Let's divide 41521239 by 407
Let's see how many times 407 fits into 41521239.

Advancing to step 1:
407 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 407

Moving on to step 2:
407 can be fit into 41 0 times, resulting in a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 407

Step 3:
If we divide 415 by 407, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 407 from 415 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 407

Going ahead to step 4:
407 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 407

Step 5:
The number 407 fits into 821 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 7 after subtracting 814 from 821.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 407

Going ahead to step 6:
72 divided by 407 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 1020.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 407

Advancing to step 7:
The number 407 fits into 723 1 times, leaving a remainder of 316.
Write down 1 as next digit of the result. 
Result so far: 10201.0
If we take 407 away from 723, we end up with 316.
Bring next digit (9) of the dividend behind the 316 and repeat the process: 3169 / 407

Let's proceed to step 8:
407 can be fit into 3169 7 times, resulting in a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 102017.0
Subtract 2849 from 3169 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
407 goes into 3200 7 times with a remainder of 351.
Write down 7 as next digit of the result. 
Result so far: 102017.7
Subtracting 2849 from 3200 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 10:
The number 407 fits into 3510 8 times, leaving a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 102017.78
If we subtract 3256 from 3510, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 11:
407 goes into 2540 6 times with a remainder of 98.
The next digit of our result is 6. 
Result so far: 102017.786
Deduct 2442 from 2540 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
407 can be fit into 980 2 times, resulting in a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 102017.7862
The remainder is 166 after subtracting 814 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 13:
407 goes into 1660 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 102017.78624
Subtracting 1628 from 1660 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
407 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 102017.78624
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
When dividing 3200 by 407, we get 7 with a remainder of 351.
Record the quotient 7 as the next digit in the result. 
Result so far: 102017.7862407
Deduct 2849 from 3200 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 16:
If we divide 3510 by 407, we get 8 and a remainder of 254.
Put 8 as the next digit of the answer. 
Result so far: 102017.78624078
If we subtract 3256 from 3510, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final result is 102017.78624078 with a remainder of 2.54e-07.
