the division, we end up with 43273.7166 and a remainder of 0.00438.
