26921794 ÷ 406 
The aim is to understand the frequency of 406 in 26921794.

On to step 1:
When dividing 2 by 406, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 406

Advancing to step 2:
The number 406 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 406

Advancing to step 3:
The number 406 fits into 269 0 times, leaving a remainder of 269.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 269 to get 269.
Grab the next digit (2) from the dividend, add it to 269, then carry on: 2692 / 406

Step 4:
406 goes into 2692 6 times with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 2436 from 2692 leaves us with 256.
Take the next digit (1) from the dividend and append it to 256, then repeat: 2561 / 406

Let's proceed to step 5:
406 can be fit into 2561 6 times, resulting in a remainder of 125.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 2436 from 2561, we get 125.
Include the next digit (7) from the dividend after 125, then repeat: 1257 / 406

Step 6:
The number 406 fits into 1257 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 663.0
If we subtract 1218 from 1257, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 406

Moving on to step 7:
399 divided by 406 is 0 with a remainder of 399.
The next digit of our result is 0. 
Result so far: 6630.0
The remainder is 399 after subtracting 0 from 399.
Bring next digit (4) of the dividend behind the 399 and repeat the process: 3994 / 406

Moving on to step 8:
If we divide 3994 by 406, we get 9 and a remainder of 340.
Put 9 as the next digit of the answer. 
Result so far: 66309.0
Deduct 3654 from 3994 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
3400 divided by 406 is 8 with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 66309.8
Deduct 3248 from 3400 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
1520 divided by 406 is 3 with a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 66309.83
If we subtract 1218 from 1520, 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.

Step 11:
If we divide 3020 by 406, we get 7 and a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 66309.837
If we take 2842 away from 3020, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 12:
406 goes into 1780 4 times with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 66309.8374
The remainder is 156 after subtracting 1624 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 13:
406 goes into 1560 3 times with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 66309.83743
The remainder is 342 after subtracting 1218 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
3420 divided by 406 is 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 66309.837438
If we subtract 3248 from 3420, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 15:
406 can be fit into 1720 4 times, resulting in a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 66309.8374384
If we take 1624 away from 1720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
If we divide 960 by 406, we get 2 and a remainder of 148.
The next digit of our result is 2. 
Result so far: 66309.83743842
If we subtract 812 from 960, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The quotient of the division is 66309.83743842, and the remainder is 1.48e-07.
