691561 ÷ 12 
We want to divide 691561 by 12.

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.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 12

Step 2:
12 can be fit into 69 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 60 from 69 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

Step 3:
91 divided by 12 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 57.0
The remainder is 7 after subtracting 84 from 91.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

Advancing to step 4:
When dividing 75 by 12, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 576.0
The remainder is 3 after subtracting 72 from 75.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 12

Going ahead to step 5:
36 divided by 12 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 5763.0
Subtract 36 from 36 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

Let's proceed to step 6:
12 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 57630.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 12 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 57630.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
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: 57630.08
If we subtract 96 from 100, 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.
Put 3 as the next digit of the answer. 
Result so far: 57630.083
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:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 57630.0833
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.

The final outcome is 57630.0833, with a leftover of 4e-05.
