We're dividing 787212 by 70 
The aim is to understand the frequency of 70 in 787212.

Step 1:
If we divide 7 by 70, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 70

On to step 2:
If we divide 78 by 70, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 70 from 78, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 70

Going ahead to step 3:
87 divided by 70 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 70 from 87 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 70

Advancing to step 4:
70 goes into 172 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 140 from 172, we get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 70

Let's proceed to step 5:
70 can be fit into 321 4 times, resulting in a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 1124.0
If we take 280 away from 321, we end up with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 70

Going ahead to step 6:
The number 70 fits into 412 5 times, leaving a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 11245.0
Subtract 350 from 412 to get 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:
70 can be fit into 620 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 11245.8
If we subtract 560 from 620, we 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.

Moving on to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 11245.88
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 outcome is 11245.88, with a leftover of 0.04.
