We divide 20099390 by 139
We're looking to find how many times 139 goes into 20099390.

Advancing to step 1:
139 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 139

On to step 2:
20 divided by 139 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 139

Advancing to step 3:
The number 139 fits into 200 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 61 after subtracting 139 from 200.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 139

Moving on to step 4:
If we divide 619 by 139, we get 4 and a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 556 from 619, we get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 139

Moving on to step 5:
When dividing 639 by 139, we get 4 with a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 556 from 639 and we're left with 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 139

Moving on to step 6:
When dividing 833 by 139, we get 5 with a remainder of 138.
Write down 5 as next digit of the result. 
Result so far: 1445.0
Subtracting 695 from 833 leaves us with 138.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 139

Let's proceed to step 7:
The number 139 fits into 1389 9 times, leaving a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 14459.0
If we take 1251 away from 1389, we end up with 138.
Include the next digit (0) from the dividend after 138, then repeat: 1380 / 139

Let's proceed to step 8:
139 goes into 1380 9 times with a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 144599.0
Deduct 1251 from 1380 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
If we divide 1290 by 139, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 144599.9
If we take 1251 away from 1290, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
When dividing 390 by 139, we get 2 with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 144599.92
Deduct 278 from 390 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
When dividing 1120 by 139, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 144599.928
Subtract 1112 from 1120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
139 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 144599.928
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
When dividing 800 by 139, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 144599.92805
Deduct 695 from 800 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 14:
When dividing 1050 by 139, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 144599.928057
Subtracting 973 from 1050 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 15:
If we divide 770 by 139, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 144599.9280575
If we subtract 695 from 770, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
The number 139 fits into 750 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 144599.92805755
If we take 695 away from 750, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 144599.92805755 with a remainder of 5.5e-08.
