449546 ÷ 70 
The aim is to understand the frequency of 70 in 449546.

Advancing to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 70

Going ahead to step 2:
70 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 70

Moving on to step 3:
The number 70 fits into 449 6 times, leaving a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 420 from 449 and we're left with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 70

Let's proceed to step 4:
295 divided by 70 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 280 from 295 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 70

Going ahead to step 5:
If we divide 154 by 70, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
Deduct 140 from 154 and we're left with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 70

Moving on to step 6:
70 can be fit into 146 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 6422.0
Subtract 140 from 146 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 70 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 6422.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 6422.08
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6422.085
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 6422.0857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 6422.08571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6422.085714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 6422.0857142
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 6422.08571428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 6422.08571428 with a remainder of 4e-08.
