7349604 ÷ 521 
Our goal is to divide 7349604 by 521.

Step 1:
7 divided by 521 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 521

Let's proceed to step 2:
73 divided by 521 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 521

Advancing to step 3:
If we divide 734 by 521, we get 1 and a remainder of 213.
The next digit of our result is 1. 
Result so far: 1.0
If we take 521 away from 734, we end up with 213.
Include the next digit (9) from the dividend after 213, then repeat: 2139 / 521

Going ahead to step 4:
If we divide 2139 by 521, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2084 from 2139 and we're left with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 521

Advancing to step 5:
521 can be fit into 556 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
The remainder is 35 after subtracting 521 from 556.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 521

Step 6:
When dividing 350 by 521, we get 0 with a remainder of 350.
The next digit of our result is 0. 
Result so far: 1410.0
If we take 0 away from 350, we end up with 350.
Include the next digit (4) from the dividend after 350, then repeat: 3504 / 521

Step 7:
3504 divided by 521 is 6 with a remainder of 378.
The next digit of our result is 6. 
Result so far: 14106.0
The remainder is 378 after subtracting 3126 from 3504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 8:
3780 divided by 521 is 7 with a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 14106.7
Deduct 3647 from 3780 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
The number 521 fits into 1330 2 times, leaving a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 14106.72
Subtracting 1042 from 1330 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 10:
2880 divided by 521 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 14106.725
If we take 2605 away from 2880, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
If we divide 2750 by 521, we get 5 and a remainder of 145.
The next digit of our result is 5. 
Result so far: 14106.7255
Deduct 2605 from 2750 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 14106.7255, with a leftover of 0.00145.
