We're dividing 81358 by 66 
We want to figure out the number of times 81358 can be divided by 66.

Moving on to 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
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 66

On to step 2:
The number 66 fits into 81 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 66 from 81, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 66

Let's proceed to step 3:
153 divided by 66 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 21 after subtracting 132 from 153.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 66

Moving on to step 4:
The number 66 fits into 215 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtract 198 from 215 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 66

Let's proceed to step 5:
66 can be fit into 178 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
The remainder is 46 after subtracting 132 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 6:
66 goes into 460 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1232.6
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.

Step 7:
640 divided by 66 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1232.69
If we subtract 594 from 640, we 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.

Advancing to step 8:
When dividing 460 by 66, we get 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1232.696
Subtract 396 from 460 to 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.

Step 9:
When dividing 640 by 66, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1232.6969
Deduct 594 from 640 and we're left 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.

Going ahead to step 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 1232.69696
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 11:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1232.696969
Deduct 594 from 640 and we're left 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 12:
When dividing 460 by 66, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1232.6969696
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.

Step 13:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1232.69696969
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.

After the division, we end up with 1232.69696969 and a remainder of 4.6e-08.
