668837 ÷ 66 
Let's see how many times 66 fits into 668837.

Going ahead to step 1:
6 divided by 66 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 66

Going ahead to step 2:
If we divide 66 by 66, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 66 away from 66, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 66

Let's proceed to step 3:
66 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 66

Let's proceed to step 4:
88 divided by 66 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 101.0
If we take 66 away from 88, we end up with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 66

Moving on to step 5:
If we divide 223 by 66, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
The remainder is 25 after subtracting 198 from 223.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 66

On to step 6:
66 goes into 257 3 times with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 10133.0
If we take 198 away from 257, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
If we divide 590 by 66, we get 8 and a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 10133.8
If we subtract 528 from 590, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
66 goes into 620 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 10133.89
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
66 goes into 260 3 times with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 10133.893
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 10133.8939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 66, we get 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 10133.89393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 10133.893939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
66 goes into 260 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 10133.8939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 10133.89393939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 10133.89393939, and the remainder is 2.6e-08.
