We look at the division of 105443 by 66 
We're looking to find how many times 66 goes into 105443.

Going ahead to step 1:
66 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 66

Step 2:
If we divide 10 by 66, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 66

Let's proceed to step 3:
105 divided by 66 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 66 from 105, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 66

Let's proceed to step 4:
If we divide 394 by 66, we get 5 and a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 330 from 394, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 66

Going ahead to step 5:
644 divided by 66 is 9 with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 594 from 644 to get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 66

Moving on to step 6:
If we divide 503 by 66, we get 7 and a remainder of 41.
The next digit of our result is 7. 
Result so far: 1597.0
Subtracting 462 from 503 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 66 fits into 410 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1597.6
Subtract 396 from 410 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.

Let's proceed to step 8:
66 goes into 140 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1597.62
Deduct 132 from 140 and we're left 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.

Advancing to step 9:
If we divide 80 by 66, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1597.621
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.

Moving on to step 10:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1597.6212
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.

On to step 11:
66 goes into 80 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1597.62121
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.

On to step 12:
66 goes into 140 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1597.621212
Deduct 132 from 140 and we're left 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.

Step 13:
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: 1597.6212121
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.

Going ahead to step 14:
66 can be fit into 140 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 1597.62121212
Deduct 132 from 140 and we're left 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.

The final outcome is 1597.62121212, with a leftover of 8e-09.
