769166 ÷ 15 
Our goal is to divide 769166 by 15.

On to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 15

On to step 2:
When dividing 76 by 15, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 1 after subtracting 75 from 76.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 15

Step 3:
The number 15 fits into 19 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtracting 15 from 19 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 15

Step 4:
If we divide 41 by 15, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 512.0
If we subtract 30 from 41, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 15

Going ahead to step 5:
15 goes into 116 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5127.0
Deduct 105 from 116 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 15

Going ahead to step 6:
15 can be fit into 116 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 51277.0
Subtract 105 from 116 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 51277.7
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 51277.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 51277.733
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 51277.733, with a leftover of 0.0005.
