We look at the division of 61542848 by 12 
Let's see how many times 12 fits into 61542848.

Advancing to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Moving on to step 2:
12 can be fit into 61 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 60 from 61 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Moving on to step 3:
15 divided by 12 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 3 after subtracting 12 from 15.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

On to step 4:
When dividing 34 by 12, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 512.0
Subtract 24 from 34 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Going ahead to step 5:
If we divide 102 by 12, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 5128.0
Subtract 96 from 102 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Step 6:
When dividing 68 by 12, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 51285.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

On to step 7:
The number 12 fits into 84 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 512857.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Step 8:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 5128570.0
If we take 0 away from 8, 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.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5128570.6
Subtract 72 from 80 to 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.

Moving on to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5128570.66
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 5128570.66, with a leftover of 0.008.
