We're dividing 38949980 by 253 
Let's see how many times 253 fits into 38949980.

Going ahead to step 1:
The number 253 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 253

On to step 2:
38 divided by 253 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 253

Let's proceed to step 3:
253 can be fit into 389 1 times, resulting in a remainder of 136.
The next digit of our result is 1. 
Result so far: 1.0
If we take 253 away from 389, we end up with 136.
Grab the next digit (4) from the dividend, add it to 136, then carry on: 1364 / 253

On to step 4:
The number 253 fits into 1364 5 times, leaving a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1265 from 1364, we get 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 253

Step 5:
253 can be fit into 999 3 times, resulting in a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 153.0
The remainder is 240 after subtracting 759 from 999.
Grab the next digit (9) from the dividend, add it to 240, then carry on: 2409 / 253

Moving on to step 6:
253 goes into 2409 9 times with a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 1539.0
Subtracting 2277 from 2409 leaves us with 132.
Bring next digit (8) of the dividend behind the 132 and repeat the process: 1328 / 253

On to step 7:
The number 253 fits into 1328 5 times, leaving a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 15395.0
Subtracting 1265 from 1328 leaves us with 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 253

On to step 8:
253 can be fit into 630 2 times, resulting in a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 153952.0
If we take 506 away from 630, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
1240 divided by 253 is 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 153952.4
Subtracting 1012 from 1240 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
2280 divided by 253 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 153952.49
If we take 2277 away from 2280, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
253 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 153952.49
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 253 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 153952.4901
If we take 253 away from 300, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
When dividing 470 by 253, we get 1 with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 153952.49011
Subtracting 253 from 470 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

The final result is 153952.49011 with a remainder of 0.000217.
