We look at the division of 66138059 by 818 
Our goal is to divide 66138059 by 818.

Moving on to step 1:
The number 818 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 818

Advancing to step 2:
If we divide 66 by 818, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 818

Step 3:
The number 818 fits into 661 0 times, leaving a remainder of 661.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Take the next digit (3) from the dividend and append it to 661, then repeat: 6613 / 818

Step 4:
818 can be fit into 6613 8 times, resulting in a remainder of 69.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6544 away from 6613, we end up with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 818

Going ahead to step 5:
When dividing 698 by 818, we get 0 with a remainder of 698.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 698 after subtracting 0 from 698.
Bring next digit (0) of the dividend behind the 698 and repeat the process: 6980 / 818

Advancing to step 6:
818 goes into 6980 8 times with a remainder of 436.
The next digit of our result is 8. 
Result so far: 808.0
Deduct 6544 from 6980 and we're left with 436.
Include the next digit (5) from the dividend after 436, then repeat: 4365 / 818

On to step 7:
4365 divided by 818 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 8085.0
If we take 4090 away from 4365, we end up with 275.
Append the next digit (9) from the dividend to 275 and continue with: 2759 / 818

On to step 8:
The number 818 fits into 2759 3 times, leaving a remainder of 305.
Use 3 as the next digit of our solution. 
Result so far: 80853.0
Subtract 2454 from 2759 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 9:
The number 818 fits into 3050 3 times, leaving a remainder of 596.
The next digit of our result is 3. 
Result so far: 80853.3
If we take 2454 away from 3050, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 10:
The number 818 fits into 5960 7 times, leaving a remainder of 234.
The next digit of our result is 7. 
Result so far: 80853.37
If we subtract 5726 from 5960, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 11:
2340 divided by 818 is 2 with a remainder of 704.
Use 2 as the next digit of our solution. 
Result so far: 80853.372
If we take 1636 away from 2340, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 12:
818 goes into 7040 8 times with a remainder of 496.
Use 8 as the next digit of our solution. 
Result so far: 80853.3728
Deduct 6544 from 7040 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 13:
When dividing 4960 by 818, we get 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 80853.37286
Subtract 4908 from 4960 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
If we divide 520 by 818, we get 0 and a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 80853.37286
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 15:
818 goes into 5200 6 times with a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 80853.3728606
If we subtract 4908 from 5200, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 16:
When dividing 2920 by 818, we get 3 with a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 80853.37286063
If we subtract 2454 from 2920, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

In conclusion, the division gives 80853.37286063 with a balance of 4.66e-07.
