We look at the division of 12840958 by 147 
Our goal is to divide 12840958 by 147.

Going ahead to step 1:
When dividing 1 by 147, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 147

Moving on to step 2:
If we divide 12 by 147, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 147

Advancing to step 3:
147 goes into 128 0 times with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 147

Step 4:
The number 147 fits into 1284 8 times, leaving a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 1176 from 1284, we get 108.
Include the next digit (0) from the dividend after 108, then repeat: 1080 / 147

Let's proceed to step 5:
The number 147 fits into 1080 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 1029 from 1080 leaves us with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 147

Let's proceed to step 6:
When dividing 519 by 147, we get 3 with a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
Deduct 441 from 519 and we're left with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 147

Step 7:
When dividing 785 by 147, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8735.0
Subtracting 735 from 785 leaves us with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 147

Step 8:
147 can be fit into 508 3 times, resulting in a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 87353.0
If we subtract 441 from 508, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
147 can be fit into 670 4 times, resulting in a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 87353.4
If we take 588 away from 670, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
820 divided by 147 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 87353.45
If we subtract 735 from 820, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
If we divide 850 by 147, we get 5 and a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 87353.455
If we subtract 735 from 850, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final outcome is 87353.455, with a leftover of 0.0115.
