We look at the division of 3449126 by 521 
We want to figure out the number of times 3449126 can be divided by 521.

Let's proceed to step 1:
521 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 521

On to step 2:
521 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 521

Let's proceed to step 3:
When dividing 344 by 521, we get 0 with a remainder of 344.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 344 and we're left with 344.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 521

Advancing to step 4:
3449 divided by 521 is 6 with a remainder of 323.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3126 from 3449, we get 323.
Include the next digit (1) from the dividend after 323, then repeat: 3231 / 521

Going ahead to step 5:
3231 divided by 521 is 6 with a remainder of 105.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 3126 from 3231 leaves us with 105.
Bring next digit (2) of the dividend behind the 105 and repeat the process: 1052 / 521

Going ahead to step 6:
When dividing 1052 by 521, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
Subtracting 1042 from 1052 leaves us with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 521

Let's proceed to step 7:
106 divided by 521 is 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 6620.0
If we subtract 0 from 106, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 8:
521 goes into 1060 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 6620.2
The remainder is 18 after subtracting 1042 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
The number 521 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 6620.2
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
If we divide 1800 by 521, we get 3 and a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 6620.203
Subtracting 1563 from 1800 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 11:
521 goes into 2370 4 times with a remainder of 286.
The next digit of our result is 4. 
Result so far: 6620.2034
Deduct 2084 from 2370 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 12:
The number 521 fits into 2860 5 times, leaving a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 6620.20345
If we take 2605 away from 2860, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 13:
When dividing 2550 by 521, we get 4 with a remainder of 466.
The number 4 becomes the next digit in our result. 
Result so far: 6620.203454
Deduct 2084 from 2550 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 14:
If we divide 4660 by 521, we get 8 and a remainder of 492.
Use 8 as the next digit of our solution. 
Result so far: 6620.2034548
The remainder is 492 after subtracting 4168 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 15:
When dividing 4920 by 521, we get 9 with a remainder of 231.
Use 9 as the next digit of our solution. 
Result so far: 6620.20345489
Deduct 4689 from 4920 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The quotient of the division is 6620.20345489, and the remainder is 2.31e-07.
