We look at the division of 80108521 by 602 
Our goal is to divide 80108521 by 602.

Moving on to step 1:
602 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 602

Advancing to step 2:
602 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 602

Going ahead to step 3:
The number 602 fits into 801 1 times, leaving a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 602 away from 801, we end up with 199.
Append the next digit (0) from the dividend to 199 and continue with: 1990 / 602

On to step 4:
1990 divided by 602 is 3 with a remainder of 184.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1806 from 1990 and we're left with 184.
Append the next digit (8) from the dividend to 184 and continue with: 1848 / 602

Advancing to step 5:
602 can be fit into 1848 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtract 1806 from 1848 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 602

Moving on to step 6:
The number 602 fits into 425 0 times, leaving a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 1330.0
If we take 0 away from 425, we end up with 425.
Bring next digit (2) of the dividend behind the 425 and repeat the process: 4252 / 602

On to step 7:
When dividing 4252 by 602, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 13307.0
If we take 4214 away from 4252, we end up with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 602

Going ahead to step 8:
602 goes into 381 0 times with a remainder of 381.
The next digit of our result is 0. 
Result so far: 133070.0
The remainder is 381 after subtracting 0 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
3810 divided by 602 is 6 with a remainder of 198.
The next digit of our result is 6. 
Result so far: 133070.6
Subtract 3612 from 3810 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 10:
When dividing 1980 by 602, we get 3 with a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 133070.63
Subtract 1806 from 1980 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
When dividing 1740 by 602, we get 2 with a remainder of 536.
The next digit of our result is 2. 
Result so far: 133070.632
If we take 1204 away from 1740, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 12:
When dividing 5360 by 602, we get 8 with a remainder of 544.
Put 8 as the next digit of the answer. 
Result so far: 133070.6328
If we take 4816 away from 5360, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 13:
The number 602 fits into 5440 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 133070.63289
If we take 5418 away from 5440, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
602 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 133070.63289
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
2200 divided by 602 is 3 with a remainder of 394.
Record the quotient 3 as the next digit in the result. 
Result so far: 133070.6328903
Subtract 1806 from 2200 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 16:
602 can be fit into 3940 6 times, resulting in a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 133070.63289036
Deduct 3612 from 3940 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 133070.63289036, and the remainder is 3.28e-07.
