We divide 686242 by 57
We want to figure out the number of times 686242 can be divided by 57.

On to step 1:
57 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 57

Going ahead to step 2:
If we divide 68 by 57, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 68 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 57

Let's proceed to step 3:
When dividing 116 by 57, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 114 from 116 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 57

On to step 4:
57 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 22 to get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 57

Advancing to step 5:
When dividing 224 by 57, we get 3 with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 1203.0
If we take 171 away from 224, we end up with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 57

On to step 6:
57 goes into 532 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 12039.0
Subtract 513 from 532 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 57 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 12039.3
Deduct 171 from 190 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
The number 57 fits into 190 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 12039.33
If we take 171 away from 190, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 12039.33 with a remaining 0.019.
