Let's divide 30953340 by 686
Our goal is to divide 30953340 by 686.

Moving on to step 1:
686 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 686

Going ahead to step 2:
686 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 686

On to step 3:
309 divided by 686 is 0 with a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Include the next digit (5) from the dividend after 309, then repeat: 3095 / 686

On to step 4:
When dividing 3095 by 686, we get 4 with a remainder of 351.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2744 away from 3095, we end up with 351.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 686

Step 5:
3513 divided by 686 is 5 with a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 3430 from 3513 and we're left with 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 686

Step 6:
686 can be fit into 833 1 times, resulting in a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
Deduct 686 from 833 and we're left with 147.
Grab the next digit (4) from the dividend, add it to 147, then carry on: 1474 / 686

Step 7:
When dividing 1474 by 686, we get 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 4512.0
The remainder is 102 after subtracting 1372 from 1474.
Bring next digit (0) of the dividend behind the 102 and repeat the process: 1020 / 686

Let's proceed to step 8:
When dividing 1020 by 686, we get 1 with a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 45121.0
Subtract 686 from 1020 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 9:
686 can be fit into 3340 4 times, resulting in a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 45121.4
If we subtract 2744 from 3340, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
686 can be fit into 5960 8 times, resulting in a remainder of 472.
Use 8 as the next digit of our solution. 
Result so far: 45121.48
If we take 5488 away from 5960, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
686 goes into 4720 6 times with a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 45121.486
Deduct 4116 from 4720 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 12:
686 goes into 6040 8 times with a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 45121.4868
If we take 5488 away from 6040, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 13:
If we divide 5520 by 686, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 45121.48688
If we subtract 5488 from 5520, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 45121.48688, with a leftover of 3.2e-05.
