541691 divided by 12 
We want to figure out the number of times 541691 can be divided by 12.

On to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 12

Advancing to step 2:
12 can be fit into 54 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 48 from 54, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

On to step 3:
When dividing 61 by 12, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 60 from 61 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 12

Advancing to step 4:
When dividing 16 by 12, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Deduct 12 from 16 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

On to step 5:
The number 12 fits into 49 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4514.0
The remainder is 1 after subtracting 48 from 49.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 12

Let's proceed to step 6:
When dividing 11 by 12, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 45140.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 45140.9
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 45140.91
Subtracting 12 from 20 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.

Advancing to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 45140.916
If we take 72 away from 80, 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.

Advancing to step 10:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 45140.9166
If we subtract 72 from 80, 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.

The final outcome is 45140.9166, with a leftover of 8e-05.
