10780039 ÷ 139 
We're looking to find how many times 139 goes into 10780039.

Let's proceed to step 1:
139 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 139

Going ahead to step 2:
The number 139 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 139

Going ahead to step 3:
The number 139 fits into 107 0 times, leaving a remainder of 107.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 107 after subtracting 0 from 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 139

On to step 4:
139 can be fit into 1078 7 times, resulting in a remainder of 105.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 973 from 1078 and we're left with 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 139

Let's proceed to step 5:
If we divide 1050 by 139, we get 7 and a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 973 from 1050 to get 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 139

Going ahead to step 6:
139 can be fit into 770 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 775.0
Deduct 695 from 770 and we're left with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 139

Moving on to step 7:
If we divide 753 by 139, we get 5 and a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 7755.0
Subtract 695 from 753 to get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 139

Moving on to step 8:
When dividing 589 by 139, we get 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 77554.0
If we subtract 556 from 589, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
When dividing 330 by 139, we get 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 77554.2
Subtract 278 from 330 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 139 is 3 with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 77554.23
If we take 417 away from 520, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
139 goes into 1030 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 77554.237
Subtracting 973 from 1030 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
The number 139 fits into 570 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 77554.2374
If we subtract 556 from 570, we 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 139, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 77554.23741
Subtracting 139 from 140 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
The number 139 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 77554.23741
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
139 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 77554.23741
Deduct 0 from 100 and we're left 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.

After the division, we end up with 77554.23741 and a remainder of 1e-06.
