We're dividing 30139109 by 156 
We want to figure out the number of times 30139109 can be divided by 156.

Let's proceed to step 1:
156 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 156

Let's proceed to step 2:
If we divide 30 by 156, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 156

Moving on to step 3:
301 divided by 156 is 1 with a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 156 away from 301, we end up with 145.
Bring next digit (3) of the dividend behind the 145 and repeat the process: 1453 / 156

Step 4:
When dividing 1453 by 156, we get 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 49 after subtracting 1404 from 1453.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 156

Step 5:
156 goes into 499 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 193.0
If we take 468 away from 499, we end up with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 156

Step 6:
The number 156 fits into 311 1 times, leaving a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 1931.0
Deduct 156 from 311 and we're left with 155.
Take the next digit (0) from the dividend and append it to 155, then repeat: 1550 / 156

Going ahead to step 7:
When dividing 1550 by 156, we get 9 with a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 19319.0
Subtracting 1404 from 1550 leaves us with 146.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 156

Step 8:
When dividing 1469 by 156, we get 9 with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 193199.0
Deduct 1404 from 1469 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
156 can be fit into 650 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 193199.4
The remainder is 26 after subtracting 624 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
When dividing 260 by 156, we get 1 with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 193199.41
If we take 156 away from 260, we end up 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.

On to step 11:
156 goes into 1040 6 times with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 193199.416
Subtract 936 from 1040 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
1040 divided by 156 is 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 193199.4166
The remainder is 104 after subtracting 936 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 193199.4166 with a remainder of 0.00104.
