Let's divide 204172 by 57
Our goal is to divide 204172 by 57.

Advancing to step 1:
57 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 57

Step 2:
20 divided by 57 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 57

Advancing to step 3:
204 divided by 57 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
If we take 171 away from 204, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 57

On to step 4:
When dividing 331 by 57, we get 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 285 away from 331, we end up with 46.
Append the next digit (7) from the dividend to 46 and continue with: 467 / 57

Moving on to step 5:
If we divide 467 by 57, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 358.0
The remainder is 11 after subtracting 456 from 467.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 57

Advancing to step 6:
If we divide 112 by 57, we get 1 and a remainder of 55.
The next digit of our result is 1. 
Result so far: 3581.0
If we subtract 57 from 112, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
57 goes into 550 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 3581.9
Deduct 513 from 550 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
370 divided by 57 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 3581.96
If we subtract 342 from 370, we 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 9:
The number 57 fits into 280 4 times, leaving a remainder of 52.
The next digit of our result is 4. 
Result so far: 3581.964
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
57 goes into 520 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 3581.9649
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.

Let's proceed to step 11:
The number 57 fits into 70 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 3581.96491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
57 goes into 130 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 3581.964912
The remainder is 16 after subtracting 114 from 130.
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 13:
The number 57 fits into 160 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 3581.9649122
Subtract 114 from 160 to get 46.
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 3581.9649122 with a remainder of 4.6e-07.
