We look at the division of 35200806 by 686 
We want to figure out the number of times 35200806 can be divided by 686.

Step 1:
The number 686 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 686

Going ahead to step 2:
The number 686 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 686

Going ahead to step 3:
If we divide 352 by 686, we get 0 and a remainder of 352.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 352 leaves us with 352.
Append the next digit (0) from the dividend to 352 and continue with: 3520 / 686

Going ahead to step 4:
686 goes into 3520 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3430 from 3520 and we're left with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 686

Step 5:
When dividing 900 by 686, we get 1 with a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 686 from 900 leaves us with 214.
Include the next digit (8) from the dividend after 214, then repeat: 2148 / 686

Moving on to step 6:
If we divide 2148 by 686, we get 3 and a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 513.0
Deduct 2058 from 2148 and we're left with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 686

Let's proceed to step 7:
900 divided by 686 is 1 with a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 5131.0
The remainder is 214 after subtracting 686 from 900.
Bring next digit (6) of the dividend behind the 214 and repeat the process: 2146 / 686

Let's proceed to step 8:
When dividing 2146 by 686, we get 3 with a remainder of 88.
The next digit of our result is 3. 
Result so far: 51313.0
If we subtract 2058 from 2146, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
If we divide 880 by 686, we get 1 and a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 51313.1
Subtracting 686 from 880 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
686 goes into 1940 2 times with a remainder of 568.
Put 2 as the next digit of the answer. 
Result so far: 51313.12
If we take 1372 away from 1940, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 11:
686 can be fit into 5680 8 times, resulting in a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 51313.128
Deduct 5488 from 5680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
1920 divided by 686 is 2 with a remainder of 548.
Put 2 as the next digit of the answer. 
Result so far: 51313.1282
Subtract 1372 from 1920 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 13:
The number 686 fits into 5480 7 times, leaving a remainder of 678.
The next digit of our result is 7. 
Result so far: 51313.12827
The remainder is 678 after subtracting 4802 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 14:
686 goes into 6780 9 times with a remainder of 606.
The next digit of our result is 9. 
Result so far: 51313.128279
Subtracting 6174 from 6780 leaves us with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 15:
686 can be fit into 6060 8 times, resulting in a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 51313.1282798
Deduct 5488 from 6060 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 16:
5720 divided by 686 is 8 with a remainder of 232.
The next digit of our result is 8. 
Result so far: 51313.12827988
Subtracting 5488 from 5720 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final outcome is 51313.12827988, with a leftover of 2.32e-07.
