We're dividing 21727923 by 70 
The aim is to understand the frequency of 70 in 21727923.

Advancing to step 1:
When dividing 2 by 70, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 70

Advancing to step 2:
When dividing 21 by 70, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 70

Let's proceed to step 3:
If we divide 217 by 70, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 210 from 217 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 70

Going ahead to step 4:
If we divide 72 by 70, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 70 away from 72, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 70

Advancing to step 5:
When dividing 27 by 70, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 310.0
Subtracting 0 from 27 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 70

Going ahead to step 6:
The number 70 fits into 279 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 3103.0
If we subtract 210 from 279, we get 69.
Take the next digit (2) from the dividend and append it to 69, then repeat: 692 / 70

Let's proceed to step 7:
70 goes into 692 9 times with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 31039.0
Subtract 630 from 692 to get 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 70

Going ahead to step 8:
If we divide 623 by 70, we get 8 and a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 310398.0
If we subtract 560 from 623, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
630 divided by 70 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 310398.9
If we subtract 630 from 630, 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 10:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 310398.9
If we subtract 0 from 0, 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.

Moving on to step 11:
When dividing 0 by 70, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 310398.9
If we take 0 away from 0, we end up 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.

The final result is 310398.9 with a remainder of 0.0.
