We look at the division of 21751989 by 270 
We're looking to find how many times 270 goes into 21751989.

Advancing to step 1:
When dividing 2 by 270, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 270

Going ahead to step 2:
21 divided by 270 is 0 with 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.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 270

On to step 3:
217 divided by 270 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Take the next digit (5) from the dividend and append it to 217, then repeat: 2175 / 270

Step 4:
270 goes into 2175 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 2160 from 2175 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 270

Let's proceed to step 5:
270 can be fit into 151 0 times, resulting in a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 151 and we're left with 151.
Append the next digit (9) from the dividend to 151 and continue with: 1519 / 270

Advancing to step 6:
The number 270 fits into 1519 5 times, leaving a remainder of 169.
Record the quotient 5 as the next digit in the result. 
Result so far: 805.0
If we take 1350 away from 1519, we end up with 169.
Take the next digit (8) from the dividend and append it to 169, then repeat: 1698 / 270

Going ahead to step 7:
270 goes into 1698 6 times with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 8056.0
Subtracting 1620 from 1698 leaves us with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 270

Moving on to step 8:
270 goes into 789 2 times with a remainder of 249.
Write down 2 as next digit of the result. 
Result so far: 80562.0
Subtracting 540 from 789 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 9:
When dividing 2490 by 270, we get 9 with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 80562.9
Subtract 2430 from 2490 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 270, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 80562.92
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
270 goes into 600 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 80562.922
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 80562.922 with a remaining 0.006.
