619751 divided by 12 
Let's see how many times 12 fits into 619751.

On to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

On to step 2:
61 divided by 12 is 5 with 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.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

Let's proceed to step 3:
19 divided by 12 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 12 from 19 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 12

Moving on to step 4:
When dividing 77 by 12, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 516.0
If we take 72 away from 77, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

On to step 5:
When dividing 55 by 12, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 5164.0
If we take 48 away from 55, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

Advancing to step 6:
If we divide 71 by 12, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 51645.0
Subtracting 60 from 71 leaves us 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:
110 divided by 12 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 51645.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 51645.91
Subtract 12 from 20 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.

Going ahead to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 51645.916
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:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 51645.9166
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.

The quotient of the division is 51645.9166, and the remainder is 8e-05.
