We're dividing 21950796 by 406 
The aim is to understand the frequency of 406 in 21950796.

On to step 1:
406 goes into 2 0 times with 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 406

Moving on to step 2:
When dividing 21 by 406, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 406

Advancing to step 3:
406 goes into 219 0 times with a remainder of 219.
The next digit of our result is 0. 
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 / 406

Let's proceed to step 4:
406 can be fit into 2195 5 times, resulting in a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 165 after subtracting 2030 from 2195.
Fetch the next digit (0) from the dividend, attach it to 165 and continue: 1650 / 406

Step 5:
1650 divided by 406 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 1624 from 1650 to get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 406

Going ahead to step 6:
406 goes into 267 0 times with a remainder of 267.
The next digit of our result is 0. 
Result so far: 540.0
Subtracting 0 from 267 leaves us with 267.
Fetch the next digit (9) from the dividend, attach it to 267 and continue: 2679 / 406

Going ahead to step 7:
When dividing 2679 by 406, we get 6 with a remainder of 243.
Record the quotient 6 as the next digit in the result. 
Result so far: 5406.0
Subtracting 2436 from 2679 leaves us with 243.
Grab the next digit (6) from the dividend, add it to 243, then carry on: 2436 / 406

Advancing to step 8:
406 goes into 2436 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 54066.0
If we subtract 2436 from 2436, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
406 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54066.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 406 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54066.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 54066.0, and the remainder is 0.0.
