We look at the division of 21173744 by 248 
Our goal is to divide 21173744 by 248.

Let's proceed to step 1:
248 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 248

On to step 2:
The number 248 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 248

Advancing to step 3:
211 divided by 248 is 0 with a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 248

On to step 4:
If we divide 2117 by 248, we get 8 and a remainder of 133.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 1984 from 2117 leaves us with 133.
Fetch the next digit (3) from the dividend, attach it to 133 and continue: 1333 / 248

Going ahead to step 5:
1333 divided by 248 is 5 with a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 93 after subtracting 1240 from 1333.
Append the next digit (7) from the dividend to 93 and continue with: 937 / 248

Advancing to step 6:
937 divided by 248 is 3 with a remainder of 193.
The next digit of our result is 3. 
Result so far: 853.0
If we take 744 away from 937, we end up with 193.
Bring next digit (4) of the dividend behind the 193 and repeat the process: 1934 / 248

Advancing to step 7:
The number 248 fits into 1934 7 times, leaving a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 8537.0
Deduct 1736 from 1934 and we're left with 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 248

On to step 8:
1984 divided by 248 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 85378.0
Subtract 1984 from 1984 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 248 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85378.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
248 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85378.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 85378.0 with a remaining 0.0.
