We look at the division of 455173 by 57 
Our goal is to divide 455173 by 57.

Moving on to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 57

Moving on to step 2:
57 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 57

Let's proceed to step 3:
57 can be fit into 455 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 399 from 455 and we're left with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 57

On to step 4:
When dividing 561 by 57, we get 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 513 away from 561, we end up with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 57

On to step 5:
57 goes into 487 8 times with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 798.0
Subtract 456 from 487 to get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 57

Let's proceed to step 6:
The number 57 fits into 313 5 times, leaving a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 7985.0
Subtract 285 from 313 to 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.

Moving on to step 7:
280 divided by 57 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 7985.4
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
When dividing 520 by 57, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 7985.49
Deduct 513 from 520 and we're left 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.

On to step 9:
70 divided by 57 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 7985.491
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 57, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 7985.4912
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 57, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 7985.49122
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 7985.49122 with a remainder of 4.6e-05.
