80029550 ÷ 140 
We want to divide 80029550 by 140.

Step 1:
140 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 140

Advancing to step 2:
140 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 140

Moving on to step 3:
If we divide 800 by 140, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 700 from 800 and we're left with 100.
Include the next digit (2) from the dividend after 100, then repeat: 1002 / 140

On to step 4:
140 goes into 1002 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 980 from 1002 and we're left with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 140

Moving on to step 5:
229 divided by 140 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 571.0
The remainder is 89 after subtracting 140 from 229.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 140

Moving on to step 6:
140 goes into 895 6 times with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 5716.0
Subtracting 840 from 895 leaves us with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 140

Let's proceed to step 7:
140 goes into 555 3 times with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 57163.0
Subtract 420 from 555 to get 135.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 140

Going ahead to step 8:
140 can be fit into 1350 9 times, resulting in a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 571639.0
Deduct 1260 from 1350 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
The number 140 fits into 900 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 571639.6
If we take 840 away from 900, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 140, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 571639.64
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 140 is 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 571639.642
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
140 goes into 1200 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 571639.6428
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
800 divided by 140 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 571639.64285
Subtracting 700 from 800 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 571639.642857
If we take 980 away from 1000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
The number 140 fits into 200 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 571639.6428571
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
If we divide 600 by 140, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 571639.64285714
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 571639.64285714 with a remaining 4e-08.
