99904 divided by 70 
The aim is to understand the frequency of 70 in 99904.

On to 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
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 70

Let's proceed to step 2:
The number 70 fits into 99 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 70 from 99 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 70

Let's proceed to step 3:
70 can be fit into 299 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 280 from 299 and we're left with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 70

Let's proceed to step 4:
190 divided by 70 is 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 140 from 190, we get 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 70

Let's proceed to step 5:
If we divide 504 by 70, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 1427.0
Subtract 490 from 504 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
The number 70 fits into 140 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1427.2
If we take 140 away from 140, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 70 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1427.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1427.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1427.2, with a leftover of 0.0.
