80399687 ÷ 248 
We're looking to find how many times 248 goes into 80399687.

Step 1:
248 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 248

Moving on to step 2:
80 divided by 248 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 248

On to step 3:
If we divide 803 by 248, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 744 from 803, we get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 248

Moving on to step 4:
248 goes into 599 2 times with a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 496 from 599, we get 103.
Fetch the next digit (9) from the dividend, attach it to 103 and continue: 1039 / 248

On to step 5:
248 can be fit into 1039 4 times, resulting in a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 324.0
Subtracting 992 from 1039 leaves us with 47.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 248

Step 6:
248 can be fit into 476 1 times, resulting in a remainder of 228.
Put 1 as the next digit of the answer. 
Result so far: 3241.0
If we subtract 248 from 476, we get 228.
Take the next digit (8) from the dividend and append it to 228, then repeat: 2288 / 248

Moving on to step 7:
The number 248 fits into 2288 9 times, leaving a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 32419.0
Subtract 2232 from 2288 to get 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 248

Moving on to step 8:
248 goes into 567 2 times with a remainder of 71.
The next digit of our result is 2. 
Result so far: 324192.0
If we take 496 away from 567, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
248 goes into 710 2 times with a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 324192.2
The remainder is 214 after subtracting 496 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 10:
The number 248 fits into 2140 8 times, leaving a remainder of 156.
The next digit of our result is 8. 
Result so far: 324192.28
Subtracting 1984 from 2140 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
If we divide 1560 by 248, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 324192.286
Deduct 1488 from 1560 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.

Let's proceed to step 12:
When dividing 720 by 248, we get 2 with a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 324192.2862
Subtracting 496 from 720 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 13:
248 can be fit into 2240 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 324192.28629
Deduct 2232 from 2240 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
248 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 324192.28629
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 248 fits into 800 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 324192.2862903
The remainder is 56 after subtracting 744 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
When dividing 560 by 248, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 324192.28629032
If we subtract 496 from 560, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 324192.28629032, and the remainder is 6.4e-08.
