Let's divide 66486 by 57
We want to divide 66486 by 57.

Step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
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

Going ahead 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
If we take 57 away from 66, we end up with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 57

Moving on to step 3:
94 divided by 57 is 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 37 after subtracting 57 from 94.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 57

Moving on to step 4:
378 divided by 57 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 342 from 378, we get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 57

Moving on to step 5:
The number 57 fits into 366 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1166.0
The remainder is 24 after subtracting 342 from 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 6:
57 goes into 240 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1166.4
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 57 fits into 120 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1166.42
Subtract 114 from 120 to 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.

Advancing to step 8:
60 divided by 57 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1166.421
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
57 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1166.421
Subtracting 0 from 30 leaves us 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.

Advancing to step 10:
The number 57 fits into 300 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1166.42105
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.

Going ahead to step 11:
57 goes into 150 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1166.421052
If we take 114 away from 150, we end up with 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 12:
57 goes into 360 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 1166.4210526
Subtracting 342 from 360 leaves us 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.

On to step 13:
57 goes into 180 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1166.42105263
If we subtract 171 from 180, we 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.

The quotient of the division is 1166.42105263, and the remainder is 9e-09.
