20828310 divided by 668 
We're looking to find how many times 668 goes into 20828310.

Moving on to step 1:
If we divide 2 by 668, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 668

Step 2:
The number 668 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 668

On to step 3:
When dividing 208 by 668, we get 0 with a remainder of 208.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 208 to get 208.
Bring next digit (2) of the dividend behind the 208 and repeat the process: 2082 / 668

Going ahead to step 4:
668 can be fit into 2082 3 times, resulting in a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2004 from 2082, we get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 668

Going ahead to step 5:
The number 668 fits into 788 1 times, leaving a remainder of 120.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 668 from 788, we get 120.
Include the next digit (3) from the dividend after 120, then repeat: 1203 / 668

Step 6:
If we divide 1203 by 668, we get 1 and a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Deduct 668 from 1203 and we're left with 535.
Include the next digit (1) from the dividend after 535, then repeat: 5351 / 668

Step 7:
When dividing 5351 by 668, we get 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 3118.0
Deduct 5344 from 5351 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 668

Going ahead to step 8:
The number 668 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 31180.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
668 can be fit into 700 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 31180.1
If we take 668 away from 700, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
668 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 31180.1
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
The number 668 fits into 3200 4 times, leaving a remainder of 528.
Use 4 as the next digit of our solution. 
Result so far: 31180.104
Deduct 2672 from 3200 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 12:
If we divide 5280 by 668, we get 7 and a remainder of 604.
Use 7 as the next digit of our solution. 
Result so far: 31180.1047
If we subtract 4676 from 5280, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 13:
When dividing 6040 by 668, we get 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 31180.10479
Deduct 6012 from 6040 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
668 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 31180.10479
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
The number 668 fits into 2800 4 times, leaving a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 31180.1047904
Subtract 2672 from 2800 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
The number 668 fits into 1280 1 times, leaving a remainder of 612.
Put 1 as the next digit of the answer. 
Result so far: 31180.10479041
If we take 668 away from 1280, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

After the division, we end up with 31180.10479041 and a remainder of 6.12e-07.
