Let's divide 666369 by 57
We want to figure out the number of times 666369 can be divided by 57.

Step 1:
57 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 57

Advancing to step 2:
The number 57 fits into 66 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 57 from 66 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 57

Step 3:
The number 57 fits into 96 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 39 after subtracting 57 from 96.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 57

Step 4:
When dividing 393 by 57, we get 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 342 from 393 leaves us with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 57

Advancing to step 5:
If we divide 516 by 57, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1169.0
If we subtract 513 from 516, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 57

Advancing to step 6:
When dividing 39 by 57, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 11690.0
If we subtract 0 from 39, we get 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 7:
The number 57 fits into 390 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 11690.6
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
480 divided by 57 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 11690.68
If we subtract 456 from 480, we get 24.
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 9:
If we divide 240 by 57, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11690.684
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.

On to step 10:
When dividing 120 by 57, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 11690.6842
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
If we divide 60 by 57, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 11690.68421
Subtract 57 from 60 to get 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 12:
The number 57 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11690.68421
If we take 0 away from 30, we end up 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.

Moving on to step 13:
300 divided by 57 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11690.6842105
If we take 285 away from 300, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 11690.68421052
If we subtract 114 from 150, we 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.

Our division results in 11690.68421052 with a remaining 3.6e-08.
