We're dividing 68543668 by 434 
Our goal is to divide 68543668 by 434.

On to step 1:
When dividing 6 by 434, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 434

Going ahead to step 2:
When dividing 68 by 434, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 434

On to step 3:
434 can be fit into 685 1 times, resulting in a remainder of 251.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 434 from 685 and we're left with 251.
Append the next digit (4) from the dividend to 251 and continue with: 2514 / 434

Step 4:
434 goes into 2514 5 times with a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 344 after subtracting 2170 from 2514.
Bring next digit (3) of the dividend behind the 344 and repeat the process: 3443 / 434

Advancing to step 5:
434 can be fit into 3443 7 times, resulting in a remainder of 405.
The next digit of our result is 7. 
Result so far: 157.0
If we subtract 3038 from 3443, we get 405.
Bring next digit (6) of the dividend behind the 405 and repeat the process: 4056 / 434

Let's proceed to step 6:
434 can be fit into 4056 9 times, resulting in a remainder of 150.
Put 9 as the next digit of the answer. 
Result so far: 1579.0
Subtracting 3906 from 4056 leaves us with 150.
Take the next digit (6) from the dividend and append it to 150, then repeat: 1506 / 434

Advancing to step 7:
434 goes into 1506 3 times with a remainder of 204.
Record the quotient 3 as the next digit in the result. 
Result so far: 15793.0
Deduct 1302 from 1506 and we're left with 204.
Fetch the next digit (8) from the dividend, attach it to 204 and continue: 2048 / 434

Advancing to step 8:
If we divide 2048 by 434, we get 4 and a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 157934.0
If we take 1736 away from 2048, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 9:
434 can be fit into 3120 7 times, resulting in a remainder of 82.
The next digit of our result is 7. 
Result so far: 157934.7
Subtracting 3038 from 3120 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
820 divided by 434 is 1 with a remainder of 386.
Put 1 as the next digit of the answer. 
Result so far: 157934.71
Deduct 434 from 820 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 11:
434 can be fit into 3860 8 times, resulting in a remainder of 388.
The next digit of our result is 8. 
Result so far: 157934.718
Subtracting 3472 from 3860 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
434 goes into 3880 8 times with a remainder of 408.
Write down 8 as next digit of the result. 
Result so far: 157934.7188
Subtracting 3472 from 3880 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

In conclusion, the division gives 157934.7188 with a balance of 0.00408.
