We look at the division of 166590 by 57 
We want to figure out the number of times 166590 can be divided by 57.

Moving on to step 1:
57 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 57

Going ahead to step 2:
16 divided by 57 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 57

Step 3:
If we divide 166 by 57, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 52 after subtracting 114 from 166.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 57

Moving on to step 4:
57 goes into 525 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 513 from 525 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 57

Step 5:
129 divided by 57 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 292.0
The remainder is 15 after subtracting 114 from 129.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 57

Going ahead to step 6:
150 divided by 57 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2922.0
Subtract 114 from 150 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
360 divided by 57 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 2922.6
If we take 342 away from 360, 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.

Step 8:
57 goes into 180 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 2922.63
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
57 goes into 90 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 2922.631
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2922.6315
Deduct 285 from 330 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
57 can be fit into 450 7 times, resulting in a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 2922.63157
Deduct 399 from 450 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
If we divide 510 by 57, we get 8 and a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 2922.631578
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
The number 57 fits into 540 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 2922.6315789
Subtract 513 from 540 to get 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 14:
The number 57 fits into 270 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 2922.63157894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 2922.63157894, and the remainder is 4.2e-08.
