53408003 ÷ 248 
We want to divide 53408003 by 248.

Step 1:
The number 248 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 248

Advancing to step 2:
When dividing 53 by 248, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 248

Moving on to step 3:
If we divide 534 by 248, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 38 after subtracting 496 from 534.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 248

Advancing to step 4:
248 goes into 380 1 times with a remainder of 132.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 248 from 380, we get 132.
Take the next digit (8) from the dividend and append it to 132, then repeat: 1328 / 248

On to step 5:
248 goes into 1328 5 times with a remainder of 88.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
If we take 1240 away from 1328, we end up with 88.
Grab the next digit (0) from the dividend, add it to 88, then carry on: 880 / 248

Step 6:
When dividing 880 by 248, we get 3 with a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 2153.0
The remainder is 136 after subtracting 744 from 880.
Bring next digit (0) of the dividend behind the 136 and repeat the process: 1360 / 248

Advancing to step 7:
248 goes into 1360 5 times with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 21535.0
If we take 1240 away from 1360, we end up with 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 248

Going ahead to step 8:
248 can be fit into 1203 4 times, resulting in a remainder of 211.
Write down 4 as next digit of the result. 
Result so far: 215354.0
If we take 992 away from 1203, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 9:
248 goes into 2110 8 times with a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 215354.8
The remainder is 126 after subtracting 1984 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
248 can be fit into 1260 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 215354.85
Subtract 1240 from 1260 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 248 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 215354.85
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
The number 248 fits into 2000 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 215354.8508
If we subtract 1984 from 2000, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 248 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 215354.8508
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
248 goes into 1600 6 times with a remainder of 112.
The next digit of our result is 6. 
Result so far: 215354.850806
If we subtract 1488 from 1600, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
1120 divided by 248 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 215354.8508064
If we take 992 away from 1120, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
If we divide 1280 by 248, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 215354.85080645
Subtracting 1240 from 1280 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 215354.85080645 with a remaining 4e-08.
