We look at the division of 1140646 by 156 
Let's see how many times 156 fits into 1140646.

Let's proceed to step 1:
156 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 156

On to step 2:
156 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 156

Let's proceed to step 3:
If we divide 114 by 156, we get 0 and a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 114 after subtracting 0 from 114.
Fetch the next digit (0) from the dividend, attach it to 114 and continue: 1140 / 156

Going ahead to step 4:
If we divide 1140 by 156, we get 7 and a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 1092 away from 1140, we end up with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 156

Advancing to step 5:
When dividing 486 by 156, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 73.0
If we take 468 away from 486, we end up with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 156

Let's proceed to step 6:
When dividing 184 by 156, we get 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
If we subtract 156 from 184, we get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 156

Moving on to step 7:
156 goes into 286 1 times with a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 7311.0
Subtract 156 from 286 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 8:
When dividing 1300 by 156, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 7311.8
Deduct 1248 from 1300 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.

Moving on to step 9:
156 can be fit into 520 3 times, resulting in a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 7311.83
If we take 468 away from 520, we end up 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.

Let's proceed to step 10:
156 can be fit into 520 3 times, resulting in a remainder of 52.
The next digit of our result is 3. 
Result so far: 7311.833
The remainder is 52 after subtracting 468 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 7311.833 with a remainder of 0.0052.
