80177370 ÷ 781 
We want to figure out the number of times 80177370 can be divided by 781.

On to step 1:
8 divided by 781 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 781

Moving on to step 2:
When dividing 80 by 781, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 781

Moving on to step 3:
781 goes into 801 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 781 from 801 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 781

Going ahead to step 4:
If we divide 207 by 781, we get 0 and a remainder of 207.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 207 to get 207.
Grab the next digit (7) from the dividend, add it to 207, then carry on: 2077 / 781

Moving on to step 5:
2077 divided by 781 is 2 with a remainder of 515.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we subtract 1562 from 2077, we get 515.
Take the next digit (3) from the dividend and append it to 515, then repeat: 5153 / 781

Advancing to step 6:
If we divide 5153 by 781, we get 6 and a remainder of 467.
The next digit of our result is 6. 
Result so far: 1026.0
Deduct 4686 from 5153 and we're left with 467.
Append the next digit (7) from the dividend to 467 and continue with: 4677 / 781

Moving on to step 7:
When dividing 4677 by 781, we get 5 with a remainder of 772.
The number 5 becomes the next digit in our result. 
Result so far: 10265.0
If we subtract 3905 from 4677, we get 772.
Bring next digit (0) of the dividend behind the 772 and repeat the process: 7720 / 781

Let's proceed to step 8:
The number 781 fits into 7720 9 times, leaving a remainder of 691.
Use 9 as the next digit of our solution. 
Result so far: 102659.0
If we subtract 7029 from 7720, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 9:
If we divide 6910 by 781, we get 8 and a remainder of 662.
The number 8 becomes the next digit in our result. 
Result so far: 102659.8
If we subtract 6248 from 6910, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 10:
781 can be fit into 6620 8 times, resulting in a remainder of 372.
Put 8 as the next digit of the answer. 
Result so far: 102659.88
The remainder is 372 after subtracting 6248 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The quotient of the division is 102659.88, and the remainder is 0.372.
