We're dividing 610291 by 12 
We want to figure out the number of times 610291 can be divided by 12.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

Advancing to step 2:
12 goes into 61 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 60 from 61 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

On to step 3:
10 divided by 12 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 10 to get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 12

Advancing to step 4:
The number 12 fits into 102 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 508.0
Deduct 96 from 102 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 12

Advancing to step 5:
The number 12 fits into 69 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 5085.0
If we take 60 away from 69, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

Moving on to step 6:
The number 12 fits into 91 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 50857.0
Subtracting 84 from 91 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
12 goes into 70 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 50857.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 50857.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 50857.583
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 50857.5833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 50857.5833 with a remaining 4e-05.
