We look at the division of 853494 by 70 
The aim is to understand the frequency of 70 in 853494.

Step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 70

Moving on to step 2:
70 goes into 85 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 70 from 85 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 70

Advancing to step 3:
When dividing 153 by 70, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 13 after subtracting 140 from 153.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 70

Let's proceed to step 4:
70 goes into 134 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 70 from 134 leaves us with 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 70

Advancing to step 5:
If we divide 649 by 70, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 1219.0
If we take 630 away from 649, we end up with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 70

Going ahead to step 6:
70 goes into 194 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 12192.0
Deduct 140 from 194 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
If we divide 540 by 70, we get 7 and a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 12192.7
The remainder is 50 after subtracting 490 from 540.
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 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 12192.77
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 12192.77, with a leftover of 0.01.
