Let's divide 51270821 by 453
We're looking to find how many times 453 goes into 51270821.

Going ahead to step 1:
453 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 453

Going ahead to step 2:
When dividing 51 by 453, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 453

Moving on to step 3:
The number 453 fits into 512 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 453 from 512, we get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 453

Step 4:
The number 453 fits into 597 1 times, leaving a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 453 from 597 leaves us with 144.
Fetch the next digit (0) from the dividend, attach it to 144 and continue: 1440 / 453

Advancing to step 5:
453 can be fit into 1440 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we take 1359 away from 1440, we end up with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 453

Going ahead to step 6:
453 goes into 818 1 times with a remainder of 365.
Record the quotient 1 as the next digit in the result. 
Result so far: 1131.0
Subtracting 453 from 818 leaves us with 365.
Grab the next digit (2) from the dividend, add it to 365, then carry on: 3652 / 453

Going ahead to step 7:
If we divide 3652 by 453, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 11318.0
If we subtract 3624 from 3652, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 453

Advancing to step 8:
If we divide 281 by 453, we get 0 and a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 113180.0
The remainder is 281 after subtracting 0 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 9:
The number 453 fits into 2810 6 times, leaving a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 113180.6
Deduct 2718 from 2810 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
453 can be fit into 920 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 113180.62
If we subtract 906 from 920, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
453 can be fit into 140 0 times, resulting in a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 113180.62
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
If we divide 1400 by 453, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 113180.6203
If we subtract 1359 from 1400, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
453 goes into 410 0 times with a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 113180.6203
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 14:
453 can be fit into 4100 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 113180.620309
Subtracting 4077 from 4100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 15:
453 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 113180.620309
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 16:
2300 divided by 453 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 113180.62030905
Subtracting 2265 from 2300 leaves us 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.

The final result is 113180.62030905 with a remainder of 3.5e-08.
