We divide 80171470 by 780
We're looking to find how many times 780 goes into 80171470.

Going ahead to step 1:
When dividing 8 by 780, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 780

Going ahead to step 2:
The number 780 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 780

Advancing to step 3:
780 can be fit into 801 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 780 from 801 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 780

Step 4:
When dividing 217 by 780, we get 0 with a remainder of 217.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 217, we end up with 217.
Grab the next digit (1) from the dividend, add it to 217, then carry on: 2171 / 780

Step 5:
2171 divided by 780 is 2 with a remainder of 611.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 611 after subtracting 1560 from 2171.
Append the next digit (4) from the dividend to 611 and continue with: 6114 / 780

Step 6:
780 goes into 6114 7 times with a remainder of 654.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
Subtract 5460 from 6114 to get 654.
Bring next digit (7) of the dividend behind the 654 and repeat the process: 6547 / 780

Moving on to step 7:
780 goes into 6547 8 times with a remainder of 307.
Record the quotient 8 as the next digit in the result. 
Result so far: 10278.0
If we take 6240 away from 6547, we end up with 307.
Bring next digit (0) of the dividend behind the 307 and repeat the process: 3070 / 780

Step 8:
780 can be fit into 3070 3 times, resulting in a remainder of 730.
Record the quotient 3 as the next digit in the result. 
Result so far: 102783.0
Subtracting 2340 from 3070 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 9:
780 can be fit into 7300 9 times, resulting in a remainder of 280.
The next digit of our result is 9. 
Result so far: 102783.9
Subtracting 7020 from 7300 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
2800 divided by 780 is 3 with a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 102783.93
Subtract 2340 from 2800 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
The number 780 fits into 4600 5 times, leaving a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 102783.935
If we subtract 3900 from 4600, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 12:
780 can be fit into 7000 8 times, resulting in a remainder of 760.
Record the quotient 8 as the next digit in the result. 
Result so far: 102783.9358
Subtracting 6240 from 7000 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 13:
780 can be fit into 7600 9 times, resulting in a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 102783.93589
Subtract 7020 from 7600 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 14:
The number 780 fits into 5800 7 times, leaving a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 102783.935897
Subtracting 5460 from 5800 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
780 goes into 3400 4 times with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 102783.9358974
Subtracting 3120 from 3400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
If we divide 2800 by 780, we get 3 and a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 102783.93589743
Deduct 2340 from 2800 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The quotient of the division is 102783.93589743, and the remainder is 4.6e-07.
