84130270 ÷ 455 
Our goal is to divide 84130270 by 455.

Moving on to step 1:
455 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 455

Going ahead to step 2:
455 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 455

On to step 3:
If we divide 841 by 455, we get 1 and a remainder of 386.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 386 after subtracting 455 from 841.
Grab the next digit (3) from the dividend, add it to 386, then carry on: 3863 / 455

Moving on to step 4:
3863 divided by 455 is 8 with a remainder of 223.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 223 after subtracting 3640 from 3863.
Take the next digit (0) from the dividend and append it to 223, then repeat: 2230 / 455

On to step 5:
The number 455 fits into 2230 4 times, leaving a remainder of 410.
Put 4 as the next digit of the answer. 
Result so far: 184.0
The remainder is 410 after subtracting 1820 from 2230.
Include the next digit (2) from the dividend after 410, then repeat: 4102 / 455

On to step 6:
The number 455 fits into 4102 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1849.0
Deduct 4095 from 4102 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 455

Advancing to step 7:
If we divide 77 by 455, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 18490.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 455

Step 8:
455 can be fit into 770 1 times, resulting in a remainder of 315.
Write down 1 as next digit of the result. 
Result so far: 184901.0
Subtract 455 from 770 to 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.

Moving on to step 9:
If we divide 3150 by 455, we get 6 and a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 184901.6
If we subtract 2730 from 3150, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 10:
If we divide 4200 by 455, we get 9 and a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 184901.69
Subtract 4095 from 4200 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
If we divide 1050 by 455, we get 2 and a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 184901.692
If we take 910 away from 1050, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
455 goes into 1400 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 184901.6923
Deduct 1365 from 1400 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
455 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 184901.6923
If we subtract 0 from 350, we get 350.
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 14:
The number 455 fits into 3500 7 times, leaving a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 184901.692307
Subtract 3185 from 3500 to 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.

Moving on to step 15:
The number 455 fits into 3150 6 times, leaving a remainder of 420.
Use 6 as the next digit of our solution. 
Result so far: 184901.6923076
The remainder is 420 after subtracting 2730 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 16:
When dividing 4200 by 455, we get 9 with a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 184901.69230769
The remainder is 105 after subtracting 4095 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 184901.69230769 with a balance of 1.05e-07.
