We look at the division of 453402 by 51 
Let's see how many times 51 fits into 453402.

Advancing to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 51

Going ahead to step 2:
If we divide 45 by 51, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 51

On to step 3:
51 goes into 453 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 408 from 453, we get 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 51

Let's proceed to step 4:
If we divide 454 by 51, we get 8 and a remainder of 46.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 46 after subtracting 408 from 454.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 51

Moving on to step 5:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 889.0
Subtract 459 from 460 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 51

On to step 6:
The number 51 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 8890.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
If we divide 120 by 51, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 8890.2
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 51, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 8890.23
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8890.235
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 51 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 8890.2352
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
If we divide 480 by 51, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8890.23529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 8890.235294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 8890.2352941
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 8890.23529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 8890.23529411 with a remainder of 3.9e-08.
