423926 ÷ 66 
We're looking to find how many times 66 goes into 423926.

Going ahead to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 66

Advancing to step 2:
When dividing 42 by 66, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 66

On to step 3:
The number 66 fits into 423 6 times, leaving a remainder of 27.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 27 after subtracting 396 from 423.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 66

Going ahead to step 4:
279 divided by 66 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 264 from 279 to get 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 66

Advancing to step 5:
66 can be fit into 152 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
If we subtract 132 from 152, we get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 66

Let's proceed to step 6:
When dividing 206 by 66, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 6423.0
If we subtract 198 from 206, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 66, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6423.1
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 66 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 6423.12
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6423.121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6423.1212
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 66 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6423.12121
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
The number 66 fits into 140 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 6423.121212
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 66 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 6423.1212121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
140 divided by 66 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 6423.12121212
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 6423.12121212 with a balance of 8e-09.
