80458341 ÷ 140 
We're looking to find how many times 140 goes into 80458341.

Advancing to step 1:
When dividing 8 by 140, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 140

Moving on to step 2:
The number 140 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 140

Step 3:
140 goes into 804 5 times with a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 700 from 804 leaves us with 104.
Fetch the next digit (5) from the dividend, attach it to 104 and continue: 1045 / 140

On to step 4:
140 goes into 1045 7 times with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 980 from 1045 and we're left with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 140

On to step 5:
When dividing 658 by 140, we get 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
Subtract 560 from 658 to get 98.
Grab the next digit (3) from the dividend, add it to 98, then carry on: 983 / 140

Moving on to step 6:
140 can be fit into 983 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5747.0
Subtract 980 from 983 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 140

Moving on to step 7:
The number 140 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 57470.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 140

On to step 8:
The number 140 fits into 341 2 times, leaving a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 574702.0
If we subtract 280 from 341, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
If we divide 610 by 140, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 574702.4
The remainder is 50 after subtracting 560 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 140 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 574702.43
If we take 420 away from 500, we end up with 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 11:
800 divided by 140 is 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 574702.435
If we subtract 700 from 800, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
If we divide 1000 by 140, we get 7 and a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 574702.4357
Deduct 980 from 1000 and we're left 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.

Advancing to step 13:
The number 140 fits into 200 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 574702.43571
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
140 goes into 600 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 574702.435714
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
140 can be fit into 400 2 times, resulting in a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 574702.4357142
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
The number 140 fits into 1200 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 574702.43571428
Subtract 1120 from 1200 to 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.

The final outcome is 574702.43571428, with a leftover of 8e-08.
