54257931 ÷ 434 
Our goal is to divide 54257931 by 434.

Advancing to step 1:
5 divided by 434 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 434

Moving on to step 2:
434 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 434

Let's proceed to step 3:
434 goes into 542 1 times with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 434 from 542, we get 108.
Grab the next digit (5) from the dividend, add it to 108, then carry on: 1085 / 434

Let's proceed to step 4:
434 goes into 1085 2 times with a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 868 from 1085 to get 217.
Take the next digit (7) from the dividend and append it to 217, then repeat: 2177 / 434

Moving on to step 5:
If we divide 2177 by 434, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 7 after subtracting 2170 from 2177.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 434

Advancing to step 6:
434 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 1250.0
If we take 0 away from 79, we end up with 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 434

Moving on to step 7:
When dividing 793 by 434, we get 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 12501.0
Deduct 434 from 793 and we're left with 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 434

Moving on to step 8:
434 can be fit into 3591 8 times, resulting in a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 125018.0
The remainder is 119 after subtracting 3472 from 3591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 9:
434 goes into 1190 2 times with a remainder of 322.
The next digit of our result is 2. 
Result so far: 125018.2
If we subtract 868 from 1190, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 10:
3220 divided by 434 is 7 with a remainder of 182.
Record the quotient 7 as the next digit in the result. 
Result so far: 125018.27
If we take 3038 away from 3220, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
When dividing 1820 by 434, we get 4 with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 125018.274
If we subtract 1736 from 1820, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
The number 434 fits into 840 1 times, leaving a remainder of 406.
The next digit of our result is 1. 
Result so far: 125018.2741
Subtract 434 from 840 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 13:
When dividing 4060 by 434, we get 9 with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 125018.27419
Deduct 3906 from 4060 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 14:
The number 434 fits into 1540 3 times, leaving a remainder of 238.
Put 3 as the next digit of the answer. 
Result so far: 125018.274193
The remainder is 238 after subtracting 1302 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 15:
If we divide 2380 by 434, we get 5 and a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 125018.2741935
Subtracting 2170 from 2380 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 16:
434 goes into 2100 4 times with a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 125018.27419354
If we take 1736 away from 2100, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The quotient of the division is 125018.27419354, and the remainder is 3.64e-07.
