We're dividing 689998 by 12 
Let's see how many times 12 fits into 689998.

Let's proceed to step 1:
The number 12 fits into 6 0 times, leaving 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 (8) from the dividend, attach it to 6 and continue: 68 / 12

Going ahead to step 2:
12 goes into 68 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 8 after subtracting 60 from 68.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

Let's proceed to step 3:
When dividing 89 by 12, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 5 after subtracting 84 from 89.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

Advancing to step 4:
59 divided by 12 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 574.0
If we subtract 48 from 59, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 12

Going ahead to step 5:
If we divide 119 by 12, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 5749.0
If we take 108 away from 119, we end up with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Let's proceed to step 6:
When dividing 118 by 12, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 57499.0
Deduct 108 from 118 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 57499.8
If we take 96 away from 100, we end up 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.

Going ahead to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 57499.83
If we subtract 36 from 40, we 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.

Going ahead to step 9:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 57499.833
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.

The quotient of the division is 57499.833, and the remainder is 0.0004.
