51233134 ÷ 521 
We want to divide 51233134 by 521.

Going ahead to step 1:
5 divided by 521 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 521

Step 2:
51 divided by 521 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 521

Going ahead to step 3:
When dividing 512 by 521, we get 0 with a remainder of 512.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 512, we end up with 512.
Include the next digit (3) from the dividend after 512, then repeat: 5123 / 521

Let's proceed to step 4:
If we divide 5123 by 521, we get 9 and a remainder of 434.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 4689 away from 5123, we end up with 434.
Grab the next digit (3) from the dividend, add it to 434, then carry on: 4343 / 521

Step 5:
If we divide 4343 by 521, we get 8 and a remainder of 175.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 4168 from 4343 and we're left with 175.
Fetch the next digit (1) from the dividend, attach it to 175 and continue: 1751 / 521

On to step 6:
521 goes into 1751 3 times with a remainder of 188.
Use 3 as the next digit of our solution. 
Result so far: 983.0
If we take 1563 away from 1751, we end up with 188.
Grab the next digit (3) from the dividend, add it to 188, then carry on: 1883 / 521

Step 7:
521 can be fit into 1883 3 times, resulting in a remainder of 320.
Put 3 as the next digit of the answer. 
Result so far: 9833.0
Subtracting 1563 from 1883 leaves us with 320.
Include the next digit (4) from the dividend after 320, then repeat: 3204 / 521

Let's proceed to step 8:
521 goes into 3204 6 times with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 98336.0
Subtracting 3126 from 3204 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
780 divided by 521 is 1 with a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 98336.1
Deduct 521 from 780 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 10:
521 can be fit into 2590 4 times, resulting in a remainder of 506.
The next digit of our result is 4. 
Result so far: 98336.14
If we take 2084 away from 2590, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 11:
521 can be fit into 5060 9 times, resulting in a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 98336.149
Subtracting 4689 from 5060 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 12:
When dividing 3710 by 521, we get 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 98336.1497
Subtracting 3647 from 3710 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
When dividing 630 by 521, we get 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 98336.14971
Deduct 521 from 630 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 14:
1090 divided by 521 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 98336.149712
Deduct 1042 from 1090 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
480 divided by 521 is 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 98336.149712
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
The number 521 fits into 4800 9 times, leaving a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 98336.14971209
The remainder is 111 after subtracting 4689 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

In conclusion, the division gives 98336.14971209 with a balance of 1.11e-07.
