We look at the division of 691651 by 15 
We want to figure out the number of times 691651 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 15

Moving on to step 2:
If we divide 69 by 15, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 60 away from 69, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 15

Advancing to step 3:
The number 15 fits into 91 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 90 from 91 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 15

Let's proceed to step 4:
When dividing 16 by 15, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtract 15 from 16 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 15

Advancing to step 5:
15 divided by 15 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4611.0
If we subtract 15 from 15, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 15

On to step 6:
The number 15 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 46110.0
Deduct 0 from 1 and we're left 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.

Going ahead to step 7:
If we divide 10 by 15, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 46110.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 46110.06
Deduct 90 from 100 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.

Moving on to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 46110.066
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 46110.066 and a remainder of 0.001.
