We divide 664573 by 57
Let's see how many times 57 fits into 664573.

Going ahead to step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 57

On to step 2:
If we divide 66 by 57, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 57 from 66 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 57

On to step 3:
57 can be fit into 94 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 57 away from 94, we end up with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 57

Let's proceed to step 4:
If we divide 375 by 57, we get 6 and a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 342 from 375 and we're left with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 57

Step 5:
When dividing 337 by 57, we get 5 with a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
If we take 285 away from 337, we end up with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 57

Advancing to step 6:
57 goes into 523 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 11659.0
If we subtract 513 from 523, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 57 fits into 100 1 times, leaving a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 11659.1
The remainder is 43 after subtracting 57 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
57 can be fit into 430 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 11659.17
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
If we divide 310 by 57, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11659.175
Subtract 285 from 310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
The number 57 fits into 250 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 11659.1754
If we take 228 away from 250, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
The number 57 fits into 220 3 times, leaving a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 11659.17543
If we subtract 171 from 220, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
57 goes into 490 8 times with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 11659.175438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
If we divide 340 by 57, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11659.1754385
If we take 285 away from 340, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
57 can be fit into 550 9 times, resulting in a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 11659.17543859
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 11659.17543859, with a leftover of 3.7e-08.
