We're dividing 99540721 by 254 
Our goal is to divide 99540721 by 254.

Step 1:
254 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 254

Moving on to step 2:
99 divided by 254 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 254

Advancing to step 3:
The number 254 fits into 995 3 times, leaving a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 762 from 995, we get 233.
Include the next digit (4) from the dividend after 233, then repeat: 2334 / 254

Let's proceed to step 4:
254 goes into 2334 9 times with a remainder of 48.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 2286 from 2334 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 254

Let's proceed to step 5:
When dividing 480 by 254, we get 1 with a remainder of 226.
The next digit of our result is 1. 
Result so far: 391.0
Subtracting 254 from 480 leaves us with 226.
Grab the next digit (7) from the dividend, add it to 226, then carry on: 2267 / 254

Going ahead to step 6:
254 can be fit into 2267 8 times, resulting in a remainder of 235.
Write down 8 as next digit of the result. 
Result so far: 3918.0
Subtracting 2032 from 2267 leaves us with 235.
Append the next digit (2) from the dividend to 235 and continue with: 2352 / 254

Advancing to step 7:
When dividing 2352 by 254, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 39189.0
If we take 2286 away from 2352, we end up with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 254

Going ahead to step 8:
661 divided by 254 is 2 with a remainder of 153.
Record the quotient 2 as the next digit in the result. 
Result so far: 391892.0
If we subtract 508 from 661, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
If we divide 1530 by 254, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 391892.6
The remainder is 6 after subtracting 1524 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
254 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 391892.6
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 254 is 2 with a remainder of 92.
The next digit of our result is 2. 
Result so far: 391892.602
The remainder is 92 after subtracting 508 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
920 divided by 254 is 3 with a remainder of 158.
Use 3 as the next digit of our solution. 
Result so far: 391892.6023
If we take 762 away from 920, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 13:
254 can be fit into 1580 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 391892.60236
The remainder is 56 after subtracting 1524 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
560 divided by 254 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 391892.602362
Deduct 508 from 560 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
If we divide 520 by 254, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 391892.6023622
Subtracting 508 from 520 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 391892.6023622 with a remaining 1.2e-07.
