84432359 ÷ 66 
We want to figure out the number of times 84432359 can be divided by 66.

Step 1:
66 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 66

Step 2:
The number 66 fits into 84 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 66 away from 84, we end up with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 66

Step 3:
66 goes into 184 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 132 from 184 leaves us with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 66

Moving on to step 4:
When dividing 523 by 66, we get 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Deduct 462 from 523 and we're left with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 66

Moving on to step 5:
The number 66 fits into 612 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1279.0
If we subtract 594 from 612, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 66

On to step 6:
When dividing 183 by 66, we get 2 with a remainder of 51.
The next digit of our result is 2. 
Result so far: 12792.0
Subtracting 132 from 183 leaves us with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 66

Advancing to step 7:
66 can be fit into 515 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 127927.0
Deduct 462 from 515 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 66

Moving on to step 8:
If we divide 539 by 66, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 1279278.0
The remainder is 11 after subtracting 528 from 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 66, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1279278.1
Subtract 66 from 110 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
66 goes into 440 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 1279278.16
Subtract 396 from 440 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
The number 66 fits into 440 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1279278.166
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 1279278.166, and the remainder is 0.0044.
