15057966 divided by 139 
We're looking to find how many times 139 goes into 15057966.

On to step 1:
When dividing 1 by 139, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 139

Advancing to step 2:
15 divided by 139 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 139

On to step 3:
If we divide 150 by 139, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 139 from 150 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 139

Let's proceed to step 4:
115 divided by 139 is 0 with a remainder of 115.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 115 leaves us with 115.
Fetch the next digit (7) from the dividend, attach it to 115 and continue: 1157 / 139

Step 5:
When dividing 1157 by 139, we get 8 with a remainder of 45.
The next digit of our result is 8. 
Result so far: 108.0
If we subtract 1112 from 1157, we get 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 139

Let's proceed to step 6:
139 goes into 459 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
If we take 417 away from 459, we end up with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 139

Going ahead to step 7:
The number 139 fits into 426 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 10833.0
If we take 417 away from 426, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 139

Step 8:
The number 139 fits into 96 0 times, leaving a remainder of 96.
Put 0 as the next digit of the answer. 
Result so far: 108330.0
If we subtract 0 from 96, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
960 divided by 139 is 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 108330.6
If we take 834 away from 960, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
139 can be fit into 1260 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 108330.69
Subtract 1251 from 1260 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
139 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 108330.69
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
139 can be fit into 900 6 times, resulting in a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 108330.6906
Subtracting 834 from 900 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
660 divided by 139 is 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 108330.69064
Deduct 556 from 660 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 14:
When dividing 1040 by 139, we get 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 108330.690647
Deduct 973 from 1040 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 15:
139 goes into 670 4 times with a remainder of 114.
The next digit of our result is 4. 
Result so far: 108330.6906474
Subtracting 556 from 670 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 16:
When dividing 1140 by 139, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 108330.69064748
If we subtract 1112 from 1140, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 108330.69064748, and the remainder is 2.8e-08.
