77804423 ÷ 140 
We want to divide 77804423 by 140.

Moving on to step 1:
The number 140 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 140

Advancing to step 2:
140 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 140

On to step 3:
The number 140 fits into 778 5 times, leaving a remainder of 78.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 700 away from 778, we end up with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 140

Step 4:
The number 140 fits into 780 5 times, leaving a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 700 from 780, we get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 140

Step 5:
140 can be fit into 804 5 times, resulting in a remainder of 104.
The next digit of our result is 5. 
Result so far: 555.0
The remainder is 104 after subtracting 700 from 804.
Take the next digit (4) from the dividend and append it to 104, then repeat: 1044 / 140

Let's proceed to step 6:
1044 divided by 140 is 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 5557.0
If we take 980 away from 1044, we end up with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 140

Step 7:
If we divide 642 by 140, we get 4 and a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 55574.0
The remainder is 82 after subtracting 560 from 642.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 140

Going ahead to step 8:
The number 140 fits into 823 5 times, leaving a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 555745.0
If we subtract 700 from 823, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 9:
140 goes into 1230 8 times with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 555745.8
If we subtract 1120 from 1230, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
If we divide 1100 by 140, we get 7 and a remainder of 120.
The next digit of our result is 7. 
Result so far: 555745.87
Deduct 980 from 1100 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.

Step 11:
140 goes into 1200 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 555745.878
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.

Let's proceed to step 12:
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: 555745.8785
The remainder is 100 after subtracting 700 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
1000 divided by 140 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 555745.87857
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.

Let's proceed to step 14:
If we divide 200 by 140, we get 1 and a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 555745.878571
Subtract 140 from 200 to get 60.
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 15:
When dividing 600 by 140, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 555745.8785714
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.

Step 16:
400 divided by 140 is 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 555745.87857142
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.

The final outcome is 555745.87857142, with a leftover of 1.2e-07.
