We're dividing 52308842 by 12 
We want to figure out the number of times 52308842 can be divided by 12.

Going ahead to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 12

Going ahead to step 2:
If we divide 52 by 12, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 48 from 52 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

On to step 3:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 36 from 43 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 12

Going ahead to step 4:
12 goes into 70 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
If we subtract 60 from 70, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

On to step 5:
The number 12 fits into 108 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4359.0
Deduct 108 from 108 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 12

Going ahead to step 6:
12 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 43590.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 12

Advancing to step 7:
If we divide 84 by 12, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 435907.0
Deduct 84 from 84 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 12

On to step 8:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 4359070.0
Subtract 0 from 2 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.

On to step 9:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 4359070.1
The remainder is 8 after subtracting 12 from 20.
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.
Write down 6 as next digit of the result. 
Result so far: 4359070.16
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.

Going ahead to step 11:
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: 4359070.166
Deduct 72 from 80 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 result is 4359070.166 with a remainder of 0.0008.
