29712357 ÷ 454 
We want to divide 29712357 by 454.

Let's proceed to step 1:
If we divide 2 by 454, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 454

Moving on to step 2:
The number 454 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 454

Moving on to step 3:
454 can be fit into 297 0 times, resulting in a remainder of 297.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 297, we get 297.
Grab the next digit (1) from the dividend, add it to 297, then carry on: 2971 / 454

Let's proceed to step 4:
If we divide 2971 by 454, we get 6 and a remainder of 247.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 2724 from 2971 and we're left with 247.
Include the next digit (2) from the dividend after 247, then repeat: 2472 / 454

Step 5:
454 can be fit into 2472 5 times, resulting in a remainder of 202.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 2270 from 2472 leaves us with 202.
Append the next digit (3) from the dividend to 202 and continue with: 2023 / 454

Advancing to step 6:
The number 454 fits into 2023 4 times, leaving a remainder of 207.
The next digit of our result is 4. 
Result so far: 654.0
Subtract 1816 from 2023 to get 207.
Fetch the next digit (5) from the dividend, attach it to 207 and continue: 2075 / 454

Going ahead to step 7:
If we divide 2075 by 454, we get 4 and a remainder of 259.
Put 4 as the next digit of the answer. 
Result so far: 6544.0
Subtract 1816 from 2075 to get 259.
Bring next digit (7) of the dividend behind the 259 and repeat the process: 2597 / 454

Advancing to step 8:
454 goes into 2597 5 times with a remainder of 327.
The next digit of our result is 5. 
Result so far: 65445.0
If we subtract 2270 from 2597, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
454 can be fit into 3270 7 times, resulting in a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 65445.7
Subtract 3178 from 3270 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
454 can be fit into 920 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 65445.72
The remainder is 12 after subtracting 908 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
If we divide 120 by 454, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 65445.72
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 454 fits into 1200 2 times, leaving a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 65445.7202
Deduct 908 from 1200 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 13:
If we divide 2920 by 454, we get 6 and a remainder of 196.
Put 6 as the next digit of the answer. 
Result so far: 65445.72026
Deduct 2724 from 2920 and we're left 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.

Step 14:
1960 divided by 454 is 4 with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 65445.720264
The remainder is 144 after subtracting 1816 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 15:
454 goes into 1440 3 times with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 65445.7202643
If we take 1362 away from 1440, we end up 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.

Let's proceed to step 16:
The number 454 fits into 780 1 times, leaving a remainder of 326.
The number 1 becomes the next digit in our result. 
Result so far: 65445.72026431
Subtracting 454 from 780 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

The final result is 65445.72026431 with a remainder of 3.26e-07.
