Let's divide 80431619 by 783
We want to divide 80431619 by 783.

Moving on to step 1:
783 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 783

Going ahead to step 2:
783 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
Subtract 0 from 80 to get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 783

Step 3:
The number 783 fits into 804 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 783 from 804, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 783

Step 4:
When dividing 213 by 783, we get 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 213 after subtracting 0 from 213.
Append the next digit (1) from the dividend to 213 and continue with: 2131 / 783

Let's proceed to step 5:
2131 divided by 783 is 2 with a remainder of 565.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 1566 from 2131 and we're left with 565.
Take the next digit (6) from the dividend and append it to 565, then repeat: 5656 / 783

Step 6:
783 goes into 5656 7 times with a remainder of 175.
Put 7 as the next digit of the answer. 
Result so far: 1027.0
If we take 5481 away from 5656, we end up with 175.
Take the next digit (1) from the dividend and append it to 175, then repeat: 1751 / 783

Moving on to step 7:
The number 783 fits into 1751 2 times, leaving a remainder of 185.
Write down 2 as next digit of the result. 
Result so far: 10272.0
Subtract 1566 from 1751 to get 185.
Grab the next digit (9) from the dividend, add it to 185, then carry on: 1859 / 783

Moving on to step 8:
When dividing 1859 by 783, we get 2 with a remainder of 293.
Use 2 as the next digit of our solution. 
Result so far: 102722.0
Subtract 1566 from 1859 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 9:
When dividing 2930 by 783, we get 3 with a remainder of 581.
Put 3 as the next digit of the answer. 
Result so far: 102722.3
Deduct 2349 from 2930 and we're left with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Advancing to step 10:
The number 783 fits into 5810 7 times, leaving a remainder of 329.
The next digit of our result is 7. 
Result so far: 102722.37
If we take 5481 away from 5810, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 11:
When dividing 3290 by 783, we get 4 with a remainder of 158.
The number 4 becomes the next digit in our result. 
Result so far: 102722.374
Deduct 3132 from 3290 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 12:
1580 divided by 783 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 102722.3742
Subtract 1566 from 1580 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
When dividing 140 by 783, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 102722.3742
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
783 can be fit into 1400 1 times, resulting in a remainder of 617.
The number 1 becomes the next digit in our result. 
Result so far: 102722.374201
If we subtract 783 from 1400, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 15:
When dividing 6170 by 783, we get 7 with a remainder of 689.
The next digit of our result is 7. 
Result so far: 102722.3742017
If we take 5481 away from 6170, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Moving on to step 16:
If we divide 6890 by 783, we get 8 and a remainder of 626.
Use 8 as the next digit of our solution. 
Result so far: 102722.37420178
If we subtract 6264 from 6890, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

After the division, we end up with 102722.37420178 and a remainder of 6.26e-07.
