We look at the division of 849665 by 70 
The aim is to understand the frequency of 70 in 849665.

Moving on to step 1:
70 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 70

Advancing to step 2:
84 divided by 70 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 70 from 84 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 70

Let's proceed to step 3:
If we divide 149 by 70, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 140 away from 149, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 70

Going ahead to step 4:
The number 70 fits into 96 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 70 from 96 and we're left with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 70

Advancing to step 5:
If we divide 266 by 70, we get 3 and a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 1213.0
Deduct 210 from 266 and we're left with 56.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 70

On to step 6:
The number 70 fits into 565 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 12138.0
Deduct 560 from 565 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 70, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12138.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 12138.07
Deduct 490 from 500 and we're left with 10.
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 9:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 12138.071
If we subtract 70 from 100, we get 30.
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 10:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 12138.0714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12138.07142
If we subtract 140 from 200, 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.

Step 12:
70 goes into 600 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 12138.071428
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.

On to step 13:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12138.0714285
If we take 350 away from 400, we end up 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.

Advancing to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 12138.07142857
If we take 490 away from 500, we end up with 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 result is 12138.07142857 with a remainder of 1e-08.
