29071102 ÷ 521 
Our goal is to divide 29071102 by 521.

On to step 1:
521 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 521

On to step 2:
29 divided by 521 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 521

On to step 3:
The number 521 fits into 290 0 times, leaving a remainder of 290.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 290 and we're left with 290.
Bring next digit (7) of the dividend behind the 290 and repeat the process: 2907 / 521

Step 4:
The number 521 fits into 2907 5 times, leaving a remainder of 302.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2605 from 2907 and we're left with 302.
Grab the next digit (1) from the dividend, add it to 302, then carry on: 3021 / 521

Let's proceed to step 5:
3021 divided by 521 is 5 with a remainder of 416.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 2605 from 3021 to get 416.
Take the next digit (1) from the dividend and append it to 416, then repeat: 4161 / 521

Advancing to step 6:
The number 521 fits into 4161 7 times, leaving a remainder of 514.
Write down 7 as next digit of the result. 
Result so far: 557.0
The remainder is 514 after subtracting 3647 from 4161.
Take the next digit (0) from the dividend and append it to 514, then repeat: 5140 / 521

Advancing to step 7:
521 goes into 5140 9 times with a remainder of 451.
The number 9 becomes the next digit in our result. 
Result so far: 5579.0
If we subtract 4689 from 5140, we get 451.
Bring next digit (2) of the dividend behind the 451 and repeat the process: 4512 / 521

Going ahead to step 8:
521 can be fit into 4512 8 times, resulting in a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 55798.0
Subtracting 4168 from 4512 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 9:
When dividing 3440 by 521, we get 6 with a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 55798.6
Subtracting 3126 from 3440 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
521 goes into 3140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 55798.66
The remainder is 14 after subtracting 3126 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 55798.66 and a remainder of 0.014.
