We look at the division of 51434399 by 574 
We want to figure out the number of times 51434399 can be divided by 574.

Advancing to step 1:
574 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 574

On to step 2:
574 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 574

On to step 3:
If we divide 514 by 574, we get 0 and a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 514 after subtracting 0 from 514.
Bring next digit (3) of the dividend behind the 514 and repeat the process: 5143 / 574

Let's proceed to step 4:
574 goes into 5143 8 times with a remainder of 551.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 551 after subtracting 4592 from 5143.
Grab the next digit (4) from the dividend, add it to 551, then carry on: 5514 / 574

Going ahead to step 5:
When dividing 5514 by 574, we get 9 with a remainder of 348.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 348 after subtracting 5166 from 5514.
Take the next digit (3) from the dividend and append it to 348, then repeat: 3483 / 574

On to step 6:
574 goes into 3483 6 times with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 896.0
Subtract 3444 from 3483 to get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 574

Going ahead to step 7:
If we divide 399 by 574, we get 0 and a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 8960.0
Subtract 0 from 399 to get 399.
Include the next digit (9) from the dividend after 399, then repeat: 3999 / 574

Moving on to step 8:
574 goes into 3999 6 times with a remainder of 555.
Write down 6 as next digit of the result. 
Result so far: 89606.0
If we subtract 3444 from 3999, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 9:
574 goes into 5550 9 times with a remainder of 384.
The next digit of our result is 9. 
Result so far: 89606.9
Deduct 5166 from 5550 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 10:
3840 divided by 574 is 6 with a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 89606.96
Subtract 3444 from 3840 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
574 can be fit into 3960 6 times, resulting in a remainder of 516.
Write down 6 as next digit of the result. 
Result so far: 89606.966
Subtract 3444 from 3960 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

In conclusion, the division gives 89606.966 with a balance of 0.0516.
