We look at the division of 3879752 by 909 
We're looking to find how many times 909 goes into 3879752.

Moving on to step 1:
909 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 909

Let's proceed to step 2:
When dividing 38 by 909, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 909

Step 3:
The number 909 fits into 387 0 times, leaving a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 387, we end up with 387.
Append the next digit (9) from the dividend to 387 and continue with: 3879 / 909

Moving on to step 4:
909 can be fit into 3879 4 times, resulting in a remainder of 243.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3636 from 3879 to get 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 909

Step 5:
909 can be fit into 2437 2 times, resulting in a remainder of 619.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 619 after subtracting 1818 from 2437.
Include the next digit (5) from the dividend after 619, then repeat: 6195 / 909

Step 6:
When dividing 6195 by 909, we get 6 with a remainder of 741.
The next digit of our result is 6. 
Result so far: 426.0
If we subtract 5454 from 6195, we get 741.
Include the next digit (2) from the dividend after 741, then repeat: 7412 / 909

Step 7:
7412 divided by 909 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 4268.0
If we subtract 7272 from 7412, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 8:
909 can be fit into 1400 1 times, resulting in a remainder of 491.
The number 1 becomes the next digit in our result. 
Result so far: 4268.1
Subtracting 909 from 1400 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 9:
909 can be fit into 4910 5 times, resulting in a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 4268.15
Subtracting 4545 from 4910 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 10:
909 goes into 3650 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4268.154
Deduct 3636 from 3650 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
When dividing 140 by 909, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 4268.154
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
1400 divided by 909 is 1 with a remainder of 491.
Write down 1 as next digit of the result. 
Result so far: 4268.15401
Deduct 909 from 1400 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Advancing to step 13:
4910 divided by 909 is 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 4268.154015
Subtracting 4545 from 4910 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 14:
When dividing 3650 by 909, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4268.1540154
If we subtract 3636 from 3650, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
909 can be fit into 140 0 times, resulting in a remainder of 140.
The next digit of our result is 0. 
Result so far: 4268.1540154
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 4268.1540154 with a remainder of 1.4e-07.
