We look at the division of 39646809 by 153 
We want to divide 39646809 by 153.

Advancing to step 1:
If we divide 3 by 153, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 153

Let's proceed to step 2:
153 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 153

Step 3:
153 goes into 396 2 times with a remainder of 90.
The next digit of our result is 2. 
Result so far: 2.0
If we take 306 away from 396, we end up with 90.
Take the next digit (4) from the dividend and append it to 90, then repeat: 904 / 153

Going ahead to step 4:
If we divide 904 by 153, we get 5 and a remainder of 139.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 765 from 904 leaves us with 139.
Bring next digit (6) of the dividend behind the 139 and repeat the process: 1396 / 153

On to step 5:
153 can be fit into 1396 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
The remainder is 19 after subtracting 1377 from 1396.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 153

Advancing to step 6:
153 goes into 198 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 2591.0
If we take 153 away from 198, we end up with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 153

Advancing to step 7:
153 can be fit into 450 2 times, resulting in a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 25912.0
If we take 306 away from 450, we end up with 144.
Grab the next digit (9) from the dividend, add it to 144, then carry on: 1449 / 153

Going ahead to step 8:
If we divide 1449 by 153, we get 9 and a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 259129.0
Deduct 1377 from 1449 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
153 goes into 720 4 times with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 259129.4
If we subtract 612 from 720, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
If we divide 1080 by 153, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 259129.47
If we take 1071 away from 1080, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
153 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 259129.47
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
900 divided by 153 is 5 with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 259129.4705
If we take 765 away from 900, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 13:
When dividing 1350 by 153, we get 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 259129.47058
Subtract 1224 from 1350 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 14:
The number 153 fits into 1260 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 259129.470588
Subtracting 1224 from 1260 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.

The final result is 259129.470588 with a remainder of 3.6e-06.
