84010318 ÷ 453 
Our goal is to divide 84010318 by 453.

Moving on to step 1:
When dividing 8 by 453, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 453

On to step 2:
453 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.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 453

Advancing to step 3:
840 divided by 453 is 1 with a remainder of 387.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 453 from 840, we get 387.
Include the next digit (1) from the dividend after 387, then repeat: 3871 / 453

Step 4:
If we divide 3871 by 453, we get 8 and a remainder of 247.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 3624 from 3871 to get 247.
Grab the next digit (0) from the dividend, add it to 247, then carry on: 2470 / 453

Advancing to step 5:
The number 453 fits into 2470 5 times, leaving a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 185.0
If we take 2265 away from 2470, we end up with 205.
Bring next digit (3) of the dividend behind the 205 and repeat the process: 2053 / 453

Moving on to step 6:
453 goes into 2053 4 times with a remainder of 241.
Use 4 as the next digit of our solution. 
Result so far: 1854.0
If we subtract 1812 from 2053, we get 241.
Bring next digit (1) of the dividend behind the 241 and repeat the process: 2411 / 453

Moving on to step 7:
The number 453 fits into 2411 5 times, leaving a remainder of 146.
Put 5 as the next digit of the answer. 
Result so far: 18545.0
The remainder is 146 after subtracting 2265 from 2411.
Fetch the next digit (8) from the dividend, attach it to 146 and continue: 1468 / 453

Let's proceed to step 8:
When dividing 1468 by 453, we get 3 with a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 185453.0
Subtracting 1359 from 1468 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
453 can be fit into 1090 2 times, resulting in a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 185453.2
The remainder is 184 after subtracting 906 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
453 can be fit into 1840 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 185453.24
If we subtract 1812 from 1840, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
When dividing 280 by 453, we get 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 185453.24
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
2800 divided by 453 is 6 with a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 185453.2406
The remainder is 82 after subtracting 2718 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
453 can be fit into 820 1 times, resulting in a remainder of 367.
Put 1 as the next digit of the answer. 
Result so far: 185453.24061
If we take 453 away from 820, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 14:
The number 453 fits into 3670 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 185453.240618
Subtracting 3624 from 3670 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
453 can be fit into 460 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 185453.2406181
Subtracting 453 from 460 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 16:
453 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 185453.2406181
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 185453.2406181, with a leftover of 7e-08.
