We're dividing 39906258 by 154 
We want to divide 39906258 by 154.

On to step 1:
3 divided by 154 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 154

Let's proceed to step 2:
154 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 154

Let's proceed to step 3:
When dividing 399 by 154, we get 2 with a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 91 after subtracting 308 from 399.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 154

On to step 4:
The number 154 fits into 910 5 times, leaving a remainder of 140.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 140 after subtracting 770 from 910.
Append the next digit (6) from the dividend to 140 and continue with: 1406 / 154

Moving on to step 5:
The number 154 fits into 1406 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 259.0
Subtract 1386 from 1406 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 154

Going ahead to step 6:
202 divided by 154 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 2591.0
Subtracting 154 from 202 leaves us with 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 154

Let's proceed to step 7:
When dividing 485 by 154, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 25913.0
If we subtract 462 from 485, we get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 154

Moving on to step 8:
154 can be fit into 238 1 times, resulting in a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 259131.0
Subtracting 154 from 238 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
154 goes into 840 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 259131.5
If we take 770 away from 840, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
The number 154 fits into 700 4 times, leaving a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 259131.54
If we take 616 away from 700, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
840 divided by 154 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 259131.545
Subtracting 770 from 840 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
When dividing 700 by 154, we get 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 259131.5454
Subtracting 616 from 700 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
The number 154 fits into 840 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 259131.54545
Subtracting 770 from 840 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
700 divided by 154 is 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 259131.545454
If we subtract 616 from 700, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
154 goes into 840 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 259131.5454545
The remainder is 70 after subtracting 770 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
If we divide 700 by 154, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 259131.54545454
The remainder is 84 after subtracting 616 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 259131.54545454 and a remainder of 8.4e-08.
