We look at the division of 998397 by 70 
The aim is to understand the frequency of 70 in 998397.

Step 1:
When dividing 9 by 70, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 70

Going ahead to step 2:
When dividing 99 by 70, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 99 and we're left with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 70

Let's proceed to step 3:
70 goes into 298 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 14.0
If we take 280 away from 298, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 70

Let's proceed to step 4:
183 divided by 70 is 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we take 140 away from 183, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 70

On to step 5:
70 goes into 439 6 times with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 1426.0
The remainder is 19 after subtracting 420 from 439.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 70

Let's proceed to step 6:
70 goes into 197 2 times with a remainder of 57.
The next digit of our result is 2. 
Result so far: 14262.0
The remainder is 57 after subtracting 140 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
When dividing 570 by 70, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 14262.8
The remainder is 10 after subtracting 560 from 570.
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 8:
70 goes into 100 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 14262.81
Deduct 70 from 100 and we're left with 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 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 14262.814
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.

Advancing to step 10:
200 divided by 70 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 14262.8142
Deduct 140 from 200 and we're left 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.

On to step 11:
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: 14262.81428
If we take 560 away from 600, we end up 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.

On to step 12:
70 goes into 400 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 14262.814285
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.

Advancing to step 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 14262.8142857
If we subtract 490 from 500, we 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.

Moving on to step 14:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 14262.81428571
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.

The quotient of the division is 14262.81428571, and the remainder is 3e-08.
