21953993 divided by 682 
The aim is to understand the frequency of 682 in 21953993.

Step 1:
If we divide 2 by 682, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 682

Advancing to step 2:
682 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 682

Let's proceed to step 3:
If we divide 219 by 682, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Grab the next digit (5) from the dividend, add it to 219, then carry on: 2195 / 682

Step 4:
2195 divided by 682 is 3 with a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2046 from 2195 and we're left with 149.
Fetch the next digit (3) from the dividend, attach it to 149 and continue: 1493 / 682

On to step 5:
If we divide 1493 by 682, we get 2 and a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 1364 from 1493 and we're left with 129.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 682

Going ahead to step 6:
When dividing 1299 by 682, we get 1 with a remainder of 617.
Write down 1 as next digit of the result. 
Result so far: 321.0
If we subtract 682 from 1299, we get 617.
Append the next digit (9) from the dividend to 617 and continue with: 6179 / 682

Let's proceed to step 7:
The number 682 fits into 6179 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 3219.0
If we take 6138 away from 6179, we end up with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 682

Let's proceed to step 8:
413 divided by 682 is 0 with a remainder of 413.
The next digit of our result is 0. 
Result so far: 32190.0
Subtract 0 from 413 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 9:
682 can be fit into 4130 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 32190.6
Subtract 4092 from 4130 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
682 can be fit into 380 0 times, resulting in a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 32190.6
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
The number 682 fits into 3800 5 times, leaving a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 32190.605
If we subtract 3410 from 3800, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 12:
682 goes into 3900 5 times with a remainder of 490.
Record the quotient 5 as the next digit in the result. 
Result so far: 32190.6055
Deduct 3410 from 3900 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Our division results in 32190.6055 with a remaining 0.0049.
