We divide 19990961 by 139
Let's see how many times 139 fits into 19990961.

Moving on to step 1:
When dividing 1 by 139, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 139

Going ahead to step 2:
The number 139 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 139

Advancing to step 3:
139 goes into 199 1 times with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 139 from 199 to get 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 139

Advancing to step 4:
139 can be fit into 609 4 times, resulting in a remainder of 53.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 556 from 609 to get 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 139

Step 5:
When dividing 530 by 139, we get 3 with a remainder of 113.
The next digit of our result is 3. 
Result so far: 143.0
The remainder is 113 after subtracting 417 from 530.
Take the next digit (9) from the dividend and append it to 113, then repeat: 1139 / 139

Step 6:
1139 divided by 139 is 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 1438.0
Subtracting 1112 from 1139 leaves us with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 139

Moving on to step 7:
When dividing 276 by 139, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 14381.0
The remainder is 137 after subtracting 139 from 276.
Include the next digit (1) from the dividend after 137, then repeat: 1371 / 139

Advancing to step 8:
If we divide 1371 by 139, we get 9 and a remainder of 120.
The next digit of our result is 9. 
Result so far: 143819.0
The remainder is 120 after subtracting 1251 from 1371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
If we divide 1200 by 139, we get 8 and a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 143819.8
The remainder is 88 after subtracting 1112 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 10:
139 goes into 880 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 143819.86
Deduct 834 from 880 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
If we divide 460 by 139, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 143819.863
Subtracting 417 from 460 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 12:
If we divide 430 by 139, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 143819.8633
If we take 417 away from 430, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 143819.8633 and a remainder of 0.00013.
