20456419 ÷ 248 
Our goal is to divide 20456419 by 248.

Advancing to step 1:
If we divide 2 by 248, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 248

Let's proceed to step 2:
248 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 248

Moving on to step 3:
The number 248 fits into 204 0 times, leaving a remainder of 204.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Append the next digit (5) from the dividend to 204 and continue with: 2045 / 248

Going ahead to step 4:
If we divide 2045 by 248, we get 8 and a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 1984 from 2045 leaves us with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 248

Advancing to step 5:
248 can be fit into 616 2 times, resulting in a remainder of 120.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 496 from 616 to get 120.
Grab the next digit (4) from the dividend, add it to 120, then carry on: 1204 / 248

Step 6:
When dividing 1204 by 248, we get 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 824.0
Subtracting 992 from 1204 leaves us with 212.
Take the next digit (1) from the dividend and append it to 212, then repeat: 2121 / 248

Step 7:
When dividing 2121 by 248, we get 8 with a remainder of 137.
Write down 8 as next digit of the result. 
Result so far: 8248.0
If we subtract 1984 from 2121, we get 137.
Fetch the next digit (9) from the dividend, attach it to 137 and continue: 1379 / 248

Moving on to step 8:
248 goes into 1379 5 times with a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 82485.0
Deduct 1240 from 1379 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 9:
248 goes into 1390 5 times with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 82485.5
If we subtract 1240 from 1390, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
When dividing 1500 by 248, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 82485.56
Deduct 1488 from 1500 and we're left 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.

Let's proceed to step 11:
The number 248 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 82485.56
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
The number 248 fits into 1200 4 times, leaving a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 82485.5604
If we take 992 away from 1200, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 13:
If we divide 2080 by 248, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 82485.56048
Subtract 1984 from 2080 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
248 can be fit into 960 3 times, resulting in a remainder of 216.
Write down 3 as next digit of the result. 
Result so far: 82485.560483
The remainder is 216 after subtracting 744 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
248 goes into 2160 8 times with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 82485.5604838
If we take 1984 away from 2160, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
If we divide 1760 by 248, we get 7 and a remainder of 24.
The next digit of our result is 7. 
Result so far: 82485.56048387
If we take 1736 away from 1760, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 82485.56048387 with a remaining 2.4e-08.
