We look at the division of 21219554 by 248 
Let's see how many times 248 fits into 21219554.

Advancing to step 1:
The number 248 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 248

Let's proceed to step 2:
If we divide 21 by 248, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 248

Let's proceed to step 3:
248 goes into 212 0 times with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 248

Step 4:
The number 248 fits into 2121 8 times, leaving a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 1984 away from 2121, we end up with 137.
Take the next digit (9) from the dividend and append it to 137, then repeat: 1379 / 248

Moving on to step 5:
If we divide 1379 by 248, we get 5 and a remainder of 139.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 1240 from 1379, we get 139.
Take the next digit (5) from the dividend and append it to 139, then repeat: 1395 / 248

Let's proceed to step 6:
The number 248 fits into 1395 5 times, leaving a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 855.0
If we subtract 1240 from 1395, we get 155.
Grab the next digit (5) from the dividend, add it to 155, then carry on: 1555 / 248

Let's proceed to step 7:
When dividing 1555 by 248, we get 6 with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 8556.0
Subtracting 1488 from 1555 leaves us with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 248

Going ahead to step 8:
674 divided by 248 is 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 85562.0
If we take 496 away from 674, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
If we divide 1780 by 248, we get 7 and a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 85562.7
Deduct 1736 from 1780 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 248, we get 1 and a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 85562.71
Subtracting 248 from 440 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
1920 divided by 248 is 7 with a remainder of 184.
The number 7 becomes the next digit in our result. 
Result so far: 85562.717
The remainder is 184 after subtracting 1736 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
248 can be fit into 1840 7 times, resulting in a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 85562.7177
If we subtract 1736 from 1840, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 85562.7177, and the remainder is 0.00104.
