21263879 divided by 676 
We want to figure out the number of times 21263879 can be divided by 676.

Let's proceed to step 1:
676 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 676

Let's proceed to step 2:
If we divide 21 by 676, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 676

Step 3:
If we divide 212 by 676, we get 0 and a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Take the next digit (6) from the dividend and append it to 212, then repeat: 2126 / 676

Advancing to step 4:
The number 676 fits into 2126 3 times, leaving a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 98 after subtracting 2028 from 2126.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 676

Step 5:
676 goes into 983 1 times with a remainder of 307.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 307 after subtracting 676 from 983.
Grab the next digit (8) from the dividend, add it to 307, then carry on: 3078 / 676

Let's proceed to step 6:
3078 divided by 676 is 4 with a remainder of 374.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtract 2704 from 3078 to get 374.
Take the next digit (7) from the dividend and append it to 374, then repeat: 3747 / 676

Let's proceed to step 7:
676 can be fit into 3747 5 times, resulting in a remainder of 367.
The number 5 becomes the next digit in our result. 
Result so far: 3145.0
The remainder is 367 after subtracting 3380 from 3747.
Append the next digit (9) from the dividend to 367 and continue with: 3679 / 676

Step 8:
676 goes into 3679 5 times with a remainder of 299.
Write down 5 as next digit of the result. 
Result so far: 31455.0
Deduct 3380 from 3679 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 9:
676 can be fit into 2990 4 times, resulting in a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 31455.4
The remainder is 286 after subtracting 2704 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
676 can be fit into 2860 4 times, resulting in a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 31455.44
Subtract 2704 from 2860 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final result is 31455.44 with a remainder of 0.156.
