We look at the division of 801072 by 70 
The aim is to understand the frequency of 70 in 801072.

Step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 70

Step 2:
70 can be fit into 80 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 80 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 70

Advancing to step 3:
70 can be fit into 101 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 70 from 101 to get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 70

Going ahead to step 4:
The number 70 fits into 310 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 280 away from 310, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 70

Step 5:
307 divided by 70 is 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 1144.0
If we subtract 280 from 307, we get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 70

Step 6:
The number 70 fits into 272 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 11443.0
Deduct 210 from 272 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
If we divide 620 by 70, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 11443.8
Subtract 560 from 620 to get 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:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 11443.88
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 11443.88 with a remaining 0.04.
