21005044 divided by 602 
We want to figure out the number of times 21005044 can be divided by 602.

Advancing to step 1:
602 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 602

On to step 2:
If we divide 21 by 602, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 602

Going ahead to step 3:
The number 602 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 602

On to step 4:
2100 divided by 602 is 3 with a remainder of 294.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1806 from 2100 to get 294.
Fetch the next digit (5) from the dividend, attach it to 294 and continue: 2945 / 602

Advancing to step 5:
When dividing 2945 by 602, we get 4 with a remainder of 537.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 2408 from 2945 leaves us with 537.
Append the next digit (0) from the dividend to 537 and continue with: 5370 / 602

Let's proceed to step 6:
602 goes into 5370 8 times with a remainder of 554.
Use 8 as the next digit of our solution. 
Result so far: 348.0
If we take 4816 away from 5370, we end up with 554.
Bring next digit (4) of the dividend behind the 554 and repeat the process: 5544 / 602

On to step 7:
The number 602 fits into 5544 9 times, leaving a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 3489.0
If we subtract 5418 from 5544, we get 126.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 602

Advancing to step 8:
If we divide 1264 by 602, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 34892.0
The remainder is 60 after subtracting 1204 from 1264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
The number 602 fits into 600 0 times, leaving a remainder of 600.
The next digit of our result is 0. 
Result so far: 34892.0
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
The number 602 fits into 6000 9 times, leaving a remainder of 582.
Use 9 as the next digit of our solution. 
Result so far: 34892.09
If we subtract 5418 from 6000, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Moving on to step 11:
If we divide 5820 by 602, we get 9 and a remainder of 402.
Use 9 as the next digit of our solution. 
Result so far: 34892.099
If we take 5418 away from 5820, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 34892.099 with a remainder of 0.0402.
