Let's divide 66401161 by 99
We want to figure out the number of times 66401161 can be divided by 99.

Advancing to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 99

Moving on to step 2:
99 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 99

Step 3:
99 can be fit into 664 6 times, resulting in a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 594 from 664, we get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 99

Let's proceed to step 4:
If we divide 700 by 99, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we subtract 693 from 700, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 99

Let's proceed to step 5:
The number 99 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
If we subtract 0 from 71, we get 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 99

Advancing to step 6:
99 goes into 711 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 6707.0
The remainder is 18 after subtracting 693 from 711.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 99

On to step 7:
186 divided by 99 is 1 with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 67071.0
Deduct 99 from 186 and we're left with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 99

Let's proceed to step 8:
99 can be fit into 871 8 times, resulting in a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 670718.0
Subtracting 792 from 871 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
If we divide 790 by 99, we get 7 and a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 670718.7
Deduct 693 from 790 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 10:
970 divided by 99 is 9 with a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 670718.79
The remainder is 79 after subtracting 891 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
If we divide 790 by 99, we get 7 and a remainder of 97.
The next digit of our result is 7. 
Result so far: 670718.797
If we take 693 away from 790, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 12:
If we divide 970 by 99, we get 9 and a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 670718.7979
Subtracting 891 from 970 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
99 can be fit into 790 7 times, resulting in a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 670718.79797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 14:
99 can be fit into 970 9 times, resulting in a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 670718.797979
The remainder is 79 after subtracting 891 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 15:
When dividing 790 by 99, we get 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 670718.7979797
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 16:
The number 99 fits into 970 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 670718.79797979
Deduct 891 from 970 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 670718.79797979, and the remainder is 7.9e-08.
