We're dividing 81203351 by 662 
We're looking to find how many times 662 goes into 81203351.

Let's proceed to step 1:
662 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 662

Step 2:
81 divided by 662 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 662

On to step 3:
If we divide 812 by 662, we get 1 and a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 662 from 812, we get 150.
Take the next digit (0) from the dividend and append it to 150, then repeat: 1500 / 662

Let's proceed to step 4:
When dividing 1500 by 662, we get 2 with a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1324 from 1500 leaves us with 176.
Append the next digit (3) from the dividend to 176 and continue with: 1763 / 662

On to step 5:
1763 divided by 662 is 2 with a remainder of 439.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 439 after subtracting 1324 from 1763.
Take the next digit (3) from the dividend and append it to 439, then repeat: 4393 / 662

Let's proceed to step 6:
The number 662 fits into 4393 6 times, leaving a remainder of 421.
Put 6 as the next digit of the answer. 
Result so far: 1226.0
The remainder is 421 after subtracting 3972 from 4393.
Include the next digit (5) from the dividend after 421, then repeat: 4215 / 662

Let's proceed to step 7:
When dividing 4215 by 662, we get 6 with a remainder of 243.
The next digit of our result is 6. 
Result so far: 12266.0
Deduct 3972 from 4215 and we're left with 243.
Fetch the next digit (1) from the dividend, attach it to 243 and continue: 2431 / 662

On to step 8:
When dividing 2431 by 662, we get 3 with a remainder of 445.
The next digit of our result is 3. 
Result so far: 122663.0
If we take 1986 away from 2431, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 9:
The number 662 fits into 4450 6 times, leaving a remainder of 478.
Write down 6 as next digit of the result. 
Result so far: 122663.6
If we subtract 3972 from 4450, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 10:
662 goes into 4780 7 times with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 122663.67
Deduct 4634 from 4780 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
662 can be fit into 1460 2 times, resulting in a remainder of 136.
The next digit of our result is 2. 
Result so far: 122663.672
Subtract 1324 from 1460 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
When dividing 1360 by 662, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 122663.6722
If we take 1324 away from 1360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 122663.6722 and a remainder of 0.00036.
