51287831 ÷ 434 
We're looking to find how many times 434 goes into 51287831.

Advancing to step 1:
The number 434 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 434

Step 2:
434 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 434

Advancing to step 3:
434 can be fit into 512 1 times, resulting in a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 434 from 512 leaves us with 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 434

Let's proceed to step 4:
434 goes into 788 1 times with a remainder of 354.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 354 after subtracting 434 from 788.
Include the next digit (7) from the dividend after 354, then repeat: 3547 / 434

Advancing to step 5:
If we divide 3547 by 434, we get 8 and a remainder of 75.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 3472 from 3547, we get 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 434

Going ahead to step 6:
The number 434 fits into 758 1 times, leaving a remainder of 324.
Use 1 as the next digit of our solution. 
Result so far: 1181.0
Deduct 434 from 758 and we're left with 324.
Include the next digit (3) from the dividend after 324, then repeat: 3243 / 434

Step 7:
434 can be fit into 3243 7 times, resulting in a remainder of 205.
Write down 7 as next digit of the result. 
Result so far: 11817.0
If we subtract 3038 from 3243, we get 205.
Grab the next digit (1) from the dividend, add it to 205, then carry on: 2051 / 434

Advancing to step 8:
If we divide 2051 by 434, we get 4 and a remainder of 315.
Put 4 as the next digit of the answer. 
Result so far: 118174.0
If we subtract 1736 from 2051, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
434 goes into 3150 7 times with a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 118174.7
If we subtract 3038 from 3150, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 10:
The number 434 fits into 1120 2 times, leaving a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 118174.72
The remainder is 252 after subtracting 868 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
When dividing 2520 by 434, we get 5 with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 118174.725
The remainder is 350 after subtracting 2170 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
When dividing 3500 by 434, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 118174.7258
The remainder is 28 after subtracting 3472 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
When dividing 280 by 434, we get 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 118174.7258
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
2800 divided by 434 is 6 with a remainder of 196.
The next digit of our result is 6. 
Result so far: 118174.725806
Subtracting 2604 from 2800 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 15:
When dividing 1960 by 434, we get 4 with a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 118174.7258064
The remainder is 224 after subtracting 1736 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 16:
434 goes into 2240 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 118174.72580645
If we subtract 2170 from 2240, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 118174.72580645 with a balance of 7e-08.
