21316352 divided by 677 
The aim is to understand the frequency of 677 in 21316352.

Advancing to step 1:
2 divided by 677 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 677

Going ahead to step 2:
The number 677 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 677

Going ahead to step 3:
677 goes into 213 0 times with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Take the next digit (1) from the dividend and append it to 213, then repeat: 2131 / 677

On to step 4:
677 goes into 2131 3 times with a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2031 from 2131 and we're left with 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 677

Going ahead to step 5:
1006 divided by 677 is 1 with a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 677 from 1006 to get 329.
Include the next digit (3) from the dividend after 329, then repeat: 3293 / 677

Moving on to step 6:
The number 677 fits into 3293 4 times, leaving a remainder of 585.
Record the quotient 4 as the next digit in the result. 
Result so far: 314.0
The remainder is 585 after subtracting 2708 from 3293.
Bring next digit (5) of the dividend behind the 585 and repeat the process: 5855 / 677

Step 7:
If we divide 5855 by 677, we get 8 and a remainder of 439.
The next digit of our result is 8. 
Result so far: 3148.0
If we take 5416 away from 5855, we end up with 439.
Take the next digit (2) from the dividend and append it to 439, then repeat: 4392 / 677

Moving on to step 8:
4392 divided by 677 is 6 with a remainder of 330.
The number 6 becomes the next digit in our result. 
Result so far: 31486.0
If we subtract 4062 from 4392, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 9:
677 goes into 3300 4 times with a remainder of 592.
The next digit of our result is 4. 
Result so far: 31486.4
If we take 2708 away from 3300, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 10:
677 goes into 5920 8 times with a remainder of 504.
Use 8 as the next digit of our solution. 
Result so far: 31486.48
The remainder is 504 after subtracting 5416 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 11:
5040 divided by 677 is 7 with a remainder of 301.
Use 7 as the next digit of our solution. 
Result so far: 31486.487
Deduct 4739 from 5040 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
677 can be fit into 3010 4 times, resulting in a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 31486.4874
If we subtract 2708 from 3010, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 13:
When dividing 3020 by 677, we get 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 31486.48744
Subtracting 2708 from 3020 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 31486.48744, and the remainder is 0.000312.
