669154 ÷ 66 
We want to divide 669154 by 66.

Going ahead to step 1:
66 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 66

Step 2:
66 divided by 66 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 66 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 66

Going ahead to step 3:
If we divide 9 by 66, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 66

Moving on to step 4:
66 can be fit into 91 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 66 from 91 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 66

Going ahead to step 5:
When dividing 255 by 66, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
The remainder is 57 after subtracting 198 from 255.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 66

Going ahead to step 6:
The number 66 fits into 574 8 times, leaving a remainder of 46.
The next digit of our result is 8. 
Result so far: 10138.0
The remainder is 46 after subtracting 528 from 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
66 can be fit into 460 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 10138.6
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10138.69
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 10138.696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 10138.6969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
66 goes into 460 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 10138.69696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 10138.696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
460 divided by 66 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 10138.6969696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 10138.69696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 10138.69696969, with a leftover of 4.6e-08.
