We're dividing 39860862 by 154 
Let's see how many times 154 fits into 39860862.

On to step 1:
154 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 154

Advancing to step 2:
When dividing 39 by 154, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 154

Going ahead to step 3:
The number 154 fits into 398 2 times, leaving a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 308 from 398, we get 90.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 154

On to step 4:
906 divided by 154 is 5 with a remainder of 136.
The next digit of our result is 5. 
Result so far: 25.0
If we take 770 away from 906, we end up with 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 154

On to step 5:
The number 154 fits into 1360 8 times, leaving a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 258.0
The remainder is 128 after subtracting 1232 from 1360.
Grab the next digit (8) from the dividend, add it to 128, then carry on: 1288 / 154

Advancing to step 6:
When dividing 1288 by 154, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 2588.0
Subtracting 1232 from 1288 leaves us with 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 154

Moving on to step 7:
566 divided by 154 is 3 with a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 25883.0
The remainder is 104 after subtracting 462 from 566.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 154

Step 8:
If we divide 1042 by 154, we get 6 and a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 258836.0
Deduct 924 from 1042 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
If we divide 1180 by 154, we get 7 and a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 258836.7
Subtract 1078 from 1180 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 10:
If we divide 1020 by 154, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 258836.76
If we take 924 away from 1020, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
154 goes into 960 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 258836.766
If we subtract 924 from 960, we get 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 quotient of the division is 258836.766, and the remainder is 0.0036.
