We're dividing 2511978 by 156 
We want to figure out the number of times 2511978 can be divided by 156.

Moving on to step 1:
When dividing 2 by 156, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 156

Step 2:
25 divided by 156 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 156

Advancing to step 3:
The number 156 fits into 251 1 times, leaving a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 156 from 251, we get 95.
Fetch the next digit (1) from the dividend, attach it to 95 and continue: 951 / 156

Moving on to step 4:
The number 156 fits into 951 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 936 from 951 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 156

Moving on to step 5:
The number 156 fits into 159 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 161.0
If we subtract 156 from 159, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 156

Advancing to step 6:
156 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 1610.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 156

Advancing to step 7:
156 can be fit into 378 2 times, resulting in a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 16102.0
The remainder is 66 after subtracting 312 from 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 156 fits into 660 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 16102.4
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
156 goes into 360 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 16102.42
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
156 can be fit into 480 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 16102.423
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 156 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 16102.423
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
156 can be fit into 1200 7 times, resulting in a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 16102.42307
If we take 1092 away from 1200, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 13:
If we divide 1080 by 156, we get 6 and a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 16102.423076
Subtracting 936 from 1080 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 14:
156 goes into 1440 9 times with a remainder of 36.
The next digit of our result is 9. 
Result so far: 16102.4230769
The remainder is 36 after subtracting 1404 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
If we divide 360 by 156, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 16102.42307692
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 16102.42307692, with a leftover of 4.8e-08.
