We look at the division of 453381 by 51 
We want to figure out the number of times 453381 can be divided by 51.

Advancing to step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 51

On to step 2:
51 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 51

Going ahead to step 3:
The number 51 fits into 453 8 times, leaving a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 408 from 453 to get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 51

Step 4:
453 divided by 51 is 8 with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 45 after subtracting 408 from 453.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 51

Going ahead to step 5:
51 goes into 458 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 888.0
Subtracting 408 from 458 leaves us with 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 51

Going ahead to step 6:
501 divided by 51 is 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 8889.0
Deduct 459 from 501 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8889.8
If we take 408 away from 420, we end up 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.

Going ahead to step 8:
120 divided by 51 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 8889.82
If we take 102 away from 120, we end up 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.

Going ahead to step 9:
The number 51 fits into 180 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 8889.823
The remainder is 27 after subtracting 153 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
When dividing 270 by 51, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8889.8235
Deduct 255 from 270 and we're left 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.

Going ahead to step 11:
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: 8889.82352
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
51 goes into 480 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 8889.823529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
When dividing 210 by 51, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 8889.8235294
If we subtract 204 from 210, we 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.

Step 14:
If we divide 60 by 51, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 8889.82352941
If we take 51 away from 60, we end up 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.

After the division, we end up with 8889.82352941 and a remainder of 9e-09.
