83915512 ÷ 206 
We want to figure out the number of times 83915512 can be divided by 206.

Going ahead to step 1:
When dividing 8 by 206, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 206

Advancing to step 2:
206 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 206

Going ahead to step 3:
206 can be fit into 839 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 824 from 839, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 206

Going ahead to step 4:
206 can be fit into 151 0 times, resulting in a remainder of 151.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 151 leaves us with 151.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 206

Moving on to step 5:
1515 divided by 206 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
If we take 1442 away from 1515, we end up with 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 206

Step 6:
206 can be fit into 735 3 times, resulting in a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 4073.0
If we subtract 618 from 735, we get 117.
Append the next digit (1) from the dividend to 117 and continue with: 1171 / 206

On to step 7:
206 goes into 1171 5 times with a remainder of 141.
The number 5 becomes the next digit in our result. 
Result so far: 40735.0
If we take 1030 away from 1171, we end up with 141.
Include the next digit (2) from the dividend after 141, then repeat: 1412 / 206

Moving on to step 8:
When dividing 1412 by 206, we get 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 407356.0
Subtract 1236 from 1412 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 9:
206 can be fit into 1760 8 times, resulting in a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 407356.8
Subtracting 1648 from 1760 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
The number 206 fits into 1120 5 times, leaving a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 407356.85
The remainder is 90 after subtracting 1030 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
If we divide 900 by 206, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 407356.854
The remainder is 76 after subtracting 824 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
760 divided by 206 is 3 with a remainder of 142.
The next digit of our result is 3. 
Result so far: 407356.8543
Deduct 618 from 760 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 13:
1420 divided by 206 is 6 with a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 407356.85436
The remainder is 184 after subtracting 1236 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 14:
206 can be fit into 1840 8 times, resulting in a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 407356.854368
The remainder is 192 after subtracting 1648 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 15:
When dividing 1920 by 206, we get 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 407356.8543689
The remainder is 66 after subtracting 1854 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
The number 206 fits into 660 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 407356.85436893
If we subtract 618 from 660, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 407356.85436893 with a balance of 4.2e-08.
