19965715 divided by 139 
We're looking to find how many times 139 goes into 19965715.

Moving on to step 1:
139 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 139

Going ahead to step 2:
19 divided by 139 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 139

Let's proceed to step 3:
199 divided by 139 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 60 after subtracting 139 from 199.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 139

Moving on to step 4:
139 goes into 606 4 times with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 50 after subtracting 556 from 606.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 139

Let's proceed to step 5:
The number 139 fits into 505 3 times, leaving a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Subtract 417 from 505 to get 88.
Append the next digit (7) from the dividend to 88 and continue with: 887 / 139

Let's proceed to step 6:
If we divide 887 by 139, we get 6 and a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 1436.0
The remainder is 53 after subtracting 834 from 887.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 139

Advancing to step 7:
The number 139 fits into 531 3 times, leaving a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 14363.0
The remainder is 114 after subtracting 417 from 531.
Bring next digit (5) of the dividend behind the 114 and repeat the process: 1145 / 139

Moving on to step 8:
139 can be fit into 1145 8 times, resulting in a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 143638.0
If we take 1112 away from 1145, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
When dividing 330 by 139, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 143638.2
Subtracting 278 from 330 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
520 divided by 139 is 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 143638.23
Subtracting 417 from 520 leaves us 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:
1030 divided by 139 is 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 143638.237
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.

Advancing to step 12:
139 goes into 570 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 143638.2374
Subtracting 556 from 570 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
139 can be fit into 140 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 143638.23741
If we subtract 139 from 140, we get 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:
139 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 143638.23741
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
When dividing 100 by 139, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 143638.23741
The remainder is 100 after subtracting 0 from 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 143638.23741 and a remainder of 1e-06.
