Let's divide 3980908 by 538
We're looking to find how many times 538 goes into 3980908.

Step 1:
When dividing 3 by 538, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 538

Let's proceed to step 2:
When dividing 39 by 538, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 538

Let's proceed to step 3:
When dividing 398 by 538, we get 0 with a remainder of 398.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Append the next digit (0) from the dividend to 398 and continue with: 3980 / 538

Step 4:
The number 538 fits into 3980 7 times, leaving a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 3766 from 3980 and we're left with 214.
Grab the next digit (9) from the dividend, add it to 214, then carry on: 2149 / 538

Moving on to step 5:
538 goes into 2149 3 times with a remainder of 535.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 1614 from 2149 leaves us with 535.
Include the next digit (0) from the dividend after 535, then repeat: 5350 / 538

Step 6:
The number 538 fits into 5350 9 times, leaving a remainder of 508.
Record the quotient 9 as the next digit in the result. 
Result so far: 739.0
Deduct 4842 from 5350 and we're left with 508.
Include the next digit (8) from the dividend after 508, then repeat: 5088 / 538

Moving on to step 7:
When dividing 5088 by 538, we get 9 with a remainder of 246.
Put 9 as the next digit of the answer. 
Result so far: 7399.0
Subtract 4842 from 5088 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 8:
2460 divided by 538 is 4 with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 7399.4
The remainder is 308 after subtracting 2152 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 9:
538 can be fit into 3080 5 times, resulting in a remainder of 390.
The next digit of our result is 5. 
Result so far: 7399.45
If we subtract 2690 from 3080, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
If we divide 3900 by 538, we get 7 and a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 7399.457
The remainder is 134 after subtracting 3766 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 11:
When dividing 1340 by 538, we get 2 with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 7399.4572
Deduct 1076 from 1340 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
538 goes into 2640 4 times with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 7399.45724
Subtracting 2152 from 2640 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 13:
If we divide 4880 by 538, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 7399.457249
Subtracting 4842 from 4880 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
When dividing 380 by 538, we get 0 with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 7399.457249
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
The number 538 fits into 3800 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7399.45724907
Deduct 3766 from 3800 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 7399.45724907 and a remainder of 3.4e-08.
