429488 ÷ 66 
Let's see how many times 66 fits into 429488.

On to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 66

Advancing to step 2:
66 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 66

Moving on to step 3:
If we divide 429 by 66, we get 6 and a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 396 from 429 and we're left with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 66

Step 4:
If we divide 334 by 66, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 330 from 334 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 66

On to step 5:
66 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 650.0
The remainder is 48 after subtracting 0 from 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 66

Step 6:
488 divided by 66 is 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 6507.0
Subtracting 462 from 488 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.

Going ahead to step 7:
260 divided by 66 is 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 6507.3
Subtract 198 from 260 to 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 can be fit into 620 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 6507.39
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 6507.393
If we take 198 away from 260, we end up 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.

Going ahead to step 10:
If we divide 620 by 66, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 6507.3939
Subtract 594 from 620 to 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.

Advancing to step 11:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 6507.39393
If we subtract 198 from 260, 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.

Going ahead to step 12:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 6507.393939
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.

Going ahead to step 13:
66 goes into 260 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 6507.3939393
If we take 198 away from 260, we end up 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.

Let's proceed to step 14:
If we divide 620 by 66, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 6507.39393939
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.

The final outcome is 6507.39393939, with a leftover of 2.6e-08.
