We look at the division of 5203409 by 939 
Our goal is to divide 5203409 by 939.

Going ahead to step 1:
The number 939 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 939

Moving on to step 2:
If we divide 52 by 939, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 939

On to step 3:
The number 939 fits into 520 0 times, leaving a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 520 to get 520.
Append the next digit (3) from the dividend to 520 and continue with: 5203 / 939

Moving on to step 4:
5203 divided by 939 is 5 with a remainder of 508.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4695 from 5203 leaves us with 508.
Take the next digit (4) from the dividend and append it to 508, then repeat: 5084 / 939

Let's proceed to step 5:
When dividing 5084 by 939, we get 5 with a remainder of 389.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 389 after subtracting 4695 from 5084.
Append the next digit (0) from the dividend to 389 and continue with: 3890 / 939

Step 6:
939 can be fit into 3890 4 times, resulting in a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 554.0
Subtracting 3756 from 3890 leaves us with 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 939

Let's proceed to step 7:
The number 939 fits into 1349 1 times, leaving a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 5541.0
Subtracting 939 from 1349 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 8:
If we divide 4100 by 939, we get 4 and a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 5541.4
If we subtract 3756 from 4100, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
3440 divided by 939 is 3 with a remainder of 623.
Write down 3 as next digit of the result. 
Result so far: 5541.43
Subtract 2817 from 3440 to get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 10:
939 can be fit into 6230 6 times, resulting in a remainder of 596.
Record the quotient 6 as the next digit in the result. 
Result so far: 5541.436
Subtracting 5634 from 6230 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 11:
When dividing 5960 by 939, we get 6 with a remainder of 326.
The number 6 becomes the next digit in our result. 
Result so far: 5541.4366
Subtracting 5634 from 5960 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

The final result is 5541.4366 with a remainder of 0.00326.
