Let's divide 70353936 by 521
We want to divide 70353936 by 521.

Going ahead to step 1:
7 divided by 521 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 521

Moving on to step 2:
If we divide 70 by 521, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 521

Let's proceed to step 3:
If we divide 703 by 521, we get 1 and a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 521 away from 703, we end up with 182.
Include the next digit (5) from the dividend after 182, then repeat: 1825 / 521

Moving on to step 4:
1825 divided by 521 is 3 with a remainder of 262.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1563 from 1825 and we're left with 262.
Include the next digit (3) from the dividend after 262, then repeat: 2623 / 521

Advancing to step 5:
If we divide 2623 by 521, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 2605 from 2623 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 521

Moving on to step 6:
521 goes into 189 0 times with a remainder of 189.
The next digit of our result is 0. 
Result so far: 1350.0
Deduct 0 from 189 and we're left with 189.
Append the next digit (3) from the dividend to 189 and continue with: 1893 / 521

On to step 7:
1893 divided by 521 is 3 with a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 13503.0
Subtracting 1563 from 1893 leaves us with 330.
Take the next digit (6) from the dividend and append it to 330, then repeat: 3306 / 521

Moving on to step 8:
521 can be fit into 3306 6 times, resulting in a remainder of 180.
The next digit of our result is 6. 
Result so far: 135036.0
If we subtract 3126 from 3306, 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.

Going ahead to step 9:
The number 521 fits into 1800 3 times, leaving a remainder of 237.
The next digit of our result is 3. 
Result so far: 135036.3
If we subtract 1563 from 1800, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 10:
521 can be fit into 2370 4 times, resulting in a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 135036.34
If we subtract 2084 from 2370, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 11:
521 can be fit into 2860 5 times, resulting in a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 135036.345
Deduct 2605 from 2860 and we're left 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.

Step 12:
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: 135036.3454
Subtracting 2084 from 2550 leaves us 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.

Advancing to step 13:
521 can be fit into 4660 8 times, resulting in a remainder of 492.
The number 8 becomes the next digit in our result. 
Result so far: 135036.34548
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.

Advancing to step 14:
The number 521 fits into 4920 9 times, leaving a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 135036.345489
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.

Moving on to step 15:
521 goes into 2310 4 times with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 135036.3454894
Deduct 2084 from 2310 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 16:
521 can be fit into 2260 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 135036.34548944
Subtract 2084 from 2260 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 135036.34548944 with a balance of 1.76e-07.
