We look at the division of 21815544 by 274 
We want to divide 21815544 by 274.

Step 1:
When dividing 2 by 274, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 274

Let's proceed to step 2:
21 divided by 274 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 274

Step 3:
The number 274 fits into 218 0 times, leaving a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Grab the next digit (1) from the dividend, add it to 218, then carry on: 2181 / 274

Going ahead to step 4:
274 can be fit into 2181 7 times, resulting in a remainder of 263.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 1918 away from 2181, we end up with 263.
Include the next digit (5) from the dividend after 263, then repeat: 2635 / 274

Advancing to step 5:
When dividing 2635 by 274, we get 9 with a remainder of 169.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 2466 from 2635 and we're left with 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 274

Let's proceed to step 6:
274 goes into 1695 6 times with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 796.0
Deduct 1644 from 1695 and we're left with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 274

Let's proceed to step 7:
274 can be fit into 514 1 times, resulting in a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 7961.0
Subtract 274 from 514 to get 240.
Fetch the next digit (4) from the dividend, attach it to 240 and continue: 2404 / 274

Let's proceed to step 8:
274 can be fit into 2404 8 times, resulting in a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 79618.0
If we take 2192 away from 2404, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 9:
If we divide 2120 by 274, we get 7 and a remainder of 202.
The next digit of our result is 7. 
Result so far: 79618.7
Subtracting 1918 from 2120 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
If we divide 2020 by 274, we get 7 and a remainder of 102.
The next digit of our result is 7. 
Result so far: 79618.77
If we take 1918 away from 2020, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 79618.77 with a remaining 0.102.
