We look at the division of 180903 by 57 
We're looking to find how many times 57 goes into 180903.

Step 1:
57 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 57

On to step 2:
57 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 57

Step 3:
When dividing 180 by 57, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 171 away from 180, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 57

Let's proceed to step 4:
The number 57 fits into 99 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 57 from 99 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 57

Let's proceed to step 5:
57 can be fit into 420 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Deduct 399 from 420 and we're left with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 57

Going ahead to step 6:
57 goes into 213 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3173.0
Deduct 171 from 213 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.

Moving on to step 7:
57 goes into 420 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 3173.7
If we take 399 away from 420, we end up with 21.
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 8:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 3173.73
If we take 171 away from 210, we end up 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.

Advancing to step 9:
When dividing 390 by 57, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 3173.736
The remainder is 48 after subtracting 342 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
57 can be fit into 480 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3173.7368
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
When dividing 240 by 57, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 3173.73684
The remainder is 12 after subtracting 228 from 240.
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 12:
120 divided by 57 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3173.736842
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
57 can be fit into 60 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 3173.7368421
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
When dividing 30 by 57, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3173.7368421
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3173.7368421, with a leftover of 3e-08.
