We look at the division of 30631971 by 818 
We're looking to find how many times 818 goes into 30631971.

Let's proceed to step 1:
When dividing 3 by 818, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 818

Moving on to step 2:
If we divide 30 by 818, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 818

Step 3:
306 divided by 818 is 0 with a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Include the next digit (3) from the dividend after 306, then repeat: 3063 / 818

Moving on to step 4:
If we divide 3063 by 818, we get 3 and a remainder of 609.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2454 from 3063 to get 609.
Take the next digit (1) from the dividend and append it to 609, then repeat: 6091 / 818

Advancing to step 5:
The number 818 fits into 6091 7 times, leaving a remainder of 365.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 5726 away from 6091, we end up with 365.
Append the next digit (9) from the dividend to 365 and continue with: 3659 / 818

On to step 6:
If we divide 3659 by 818, we get 4 and a remainder of 387.
The next digit of our result is 4. 
Result so far: 374.0
Subtract 3272 from 3659 to get 387.
Append the next digit (7) from the dividend to 387 and continue with: 3877 / 818

Going ahead to step 7:
818 goes into 3877 4 times with a remainder of 605.
The number 4 becomes the next digit in our result. 
Result so far: 3744.0
If we subtract 3272 from 3877, we get 605.
Append the next digit (1) from the dividend to 605 and continue with: 6051 / 818

On to step 8:
The number 818 fits into 6051 7 times, leaving a remainder of 325.
The next digit of our result is 7. 
Result so far: 37447.0
If we subtract 5726 from 6051, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 9:
The number 818 fits into 3250 3 times, leaving a remainder of 796.
Put 3 as the next digit of the answer. 
Result so far: 37447.3
If we subtract 2454 from 3250, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Going ahead to step 10:
818 goes into 7960 9 times with a remainder of 598.
The next digit of our result is 9. 
Result so far: 37447.39
Subtracting 7362 from 7960 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 11:
If we divide 5980 by 818, we get 7 and a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 37447.397
If we subtract 5726 from 5980, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 12:
818 can be fit into 2540 3 times, resulting in a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 37447.3973
Subtracting 2454 from 2540 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
The number 818 fits into 860 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 37447.39731
The remainder is 42 after subtracting 818 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
When dividing 420 by 818, we get 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 37447.39731
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
The number 818 fits into 4200 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 37447.3973105
The remainder is 110 after subtracting 4090 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
If we divide 1100 by 818, we get 1 and a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 37447.39731051
If we subtract 818 from 1100, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

In conclusion, the division gives 37447.39731051 with a balance of 2.82e-07.
