We look at the division of 80156721 by 769 
We want to figure out the number of times 80156721 can be divided by 769.

On to step 1:
The number 769 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 769

Let's proceed to step 2:
769 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 769

Let's proceed to step 3:
769 goes into 801 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 769 from 801 and we're left with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 769

Going ahead to step 4:
When dividing 325 by 769, we get 0 with a remainder of 325.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 325, we end up with 325.
Append the next digit (6) from the dividend to 325 and continue with: 3256 / 769

Let's proceed to step 5:
The number 769 fits into 3256 4 times, leaving a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 3076 away from 3256, we end up with 180.
Take the next digit (7) from the dividend and append it to 180, then repeat: 1807 / 769

Going ahead to step 6:
769 goes into 1807 2 times with a remainder of 269.
Use 2 as the next digit of our solution. 
Result so far: 1042.0
Subtract 1538 from 1807 to get 269.
Grab the next digit (2) from the dividend, add it to 269, then carry on: 2692 / 769

Going ahead to step 7:
The number 769 fits into 2692 3 times, leaving a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 10423.0
Deduct 2307 from 2692 and we're left with 385.
Append the next digit (1) from the dividend to 385 and continue with: 3851 / 769

Moving on to step 8:
769 can be fit into 3851 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 104235.0
Subtract 3845 from 3851 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
769 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 104235.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 769 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 104235.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 104235.0 with a balance of 0.6.
