Let's divide 20150109 by 157
We want to divide 20150109 by 157.

Going ahead to step 1:
The number 157 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 157

Going ahead to step 2:
If we divide 20 by 157, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 157

On to step 3:
The number 157 fits into 201 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 157 from 201 leaves us with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 157

On to step 4:
If we divide 445 by 157, we get 2 and a remainder of 131.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 131 after subtracting 314 from 445.
Take the next digit (0) from the dividend and append it to 131, then repeat: 1310 / 157

On to step 5:
157 goes into 1310 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 1256 from 1310 to get 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 157

Let's proceed to step 6:
When dividing 541 by 157, we get 3 with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 1283.0
Subtracting 471 from 541 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 157

On to step 7:
157 can be fit into 700 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 12834.0
Deduct 628 from 700 and we're left with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 157

Advancing to step 8:
729 divided by 157 is 4 with a remainder of 101.
The next digit of our result is 4. 
Result so far: 128344.0
Subtract 628 from 729 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
When dividing 1010 by 157, we get 6 with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 128344.6
Subtract 942 from 1010 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
When dividing 680 by 157, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 128344.64
Deduct 628 from 680 and we're left 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 11:
The number 157 fits into 520 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 128344.643
The remainder is 49 after subtracting 471 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
The number 157 fits into 490 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 128344.6433
Subtract 471 from 490 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 128344.6433 and a remainder of 0.00019.
