We look at the division of 21790281 by 603 
We're looking to find how many times 603 goes into 21790281.

Step 1:
The number 603 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 603

On to step 2:
603 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 603

Advancing to step 3:
217 divided by 603 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 603

Moving on to step 4:
603 can be fit into 2179 3 times, resulting in a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 370 after subtracting 1809 from 2179.
Grab the next digit (0) from the dividend, add it to 370, then carry on: 3700 / 603

Step 5:
The number 603 fits into 3700 6 times, leaving a remainder of 82.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 3618 from 3700 and we're left with 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 603

On to step 6:
The number 603 fits into 822 1 times, leaving a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
Subtract 603 from 822 to get 219.
Append the next digit (8) from the dividend to 219 and continue with: 2198 / 603

Let's proceed to step 7:
603 can be fit into 2198 3 times, resulting in a remainder of 389.
The next digit of our result is 3. 
Result so far: 3613.0
If we take 1809 away from 2198, we end up with 389.
Append the next digit (1) from the dividend to 389 and continue with: 3891 / 603

Going ahead to step 8:
If we divide 3891 by 603, we get 6 and a remainder of 273.
The next digit of our result is 6. 
Result so far: 36136.0
Subtract 3618 from 3891 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 9:
When dividing 2730 by 603, we get 4 with a remainder of 318.
Use 4 as the next digit of our solution. 
Result so far: 36136.4
The remainder is 318 after subtracting 2412 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 10:
If we divide 3180 by 603, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 36136.45
Subtracting 3015 from 3180 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 11:
1650 divided by 603 is 2 with a remainder of 444.
The number 2 becomes the next digit in our result. 
Result so far: 36136.452
If we subtract 1206 from 1650, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 12:
4440 divided by 603 is 7 with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 36136.4527
The remainder is 219 after subtracting 4221 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 13:
2190 divided by 603 is 3 with a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 36136.45273
If we subtract 1809 from 2190, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 14:
The number 603 fits into 3810 6 times, leaving a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 36136.452736
Deduct 3618 from 3810 and we're left 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.

On to step 15:
The number 603 fits into 1920 3 times, leaving a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 36136.4527363
Subtracting 1809 from 1920 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 16:
1110 divided by 603 is 1 with a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 36136.45273631
The remainder is 507 after subtracting 603 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

In conclusion, the division gives 36136.45273631 with a balance of 5.07e-07.
