We look at the division of 12408620 by 768 
We're looking to find how many times 768 goes into 12408620.

On to step 1:
The number 768 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 768

Advancing to step 2:
If we divide 12 by 768, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 768

Advancing to step 3:
The number 768 fits into 124 0 times, leaving a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Append the next digit (0) from the dividend to 124 and continue with: 1240 / 768

Step 4:
768 goes into 1240 1 times with a remainder of 472.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 768 from 1240 to get 472.
Fetch the next digit (8) from the dividend, attach it to 472 and continue: 4728 / 768

Advancing to step 5:
768 can be fit into 4728 6 times, resulting in a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 4608 away from 4728, we end up with 120.
Append the next digit (6) from the dividend to 120 and continue with: 1206 / 768

Advancing to step 6:
If we divide 1206 by 768, we get 1 and a remainder of 438.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we take 768 away from 1206, we end up with 438.
Take the next digit (2) from the dividend and append it to 438, then repeat: 4382 / 768

Step 7:
The number 768 fits into 4382 5 times, leaving a remainder of 542.
Record the quotient 5 as the next digit in the result. 
Result so far: 1615.0
The remainder is 542 after subtracting 3840 from 4382.
Append the next digit (0) from the dividend to 542 and continue with: 5420 / 768

Let's proceed to step 8:
If we divide 5420 by 768, we get 7 and a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 16157.0
If we take 5376 away from 5420, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 768, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 16157.0
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
When dividing 4400 by 768, we get 5 with a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 16157.05
If we subtract 3840 from 4400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
5600 divided by 768 is 7 with a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 16157.057
If we take 5376 away from 5600, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
The number 768 fits into 2240 2 times, leaving a remainder of 704.
Put 2 as the next digit of the answer. 
Result so far: 16157.0572
If we subtract 1536 from 2240, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 13:
768 goes into 7040 9 times with a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 16157.05729
If we subtract 6912 from 7040, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
The number 768 fits into 1280 1 times, leaving a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 16157.057291
Deduct 768 from 1280 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 15:
5120 divided by 768 is 6 with a remainder of 512.
The next digit of our result is 6. 
Result so far: 16157.0572916
If we take 4608 away from 5120, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 16:
When dividing 5120 by 768, we get 6 with a remainder of 512.
The number 6 becomes the next digit in our result. 
Result so far: 16157.05729166
Deduct 4608 from 5120 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final outcome is 16157.05729166, with a leftover of 5.12e-07.
